    • Windows 10, Jenkins 2.0-beta-1, JDK 1.8.0_77

      I run Jenkins 2.0 beta binary under Windows 10.
      I declared a Maven installation "M3" under Global Tool Configuration.
      I created the pipeline job with the following script:

      node {
  git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'
  def mvnHome = tool 'M3'
  bat "${mvnHome}\\bin\\mvn -B verify"
}

      I get the following error when installing Maven:

      Workaround: I have to declare explicitely JAVA_HOME environment variable in Manage Jenkins -> Configure System -> Global properties section. I set it to "C:\Program Files\Java\jdk1.8.0_77"
      After that the build works correctly

      Clearly I think on Global Tool Configuration, a Maven installation should be bind to a JDK installation to avoid such issue. Concretely in Maven widget a combobox should be present to select a JDK installation already configured above.

          Why not have Jenkins also install Java?

          Is Java on your PATH?

          Straightforward workaround present, therefore reducing priority.

          Also, could probably define JDK installations (with a defined path, doesn't need to be auto-installed), and reference those in the pipeline.

          On Global Tool Configuration, I add a new JDK installation called "JDK-1.8".
          I set the JAVA_HOME field under installation name to C:\Program Files\Java\jdk1.8.0_77 and run the job again -> same result JAVA_HOME is not found.

          What happens when you call tool 'JDK-1.8' in your pipeline?

          I did this as it :

          node {
  git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'
  def mvnHome = tool 'M3'
  tool 'JDK-1.8'
  bat "\"${mvnHome}\"\\bin\\mvn -B verify"
}

          I still get the error:

          If i explicitely set JAVA_HOME, it works

          node {
  git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'
  def mvnHome = tool 'M3'
  env.JAVA_HOME = tool 'JDK-1.8'
  bat "\"${mvnHome}\"\\bin\\mvn -B verify"
