JIRA: https://jira.spring.io/browse/INT-4208 Since `AsyncRestTemplate` is deprecated in Spring 5.0, it doesn't make sense to promote that feature via our new `AsyncHttpRequestExecutingMessageHandler` component * Rework (and rename) `AsyncHttpRequestExecutingMessageHandler` to `ReactiveHttpRequestExecutingMessageHandler` and make it based on the WebFlux `WebClient` * Fix Java DSL (`ReactiveHttpMessageHandlerSpec`) and all tests according a new logic in the `ReactiveHttpRequestExecutingMessageHandler` * Fix XML namespace support to use new `ReactiveHttpRequestExecutingMessageHandler` and don't expose unused options like `converters` and `request-factory` * Fix `What's New` and `http.adoc` * To remain with `async` mode for the `ReactiveHttpRequestExecutingMessageHandler` behavior support fix `AbstractMessageProducingHandler` to adapt reply `Mono` to the `SettableListenableFuture` * Introduce new `reactive` behavior for the `AbstractMessageProducingHandler` when `outputChannel` is `ReactiveSubscribableChannel` and perform `.subscribeTo(Publisher)` for `Publisher` reply * Upgrade to Spring AMQP `2.0 M3` * Downgrade to Spring Security `4.2.2` Address PR comments Add async error handling to the one-way case Minor polishing and checkstyle fix
Spring Integration 
Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
