JIRA: https://jira.spring.io/browse/INT-3376 Allow user annotations with Messaging Meta-Annotations override/supplement attributes set on the meta-Annotation. PR Comments and More - Do not create a bean definition for the annotation (interface) when `MessagingGateway` is used as a meta-Annotation. - For a `MessagingGateway` restore attributes overridden with empty values - Other PR comments. Fully support meta-Annotation hierarchy. Polishing: * Upgrade JRuby to 1.7.12 * Replace `AnnotationFinder` with moving its methods to `MessagingAnnotationUtils` * Refactor aggregator classes to use `MessagingAnnotationUtils` to determine the method for annotation * Fix `IntegrationComponentScanRegistrar` to skip annotation classes * Fix `MessagingGatewayRegistrar#replaceEmptyOverrides` * Improve `MessagingAnnotationPostProcessor` to use `ReflectionUtils.USER_DECLARED_METHODS` `MethodFilter` * Change the `MethodAnnotationPostProcessor` hierarchy to use just list of annotations to process attributes
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
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
