  • I get the following error when trying to run a unit test. Example code is below. I was able to get past this error by including dependancy testCompile 'org.jvnet.hudson.main:hudson-core:1.159' but that then said other classes where missing. This doesn't see the correct path to go down anyway. *Error* {noformat} java.lang.NoClassDefFoundError: hudson/matrix/MatrixRun at com.inedo.TriggerBuildStepTest.<init>(TriggerBuildStepTest.java:13) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) ...
