As long as soureSets are named "mainXX", with XX a feature version, we check everything automatically:
- ECJ is disabled (we can't do a check without forking ECJ as a separate process using toolkit, we may support this later)
- forbiddenapis (we disable checks for missing classes)
- errorprone is disabled (errorprone does not work correctly at moment with forked compiler)
This uses Gradle's auto-provisioning to compile Java 19 classes and build a multi-release JAR from them. Please make sure to regenerate gradle.properties (delete it) or change "org.gradle.java.installations.auto-download" to "true"
LUCENE-10185 caused a large performance regression in ECJ tasks by using the --release flag.
Instead of using --release, we can just disable "terminal deprecation", and leave this check to `javac`. The --release flag makes this tool run 50% slower.
* LUCENE-10185: pass --release 11 to ECJ linter, fix JDK 17 build
Otherwise, new java releases such as JDK 18, JDK 19, ... may have even
more new deprecations, the build shouldn't fail in such cases.
Remove -source/-target now that we pass --release
Fix casting so ECJ understands it and creates correct call signature (UweSays: "It's ok. I know why it happens, but it's a bug in ECJ. The type safety is checked by the invokeexact")
