I recently upgraded a slew of Jenkins plugins all in one go (bad idea I know!) and when it came to running my job pipelines again I encountered many Invalid parameter errors.

An example of the stacktrace can be seen below:


org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: WorkflowScript: 16: Invalid parameter "execPattern", did you mean "path"? @ line 16, column 19. execPattern: 'target/jacoco.exec', ^

WorkflowScript: 17: Invalid parameter "classPattern", did you mean "path"? @ line 17, column 19. classPattern: 'target/classes', ^

WorkflowScript: 18: Invalid parameter "sourcePattern", did you mean "path"? @ line 18, column 19. sourcePattern: 'src/main/java', ^

WorkflowScript: 19: Invalid parameter "exclusionPattern", did you mean "path"? @ line 19, column 19. exclusionPattern: 'src/test*' ^

4 errors

The error messages aren’t particularly informative but do seem to indicate that the parameters I was setting in the jacoco reporting plugin no longer exist or are invalid for the plugin.

I suspect it is linked to this issue - JENKINS-55436 where a plugin that has duplicate named steps to another plugin will prevent the other plugin from parsing correctly.
This would make a lot of sense and would present similarly, based on this I concluded another code coverage plugin is probably clashing with Jacoco as they would have similar requirements as far as parameters go; include pattern, exclude pattern etc.

Removing the following plugins solved the issue:
