JIRA: https://jira.spring.io/browse/INT-4305 The `File.renameTo()` operation may fail, therefore the content of the local file isn't changed, but since we change `setLastModified()` anyway, this file might be eligible for local polling. So, we end up with the same content from local file in a new message, meanwhile we expect a new content from the remote file * Check the `File.renameTo()` result and attempt to `delete()` for existing local file * When file isn't renames remove the remote file from the `filter` to let it be transferred one more time on the next poll. The local file might be opened for processing, so this way we postpone a fresh remote file for the future poll rounds * Modify `copyFileToLocalDirectory()` to return `boolean` to reflect the fact of copy. This way we check the real number of transferred files **Cherry-pick to 4.3.x** Do not transfer remote file if we can't remove local one Polishing Log Messages
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
