Description

It was suggested I open an issue here as well. I am a user of groovy so do not know a lot of the details that could help diagnose. I would be happy to gather them if told what was required.

We are upgrading a large Grails app with 400+ controllers, 550+ services, 350 domains, 4000 files with 950k loc to Grails 4.1.0.M1 + Gradle 5.6.4.

Using Gradle 5.6.4 with Java 8 & Grails 4.0.3(Groovy 2.5) a clean/groovyCompile took approximately 5 minutes.

 

Using Gradle 5.6.4 with Java 11 & Grails 4.1.0.M1(Groovy 3.0.4) a clean/groovyCompile takes 33 minutes on a 2019 MBP w/ 2.4 GHz 8-Core Intel Core i9 & 64gb of RAM.

I have tried giving the groovyCompile task 16/32gb of ram, with no noticeable change. I've also tried -Dgroovy.antlr4=false - but this gave other compile time errors I did not see with it set to true (so was unable to have a full successful compile)
