Both `${languageLC.raw}-library-conventions` and `${languageLC.raw}-application-conventions` apply the `${languageLC.raw}-common-conventions` plugin *(1)* so that the configuration performed there is shared by library and application projects alike.
Next they apply the `java-library` or `application` plugin respectively *(2)* thus combining our common configuration logic with specifics for a library or application.

The shared _convention plugin_ `myproject.java-conventions` is implemented in an _included build_ called `build-conventions`.
The build is then included in the root project's _settings_ file as seen in the above snippet.
For more details about included builds, see link:{userManualPath}/composite_builds.html[Composing Builds] chapter.

The `myproject.java-conventions` plugin is then applied to the `buildSrc` build:
