Jenkins- build fail with java.lang.NoClassDefFoundError: jenkins/mvn/GlobalMavenConfig
jenkins
Solution
In general, `NoClassDefFoundError`in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time.
You may take a look at javadoc and great blog post.
It seems that version of maven-plugin in in `<Full path to jenkins.war>/WEB-INF/plugins` is newer than version of jenkins-core in `<Full path to jenkins.war>/WEB-INF/lib` and jenkins/mvn/GlobalMavenConfig was added in 1.515, so your maven-plugin version may be >= 1.515 and jenkins-core version may be < 1.515. Perhaps, you either followed steps that are mentioned here or there is something wrong with your jenkins.war.
How to verify it:
Check jenkins version and also `jenkins-core-<your version>.jar`. You may found `jenkins-core-<your version>.jar` in `<Path to jenkins.war>/WEB-INF/lib/` folder. Classes for maven-plugin are in `<Path to jenkins.war>/WEB-INF/plugins/maven-plugin/WEB-INF/lib/classes.jar`. Maven-plugin version mentioned in `<Path to jenkins.war>/WEB-INF/plugins/maven-plugin/META-INF/MANIFEST.MF`.
How to fix it:
You may install latest version of jenkins or at least install correct maven-plugin.
