* Add `ConsumerSubscriber` to adapt `Consumer<?>` to the `Subscriber<?>` * Add `SubscribableChannelPublisherAdapter` to adapt `SubscribableChannel` to `Publisher<?>` via `Flux.create()` on subscription * Add `PollableChannelPublisherAdapter` to adapt `PollableChannel` to `Publisher<?>` via `Mono.delayMillis()` and `flatMap()` for `channel.receive()` Use `concatMap()` for `PollableChannel` Iterate `PollableChannel` until there is a data Fix Lambda signature error via explicit class declaration: ``` java.lang.ClassFormatError: Duplicate field name&signature in class file org/springframework/integration/endpoint/ReactiveConsumer$PollableChannelPublisherAdapter$1 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:760) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at org.springframework.integration.endpoint.ReactiveConsumer$PollableChannelPublisherAdapter.lambda$new$2(ReactiveConsumer.java:163) ``` Looks like Java bug: Move `Iterator<Message<?>>` instance to the `subscribe()` to avoid race conditions when we have several subscribers. In other words make `Iterator<Message<?>>` subscriber-specific, but at the same time avoid re-instantiation for each `Flux.concatMap()` call caused by the previous `repeat()` Upgrade to Reactor 3.0.3 and others * Make fixes according Reactor 3.0.3 changes * Remove redundant `TestSubscriber` in favor of `StepVerifier` and `mock(Subscriber)` * Rework `PublisherIntegrationFlow` Reactive Streams implementation to the out-of-the-box `ReactiveConsumer` and `ReactiveChannel`
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
