JIRA: https://jira.spring.io/browse/INT-3510 There has been an error in schema creation scipt for message store on postgresql database: The statement for creating sequence 'INT_MESSAGE_SEQ' was executed AFTER creating the table that actually uses this sequence which resulted in sequence not found error. Further problem was that the the corresponding index 'MSG_INDEX_DATE_IDX' in creation script does not match the index name 'INT_CHANNEL_MSG_DATE_IDX' in drop script. Therfore an error occurred when executing drop schema script for postgresql. Fixes: 1.Moved creation of sequence 'INT_MESSAGE_SEQ' to first line to be executed before creating the corresponding table 2.Renamed index 'MSG_INDEX_DATE_IDX' to 'INT_CHANNEL_MSG_DATE_IDX' in create script to make drop script work again On branch INT-3510

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
