Allow concurrent builds

[ottlinger]

Thanks for the great plugin!

When I integrated it into our builds as follows:
$ versions:display-dependency-updates versions:plugin-updates-report enforcer:display-info -U -B -T8
I get the warning:

Can the plugin be made threadSafe by adding the annotation or are there things in the code that are not concurrently executable?

Thanks

This was fixed with #219, my installed version of 2.6-SNAPSHOT with Maven 3.5.2 doesn't output the warning.

I'm still getting this warning using Maven 3.5.4 and version 2.7 of the plugin. See:

* Your build is requesting parallel execution, but project      *
* contains the following plugin(s) that have goals not marked   *
* as @threadSafe to support parallel building.                  *
* While this /may/ work fine, please look for plugin updates    *
* and/or request plugins be made thread-safe.                   *
* If reporting an issue, report it against the plugin in        *
* question, not against maven-core                              *

Please don't reuse old issue better create a new one.. Also helpful would be how you called the versions plugin and also which version of the plugin you are using ?
