Test coverage report aggregator maven plugin does not work with maven 3.9.x

[tim-boerner]

I am using the test coverage report aggregator maven plugin in our project and it was working fine with maven 3.6.1 and 3.8.8. Now I have updated to maven 3.9.5 and the aggregate goal fails with following error:

Hi @tim-boerner,

I recently had the same effect on another project. It turns out that a newer maven version brings in other versions for plugin dependencies.

After fixing all plugins by providing a dedicated version, my build was successful again. As you have all maven versions at hand, could you please check the versions of the plugins and provide more details about the version changes?

The version numbers are printed in the output.

I updated the plugin versions of compiler, surefire and failsafe plugin but i still get this error

[tim-boerner]

I think here is the reason: https://cwiki.apache.org/confluence/display/MAVEN/Notes+For+Maven+3.9.x+Plugin+Developers

The org.codehaus.plexus:plexus-utils artifact is not anymore "auto injected" (auto provided) to plugins classpath

@tim-boerner You're right. With Maven 3.9.0 this behavior was changed. Currently looking at the best way to fix this. And also looking at the best practices from site you mentioned.

I had the same problem with the 3.9.7 version.

[rohwerj]

@AleksaMCode But that problem is now solved with the most current version correct?

[AleksaMCode]

@rohwerj I'm not sure, perhaps. I've solved my issue by downgrading to 3.8.8.
