+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+= Spring Cloud Stream & Task Maven Documentation Plugin
+
+Maven plugin for generating documentation for Spring Cloud stream and task app starters.
+
+Assuming a Spring Cloud Stream / Task app (or app starter) has
+specified selected configuration properties to be visible (i.e., providing src/main/resources/META-INF/dataflow-configuration-metadata.properties),
+this plugin will help automate the documentation of such properties.
+https://docs.spring.io/spring-cloud-dataflow/docs/1.1.0.M2/reference/html/spring-cloud-dataflow-register-apps.html#spring-cloud-dataflow-stream-app-whitelisting[whitelisted]
+some configuration properties, this plugin will help automate the documentation of such properties.
+
+== Usage
+
+To use this plugin, simply add the following markers to your project `README.adoc` file:
+
+```
+//tag::configuration-properties[]
+//end::configuration-properties[]
+```
+
+
+Then, configure this plugin for your app project (either directly or through a parent POM):
+```
+	<build>
+		<plugins>
+			<plugin>
+				<groupId>org.springframework.cloud.stream.app.plugin</groupId>
+				<artifactId>spring-cloud-stream-app-documentation-maven-plugin</artifactId>
+				<version>1.0.0.BUILD-SNAPSHOT</version>
+				<executions>
+					<execution>
+						<id>generate-documentation</id>
+						<phase>verify</phase>
+						<goals>
+							<goal>generate-documentation</goal>
+						</goals>
+					</execution>
+				</executions>
+			</plugin>
+		</plugins>
+	</build>
+```
+
+Documentation for the visible properties shall appear on next build, which should be committed under VCS.

+
+Maven plugin for generating spring cloud stream applications: https://github.com/spring-cloud/stream-applications
+It generates a separate maven project for every configured binder.
+
+Plugin `Application` section helps to configure the application project independently form the Binders that
+can be used. The `Binders` section helps to define the Binder specific configurations, that are merged to
+the `Application` configurations to generate the binder specific maven projects.
+
+The `Global` section (e.g. `global.application` and `global.binders`) helps to define configurations sharable
+between many Applications and Binders.
+
+As the following diagram illustrates, both the `Application` and the
+`Binder` allow configuring various application and maven properties:
+
+image::src/main/resources/doc/MojoConfiguration.jpg[]
+
+== Build
+
+mvn clean package [Requires JDK 8]
+
+== Sample Configuration for generating spring cloud stream apps
+
+In the parent POM define the `Application` and `Binder` configurations common for all applications to be generated.
+Do this under the `pluginManagement` pom section and use the plugin's `global` configuration:

+== Configure Solace and Pubsub binders support
+
+To generate applications for https://github.com/SolaceProducts/spring-cloud-stream-binder-solace[Solace] binders, extend your `binders` section with following configuration:
+
+[source, xml]
+----
+    <binders>
+        ....
+        <solace>
+            <maven>
+                <dependencies>
+                    <dependency>
+                        <groupId>com.solace.spring.cloud</groupId>
+                        <artifactId>spring-cloud-starter-stream-solace</artifactId>
+                        <version>1.2.1</version>
+                    </dependency>
+                </dependencies>
+            </maven>
+        </solace>
+        ....
+    </binders>
+----
+
+You can add it either to your application's POM or to the parent's `global` POM sections.
+
+Similar to generate application for the https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-pubsub-stream-binder[PubSub]
+binders and to your binders section configuration like this:
+
+[source, xml]
+----
+<binders>
+...
+    <pubsub>
+        <maven>
+            <dependencyManagement>
+                <dependency>
+                    <groupId>org.springframework.cloud</groupId>
+                    <artifactId>spring-cloud-gcp-dependencies</artifactId>
+                    <version>1.2.4.RELEASE</version>
+                </dependency>
+            </dependencyManagement>
+            <dependencies>
+                <dependency>

