Version 4.13.0 has been released. This plugin should be updated.

Some people still use this plugin for testing grammars-v4. Please update the pom.xml with a new version 1.23, and publish to Maven Central, like it was done previously. 9981c93. Thanks.

Any update on this issue? I face the same error with the plugin runtime is different from the one being generated.

This plugin is no longer the primary method for testing in grammars-g4, so it doesn't matter whether it is updated. The plugin only works with the Java target. Do you require this plugin or https://www.antlr.org/api/maven-plugin/latest/usage.html? They are different.
