Jenkins / Maven: Could not resolve default JAVA_HOME path, Build failing

I’ve got a problem regarding Java Builds in Jenkins.

The Error I resolve is the following one:

  • How to remotely login to a Jenkins server using Java?
  • Why is jGit's RevWalk.reset() method misbehaving?
  • Using readClassDescriptor() and maybe resolveClass() to permit Serialization versioning
  • How to create a patch in IntelliJ IDEA?
  • Error - trustAnchors parameter must be non-empty
  • Google Code and Eclipse Update Site
  • Unable to locate the Javac Compiler in:
    Please ensure you are using JDK 1.4 or above and
    not a JRE (the class is required).
    In most cases you can change the location of your Java
    installation by setting the JAVA_HOME environment variable.

    I got JDK1.6 and JDK1.7 projects, so I need two JDK installations. For my default Java JDK I used the 1.6 for the JAVA_HOME variable, which points to C:\Program Files\Java\jdk1.6.0_45. Same for the 1.7 version, but in a separated variable (JAVA_HOME7).
    The PATH variable contains the appended \bin to the two JDK versions.

    In Jenkins I also added both versions for JDK and as helper variables.
    If I am setting a concrete version for a project (e.g. JDK1.7), then it’s building without any issues. Unfortunately I’ve got a lot of build-projects, so it would be time consuming to set this manually.

    I don’t understand where the call or variable for the path of the error C:\Jenkins\jre\..\lib\tools.jar is set and where I can modify it…

    Jenkins Version: 1.509.4

    Any hints or advices how to solve this problem?

  • How am I supposed to work with multi-module Maven projects with EGit?
  • SparseCheckout in Jenkinsfile pipeline
  • When do I commit when moving files in a git? (Jgit)
  • Jenkins git-client: how to move to jgit on windows
  • Jenkins HTML Publisher Plugin 1.3 gives 404 error
  • Hudson / Jenkins: share parameters between several jobs
  • One Solution collect form web for “Jenkins / Maven: Could not resolve default JAVA_HOME path, Build failing”

    I faced the same problem. The below steps solved the problem

    1) Go to Manage Jenkins – Configure system

    2) Add JAVA_HOME and its path in Global Properties – Environment Variables

    3) Add JDK and path in JDK section
