* Fix `SmartLifecycle.stop(Runnable)` usage We always have to call `callback` in the `SmartLifecycle.stop(Runnable)` implementation independently of component state * Fix `StandardIntegrationFlow.stop(Runnable)` for a logic when we don't have any `this.lifecycles` * Remove those `stop(Runnable)` which are fully equivalent of the `default` on in the `SmartLifecycle` * Some other simple polishing for the affected classes, e.g. `isSingleton()` is `default` with `true` in the `InitializingBean` **Cherry-pick to 5.1.x** * * Fix checkstyle violation
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
