I had the same issue and the solution in #278 fixed the problem. if you are using a repo and your current pom inherits from the pom defining the plugin be sure to push your parent pom to remote and then do a mvn -U clean to ensure the pom being analyzed gets the update with the specific asm version that resolves the issue
