Then it is a bootstrapping issue. You can solve it either using an older binary version of Groovy to build the new version of Groovy, or writing enough of a Groovy interpreter in Java that you can build your compiler with it.

Why is it hard to add to the build? Is it a bootstrapping issue?

right now we have 2 steps, build the compiler, then use the new compiler to build tests and runtime as well as modules. Since I need part of the runtime for the compiler in my case, it cannot work like this, unless enough of the runtime is Java to run the parts of the new compiler I am using. This should be the case, but can be trouble in the future.
