JIRA: https://jira.spring.io/browse/INT-3383 The family of Message.(set|get)Properties methods has been factored out of Smack as an extra extension. Use JivePropertiesManager as replacement. It is no longer necessary to supress Smack path warnings. Delete custom smack-config.xml, as all it did was disabling certain (important) SASL mechanisms. Also remove the unit test that verified this. Some unit tests mock ChatManager and Chat for no reason, delete those lines. XMPPConnection.getHost() and .getPort() are only valid after the connection got established, due the fact that those information is often only available after a DNS SRV lookup was performed. Remove the lines in unit tests that verified their value. Remove the truststorePath example in documentation, since Smack 4.0 no longer provides support for providing a custom truststore. Instead ConnectionConfiguration in Smack 4.0 allows to set a custom SSLContext (which then again can provide a TrustManager that uses a custom truststore).
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
