Hi we are facing the same problem.
Are there any workarounds ?

[CasperNLD]

Hi, will there be a java 17 release in the near future?

[jdillon]

The stack here suggests its the Groovy runtime that isn't supporting the newer bytecode, is there a problem including a newer Groovy version by GMaven?

[sreich]

any updates on this? or workarounds...impacting a migration to java 17 on my end

[jdillon]

I could use an example project showing this failure. Locally I don't have issues with Java 17 execution of Groovy code via the groovy-maven-plugin.

[sreich]

I attempted but I'm struggling to reproduce this myself on a new sample project, and unfortunately can't share my entire project/library setup. I might deprioritize this given other stuff on my plate, sorry wish I was more help here

[volkanistek]

I solved the issue with adding dependency of groovy to gmaven instead of using gmaven version

<plugin>
