> 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)
