Set the Java and Kotlin bytecode targets #458

Closed JakeWharton closed 1 year ago

JakeWharton commented 1 year ago

Otherwise the running JDK version is used, which is sometimes unsupported (e.g., today with JDK 20).

This is copied from the convention plugin which applies to the normal modules, but it also needs to happen in the buildSrc which is a separate Gradle build.

Today, with JDK 20, you get:

> Task :buildSrc:compileKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':buildSrc:compileKotlin'.
> Error while evaluating property 'compilerOptions.jvmTarget' of task ':buildSrc:compileKotlin'.
   > Failed to calculate the value of property 'jvmTarget'.
      > Unknown Kotlin JVM target: 20

* Try:
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
