We are running jenkins via batch with jre 1.8.0_171. We set up in global tools the jdk from same version. In case we create a maven job and run them it will not find the jdk. The jobs configuration does not provide to configure jdk since we had only one configured. Workaround is to configure a second jdk that in job another than "System" could be configured. --> JDK configuration should be present also if only one JDK is in jenkins configured
