            I have installed 1.612 but it broke one build, so I reverted to 1.611

            Our Jenkins uses Java 1.8, the slave uses 1.7, but the broken build is a Maven project that depends on Java 1.6. In the job configuration the JDK is set to 1.6 and I tried the optional maven parameter -Dmaven.compiler.executable=/opt/java/jdk-1.6/bin/javac. In 1.612 I get a line in the console output which says "JENKINS-18403] JDK 5 not supported to run Maven" ... but I didn't specify JDK5, also restarting the build slaves didn't help.

            I applaud the upgrade to Java7 and I would like to upgrade our projects to Java7 or Java8, but some legacy code makes it complicated.

            jgeertsma see JENKINS-25272. You must now set the job configuration to JDK 7 or higher. The message is just out of date; what is not supported to run Maven is any version of Java older than what the Jenkins master itself requires.

            After upgrading to Jenkins 1.612, we can no longer build Java 1.6 Maven projects. We get this "JENKINS-18403 JDK 5 not supported...." error, followed by compilation errors related to API changes from Java 1.6 to Java 1.7.

            If I understand the discussion in JENKINS-25272 correctly, this is deliberate behavior. Jenkins will no longer allow us to have multiple maven projects which build using different JDKs. There are two workarounds: either upgrade all of our projects to Java 1.7, or stop using the Maven Project Type, using a Freestyle project type with Maven Build Step instead.

            Is this understanding correct? Does Jenkins 1.612 no longer support the building of Java 1.6 Maven projects? If so, we will probably just continue using older versions of Jenkins for the foreseeable future.

            If you wish to use the Maven project type, you must set the Jenkins project configuration to use JDK 7 or newer, which means the JVM used to run Maven itself. The JDK tools used to build and test your project’s code may be anything. These tools are defined by settings in Maven plugins, such as -Dmaven.compiler.executable=… on the Maven command line.

            Alternately, you can simply build your project using JDK 7+ tools but using tool configuration limiting the source code to earlier releases (such as -source 6), and using the Animal Sniffer plugin to block Java 7+ APIs from being used accidentally.

            If you wish to run the Maven process using anything older than Java 7, you must use the freestyle project type with the Maven build step—which I would strongly recommend for a variety of reasons anyway.

            We have some older slaves which run SunOS-5.9 for which Oracle does not provide Java7. Slave upgrade is not a solution either since there are some native legacy tools used in the build system which can only run on this machine. Does this mean I will have to stop upgrading Jenkins in order to have SunOS-5.9 slaves connected?

            Sounds that way, unless you can find an OpenJDK 7 port.

            Jesse, why would you strongly recommend to use the freestyle project type for Maven builds?

            I tried to look at it but there is two different build step available: invoke maven3 and invoke maven goal (or something like that, I am not using the english locale).
            Which one should then be used?
            And are dependencies taken into account to trigger the jobs as with the maven project type?
            Is there specific to do w.r.t. to the tests and the unstability of the build?

            Thank you for your help
