[build] Support Apple ARM64 Silicon (M1)

[kensipe]

Builds on Apple M1 machines fail based on lack of dependency support.

* What went wrong:
Execution failed for task ':jreleaser-tool-provider:compileJava'.
> Failed to calculate the value of task ':jreleaser-tool-provider:compileJava' property 'javaCompiler'.
   > Unable to download toolchain matching these requirements: {languageVersion=9, vendor=any, implementation=vendor-specific}
      > Unable to download toolchain. This might indicate that the combination (version, architecture, release/early access, ...) for the requested JDK is not available.
         > Could not read 'https://api.adoptopenjdk.net/v3/binary/latest/9/ga/mac/aarch64/jdk/hotspot/normal/adoptopenjdk' as it does not exist.

Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem (link to git repository is ideal)
• Full description of the issue provided (see below)

Steps to Reproduce

1. Buy an Apple MBP Pro / Max with Apple Silicon instead of your car or child's first year of tuition in college
2. Setup with Java 11 (support via Azul is pretty awesome: https://www.azul.com/downloads/?version=java-11-lts&os=macos&architecture=arm-64-bit&package=jdk)
3. Build: ./gradlew test

Expected Behaviour

Successful build

Actual Behaviour

Bad things

Environment Information

• Operating System: Mac OS Monterey 12.0.1
• JReleaser Version: Tip of Main
• JDK Version: Azul JDK 11

Please paste stacktraces from [out|build|target]/jreleaser/trace.log.

This is likely an upstream issue to resolve... Adding for awareness and prioritization.

@kensipe this is a problem when building JReleaser from source. The build requires Gradle 6.9 which is setup to work with Java 8 up to 15.

Do you need an osx-aarch64 build? we have one for the CLI ready for testing https://github.com/jreleaser/jreleaser/releases/tag/early-access

[aalmiray]

I see where the problem may be

jreleaser/apps/jreleaser-tool-provider/jreleaser-tool-provider.gradle

Lines 79 to 88 in 8a45256

	tasks.withType(JavaCompile) { JavaCompile c ->
	c.sourceCompatibility = JavaVersion.VERSION_1_9
	c.targetCompatibility = JavaVersion.VERSION_1_9
	}
	java {
	toolchain {
	languageVersion = JavaLanguageVersion.of(9)
	}
	}

This instructs Gradle to download Java 9 which uses AdoptOpenJDK by default. Perhaps it will be better to switch to Java 11 compatibility and use Azul as vendor.

great turn around! I was planning on jumping on the contribution train and was looking for a way to build it. But I also wanted to use the new Mac... thank you! that fix was too easy... no I hang my head in shame :) Great stuff! thanks again.

Thanks @kensipe, we've got plenty of opportunities for contributions. Specifically M1 support would be great given that I've yet to get my hands on one of those puppies.
