Description

Reproduction steps

• Check out https://github.com/gradle/gradle/tree/lptr/groovy-4-bugs
• Run ./gradlew :ivy:compileAll, it works using 4.0.0-beta-1!
• Change the Groovy version here to `4.0.0-beta-2`: https://github.com/gradle/gradle/blob/860e74522dcbf2df635a27f38fef1daa0b093322/build-logic/dependency-modules/src/main/kotlin/gradlebuild/modules/extension/ExternalModulesExtension.kt#L23
• Run ./gradlew :ivy:compileAll

It fails with:

:ivy:compileTestFixturesGroovy FAILED	
Groovy compilation avoidance is an incubating feature.	
Executing Spock 2.0.0-groovy-3.0 with NOT compatible Groovy version 4.0.0-beta-2 due to set spock.iKnowWhatImDoing.disableGroovyVersionCheck system property. This is unsupported and may result in weird runtime errors!	
startup failed:
