Cannot compile GWT project using com.google.gwt:2.10.0-new-groupid-2

I cannot reproduce, with either 3.8.4 (what I have locally), 3.8.5 or 3.6.3 (both from Docker). Can you share a reproducer?

From the stacktrace, it would probably mean there's some incompatibility between Plexus IO and Plexus Utils.
The call to setFilenameComparator was added 3 years ago and shipped in plexus-io 3.2.0: codehaus-plexus/plexus-io@bff7c5e (and hasn't changed since then)
Same for the method itself in plexus-utils, shipped in 3.3.0 and not changed since then: codehaus-plexus/plexus-utils@5e23866
This would mean you somehow have an older plexus-utils version.
Maven 3.6.3 indeed comes with plexus-utils 3.2.1, but somehow I cannot reproduce, which means that plexus-utils 3.4.1 from the plugin is being used.

Are you maybe not using the plugin's gwt-app packaging, and thus not using <extensions>true</extensions>, and that could possibly change the way Maven sets up class loaders?
A reproducer would greatly help.

Attached a reproducer. Thanks!

Just looking at the code before running it, I'd say this is likely due to:

          <dependencies>
            <!-- Code Server's Process Still Running After Stopping the maven launcher ( CTRL + C ) #110 -->
            <!-- https://github.com/tbroyer/gwt-maven-plugin/issues/110 -->
            <dependency>
              <groupId>org.codehaus.plexus</groupId>
              <artifactId>plexus-utils</artifactId>
              <version>3.0.16</version>
            </dependency>
          </dependencies>

Removed that dependency solved the problem. I suppose we can close this issue.
