Hi, since I just got that mail with JDK21 coming along I thought I try to run Groovy with it - fully expecting gradle to fail already. And of course
Caused by: BUG! exception in phase 'semantic analysis' in source unit './build-logic/src/main/groovy/org/apache/groovy/gradle/CheckstyleHtmlReport.groovy' Unsupported class file major version 65 That is basically not surprising but I was wondering... why is it actually the case? Should we not be able to compile with a target class file version for the build? From the home page for Gradle 8.1.1: """ With toolchain support added to GroovyCompile, it is possible to compile Groovy code using a different Java version than the one running Gradle. If you also have Java source files, this will also configure JavaCompile to use the right Java compiler is used, as can be seen in the Java plugin documentation. """ There is actually 2 things I would like to have. One is to be able to use for example JDK21 for Groovy compilation, but with 16 (or something we support) as target. And the other is to be able to additionally use a different JDK version to run Gradle itself. What do you guys think? bye Jochen
