[[sec:antlr_source_set_properties]]
== Source set properties

The ANTLR plugin adds the following properties to each source set in the project.

`antlr.srcDirs` — `Set<File>`::
The source directories containing the ANTLR grammar files of this source set.
Can set using anything <<working_with_files.adoc#sec:specifying_multiple_files, that implicitly converts to a file collection>>.
