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

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.

To generate IDEA metadata (.iml and .ipr files), do the following:

./gradlew idea
