Support jvmTarget 17

[eygraber]

Currently setting it to 17 results in Invalid value passed to --jvm-target

It seems like the issue is that I tried doing this in an included build. It works fine otherwise. Not sure why it doesn't work in included builds, but I'm guessing it's not a detekt issue.

This project has a buildSrc that works fine with jvmTarget = "17" but the included build doesn't.

I just ran into this issue in another project that tries to use jvmTarget = "17" for a regular module, but it doesn't work (Invalid value passed to --jvm-target).

Maybe there is something going on here?

Here's my config:

detekt {
  toolVersion = libs.versions.detekt.get()

  source.from("build.gradle.kts")

  autoCorrect = true
  parallel = true

  buildUponDefaultConfig = true

  config = project.files("${project.rootDir}/detekt.yml")
}

tasks.withType<Detekt>().configureEach {
  // Target version of the generated JVM bytecode. It is used for type resolution.
  jvmTarget = libs.versions.jdk.get()
}

Kotlin 1.5.3X seems to support up to Java 16 as the target: https://github.com/JetBrains/kotlin/blob/1.5.30/compiler/config.jvm/src/org/jetbrains/kotlin/config/JvmTarget.kt.

I see that JVM_17 was added in Kotlin 1.6.0, so hopefully this is unblocked by #4277

I've manually tested, and yes, #4277 should fix the issue. This issue will be closed when that PR is merged.

Working workaround:

dependencies {
    detekt("io.gitlab.arturbosch.detekt:detekt-cli:1.19.0")
    detekt("org.jetbrains.kotlin:kotlin-compiler-embeddable:1.6.0")
}

This is still happening sporadically in 1.20.0-RC2

Maybe related to detekt getting set up in a Gradle precompiled script plugin, which uses Kotlin 1.5.31

Looks like the issue is that the snapshots aren't updated since November.

Not sure what you refer to, but the last snapshot was published today:
https://oss.sonatype.org/content/repositories/snapshots/io/gitlab/arturbosch/detekt/

Ah I was looking at a different view of the snapshot repo.

Well then this is still an issue. Like I said above:
