Geb doesn't compile with Groovy5

[jkalq]

When using Geb with Groovy 5.0.0+, the geb-implicit-assertions AST transformation crashes at compile time with a NullPointerException originating from MetaClassImpl.getMetaProperty().

The root cause is Groovy 5 internally using ConcurrentHashMap, which does not permit null keys, resulting into any call to .get(null) throwing an NPE instead of returning null as it did in Groovy 4.

Can you test with 5.0.5? There were a few NPE-related fixes in that version.
It is currently out for voting (will be in maven central in under 24 hrs barring the finding of any major flaw).
The artifacts are here in the meantime: https://repository.apache.org/content/repositories/orgapachegroovy-1105

Confirming that with Groovy 5.0.5 we are not facing the compilation issue anymore.

Thanks for checking. I'll close. Please create a new issue if you spot any other problems.
