[[sec:java-extension]]
== Contributed extension

The Java plugin adds the link:{groovyDslPath}/org.gradle.api.plugins.JavaPluginExtension.html[`java` extension] to the project.
This allows to configure a number of Java related properties inside a dedicated DSL block.

.Using the `java` extension to configure a toolchain
====

====

Note that `sourceSets` is a Gradle extension on `Project` of type `SourceSetContainer` and `java` is an extension on `Project` of type `JavaPluginExtension`.

==== Changes in the AbstractCodeQualityPlugin class

The deprecated `AbstractCodeQualityPlugin.getJavaPluginConvention()` method was removed in Gradle 8.0.
You should use `JavaPluginExtension` instead.

==== Remove implicit `--add-opens` for Gradle workers
