Adding java to path does not work

[carlbalmer]

Setting and referencing a environment variable in the same withEnv() statement does not seem to work. This is used in lab-08 and all following labs.

Example:

node() {
    withEnv(["JABBA_HOME=/nal_hutta", "PATH+JABBA=${env.JABBA_HOME}"]) {
        stage('Build') {
            sh 'echo $PATH && echo $JABBA_HOME'
        }
    }
}
