==== Toolchain-based tasks for JVM projects

Starting with Gradle 8.0, all core Java tasks that have toolchain support are now using toolchains unconditionally.
If `JavaBasePlugin` is applied, the convention value for tool properties on the task is defined by the toolchain configured on the `java` extension.
In case no toolchains are explicitly configured, the toolchain corresponding to the JVM running Gradle is used.

	// toolchain you can download and run. In that case fall back to at least
	// checking that the toolchain is new enough for the Go version.
	toolchain := "go" + old
	if wf.Toolchain != nil {
		toolchain = wf.Toolchain.Name
	}
	if gover.IsLang(gover.Local()) {
		toolchain = gover.ToolchainMax(toolchain, "go"+goVers)
	} else {
		toolchain = gover.ToolchainMax(toolchain, "go"+gover.Local())
	}

=== Defining tool chains

The supported tool chain types are:

* link:{groovyDslPath}/org.gradle.nativeplatform.toolchain.Gcc.html[Gcc]
* link:{groovyDslPath}/org.gradle.nativeplatform.toolchain.Clang.html[Clang]
* link:{groovyDslPath}/org.gradle.nativeplatform.toolchain.VisualCpp.html[VisualCpp]

=== Example: Defining tool chains

[source.multi-language-sample,groovy]
.build.gradle

====

The Kotlin DSL Plugin leverages <<toolchains#toolchains,Java Toolchains>>.
By default the code will target Java 8.
You can change that by defining a Java toolchain to be used by the project:
