ERROR: [JENKINS-18403] JDK 5 not supported to run Maven

Here is what I am doing:

  1. Jenkins (v.1638) master runs on Windows 7
  2. A node/slave (agent) runs on Linux (Ubuntu 14.04)
  3. JDK 6 (Oracle jdk1.6.0_45) is used
  4. Maven 2.2.1 is used

Next message is partially copied from console output when I kick off project build:

[webapp] $ /usr/local/jdk1.6.0_45/bin/java -cp /projects/maven-agent.jar:/projects/classworlds.jar hudson.maven.agent.Main /usr/local/apache-maven-2.2.1 /projects/slave.jar /projects/maven-interceptor.jar 58848 /projects/maven2.1-interceptor.jar

I got confused by the output:

  1. my Linux doesn't have JDK 5. Why does Jenkins report this error?
  2. why are maven agent run twice? one by jdk1.6.0_45 and one by jdk1.7.0_79
  3. jdk1.7.0_79 is configured in the field of JavaPath of Node (for running slave agent in Linux). why is it picked up to execute maven agent?

I am newbie to Jenkins and couldn't find answers to my questions.

Please explain why it works this way. I appreciate it very much for your help.

Jenkins starting with version 1.612 needs JDK 7 to run. Furthermore Maven 2.2.1 is not supported anymore by Jenkins (as far as i knwo). Furthermore Maven 2.2.1 is End Of Life. – khmarbaise
I understand Jenkins itself runs on JDK 7 (or above, actually it runs on JDK 8 by default) but doesn't mean project can't be built by Maven 2 on JDK 6. – Wayne
Ok. Now you are asking something different. Ok Jenkins runs with JDK 8 which means by default Maven 2 will run with JDK 8 as well. If you need to support JDK 6 you need to configure to use Maven toolchain. Furthermore sometimes it is better to use freestyle project in Jenkins instead of Maven Project type... – khmarbaise
