'How to get source code directory in Gradle plugin?

I want to get the directory of Java files in a Groovy plugin.

For example, I have a Java file in a directory:

"/gradleProject/src/main/java/com/file.java"

How can I get:

"src/main/java"

In Maven there is Build.getSourceDirectory(), what is the equivalent in Gradle?

gradle

Further to Rene's answer, the groovy DSL makes it easy to get the SourceSet

SourceSet mainSourceSet = project.sourceSets.main

In java this is a little bit more verbose

SourceSet mainSourceSet = project.getConvention().getPlugin(JavaPluginConvention.class).getSourceSets().getByName("main");

In Gradle, those source folders are managed by SourceSets, that are brought to you by the Java plugin. The java plugin adds two sourceSets named main and test.

once the java plugin is applied, you can access those sourceSets and their properties (e.g. the folders you're looking) simply by name: project.sourceSets.main.srcDirs - this will give you all the configured source directories for the main sourceSet in your project.

The latest way to do this, using the Kotlin DSL:

val javaExt = project.extensions.getByType(JavaPluginExtension::class.java)
val mainJavaSource = javaExt.sourceSets.getByName(SourceSet.MAIN_SOURCE_SET_NAME)
