I am refactoring a Legacy-Gradle project upgrading from 5.6.4 to 7.5.1. I did not include all projects yet, but I am getting the error

* What went wrong:
Out of memory. Java heap space

Possible solution:
 - Check the JVM memory arguments defined for the gradle process in:
   gradle.properties in project root directory

I don't know where this error comes from, but I suspect 3 things:

1. something changed between Gradle-versions
2. something is different between IntelliJ (current used IDE) and Eclipse (previously used IDE)
3. I messed up the project's Gradle structure

Any hint what I can do to find out what's going on? Is there another solution than giving more space in gradle.properties (I have already org.gradle.jvmargs=-Xmx4g and giving more feels like wrong in terms of scaling)? It seems like more tasks are running simoultaniously than before.

It seems like there was a bug with the checkstyle plugin (github.com/checkstyle/checkstyle/issues/10934). I switching from 9.2.1 to 9.3 and the error was gone.
