=====

In this example, there are three subprojects called `shared`, `api`, and `person-service`:

1. The `person-service` subproject depends on the other two subprojects, `shared` and `api`.
2. The `api` subproject depends on the `shared` subproject.

We use the `:` separator to define a <<intro_multi_project_builds#sec:project_path,project path>> such as `services:person-service` or `:shared`.

	Shared     = flag.Bool("shared", false, "generate code that can be linked into a shared library")
	Dynlink    = flag.Bool("dynlink", false, "support references to Go symbols defined in other shared libraries")
	Linkshared = flag.Bool("linkshared", false, "generate code that will be linked against Go shared libraries")

        expect:
        emptyDir.assertDoesNotExist()

        when:
        def cache = new DefaultPersistentDirectoryCache(emptyDir, "<display-name>", properties, mode(FileLockManager.LockMode.Shared), initializationAction, cacheCleanup, lockManager, Mock(ExecutorFactory), buildOperationRunner)
        try {
            cache.open()
        } finally {
            cache.close()
        }

        then:
