JIRA: https://jira.spring.io/browse/INT-4054 Fixes GH-1833 (https://github.com/spring-projects/spring-integration/issues/1833) The `DefaultCandidate` pulled requirement for the `slf4j` dependency via its `Logger` and `LoggerFactory` usage. * Change `slf4j` to the standard Commons Logging * Exclude `slf4j` transitive dependencies from `optional` direct dependencies like `reactor` and `json-path` * Since they are `optional` it is safe to exclude their transitives to force our source code to be free from unexpected dependencies. Anyway they don't appear in the target application as a SI transitives and end-user is forced to pull them manually to switch on the desired features. If there is need in the `slf4j` for target application, it must be pulled manually as well. **Cherry-pick to 4.2.x**
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