+                </dependency>

+        </maven>
+    </pubsub>
+...
+</binders>

+
+== Custom Spring Boot Maven Plugin Configuration
+
+Spring Boot Maven plugin offers a number of customization options by specifying a configuration section in the plugin definition.
+For example, using the custom configuration, you can instruct the plugin to unpack a particular dependency.
+You would do that using Spring Boot Maven plugin as below.
+```
+<plugin>
+    <groupId>org.springframework.boot</groupId>
+    <artifactId>spring-boot-maven-plugin</artifactId>
+    <configuration>
+        <requiresUnpack>
+                    <dependency>
+                        <groupId>org.python</groupId>
+                        <artifactId>jython-standalone</artifactId>
+                    </dependency>
+                </requiresUnpack>
+    </configuration>
+</plugin>
+```
+
+When using the app generator plugin, you can ask the plugin to include this information when it generates the necessary XML snippets for adding the Spring Boot Maven plugin.
+Below is an example of doing so.
+```
+<plugin>
+    <groupId>org.springframework.cloud</groupId>
+    <artifactId>spring-cloud-dataflow-apps-generator-plugin</artifactId>
+    <configuration>
+        <application>
+            ...
+            <bootPluginConfiguration>
+                <![CDATA[
+                <requiresUnpack>
+                    <dependency>
+                        <groupId>org.python</groupId>
+                        <artifactId>jython-standalone</artifactId>
+                    </dependency>
+                </requiresUnpack>
+                ]]>
+            </bootPluginConfiguration>
+            ...
+        </application>
+    </configuration>
+```
+
+Pay attention to how the Spring Boot plugin configuration is wrapped inside a `CDATA` element.
+This is necessary for the app generator to properly parse this information.

+= Spring Cloud Stream & Task Maven Metadata Plugin
+
+Maven plugin for aggregating Spring Boot metadata from all dependencies of a project into
+a single metadata-only artifact.
+
+== Usage
+
+To use this plugin, configure this plugin for your app project (either directly or through a parent POM):
+```
+	<build>
+		<plugins>
+			<plugin>
+				<groupId>org.springframework.cloud.stream.app.plugin</groupId>
+				<artifactId>spring-cloud-app-starter-metadata-maven-plugin</artifactId>
+				<version>2.0.0.BUILD-SNAPSHOT</version>
+				<executions>
+					<execution>
+						<id>aggregate-metadata</id>
+						<phase>compile</phase>
+						<goals>
+							<goal>aggregate-metadata</goal>
+						</goals>
+					</execution>
+				</executions>
+			</plugin>
+		</plugins>
+	</build>
+```
+
+This will produce and attach to the build a jar file named `<artifactId>-<version>-metadata.jar` (`metadata` being the
+maven classifier used for the artifact, which can be customized as such:)
+```
+	<build>
+		<plugins>
+			<plugin>
+				<groupId>org.springframework.cloud.stream.app.plugin</groupId>
+				<artifactId>spring-cloud-app-starter-metadata-maven-plugin</artifactId>
+				<version>2.0.0.BUILD-SNAPSHOT</version>
+				<executions>
+					<execution>
+						<id>aggregate-metadata</id>
+						<phase>compile</phase>
+						<goals>
+							<goal>aggregate-metadata</goal>
+						</goals>
+						<configuration>
+						    <classifier>foobar</classifier>
+						</configuration>
+					</execution>
+				</executions>
+			</plugin>
+		</plugins>
+	</build>
+```
+
+You can filter in subset of the gathered metadata and store it into a java property file: `META-INF/spring-configuration-metadata-encoded.properties`.
+This file has single property `org.springframework.cloud.dataflow.spring.configuration.metadata.json` which contains the pre-filtered metadata encoded as Base64.
+To activate this feature you need to set the `storeFilteredMetadata` parameter to `true`. Use the `metadataFilter` to configure the whitelisted metadata content to include.
+For example:
+```
+<build>
+  <plugins>
+      <plugin>
+        <groupId>org.springframework.cloud</groupId>
+        <artifactId>spring-cloud-app-starter-metadata-maven-plugin</artifactId>
+        <version>2.0.0.BUILD-SNAPSHOT</version>
+
+        <configuration>
+          <storeFilteredMetadata>true</storeFilteredMetadata>
+
+          <metadataFilter>
+            <names>
+              <filter>server.port</filter>
+            </names>
+            <sourceTypes>
+              <filter>io.pivotal.java.function.http.supplier.HttpSourceProperties</filter>
+              <filter>io.pivotal.java.function.http.supplier.HttpSourceProperties$Cors</filter>
+            </sourceTypes>
+          </metadataFilter>
+        </configuration>
+
+        <executions>
+          <execution>
+            <id>aggregate-metadata</id>
+            <phase>compile</phase>
+            <goals>
+              <goal>aggregate-metadata</goal>
+            </goals>
+          </execution>
+        </executions>
+      </plugin>
