Plugin doesn't support parallel compilation
Is your feature request related to a problem? Please describe.
We want to build using Maven param 1.0C. But this plugin doesn't support threading.
Describe the solution you'd like
If it does support threading, the goal should be annotated to mention it. If not, the code should be fixed to support it. Since we have seen the plugin crash in parallel, some code needs to be fixed.
Describe alternatives you've considered
Run the report in a separate build that doesn't run in parall.
Additional context
Tested on 2.9.4 with -T 1.0C and about 12 modules. Java 21 and Maven 3.9.9.
Version 2.9.4 is quite outdated. The newest one is 3.8.1. Have you tried it with this one?
Indeed. I missed that the plugin was renamed. But trying with 3.8.1. However, you still have the threading warning. If it's supported, you should do @Mojo(name = "reporting", requiresProject = false, threadSafe = true). Looking quickly at the code in the mojo, it seems fine.
