* INT-4381: MessageSources refactoring JIRA: https://jira.spring.io/browse/INT-4381 * Make all the out-of-the-box `MessageSource` implementations based on the `AbstractMessageSource` * Fix `JdbcPollingChannelAdapterIntegrationTests` for sporadic failure because of `fixed-rate` for the poller * Fix HeaderEnricherTests race condition The `errorChannel()` expect an error in the `testErrorChannel` after `1000` ms, but at the same time the `poller` in configured for the `3000` ms. * Increase all the timeouts for replies * Decrease a `fixed-delay` on the `poller` * Some other code style polishing for the `HeaderEnricherTests`
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
