The following are equivalent when _run from the root project_:

----
$ gradle :subproject:taskName
----

----
$ gradle subproject:taskName
----

You can also run a task for _all_ subprojects using a task _selector_ that consists of only the task name.

The following command runs the `test` task for all subprojects when invoked from the _root project directory_:

----
$ gradle test
----

tch(s){throw this.handleError(s,t.proxyOf)}if(t.type!=="root"&&t.type!=="document"&&!t.parent)return!0;if(Sr(a))throw this.getAsyncError()}}runOnRoot(e){this.result.lastPlugin=e;try{if(typeof e=="object"&&e.Once){if(this.result.root.type==="document"){let t=this.result.root.nodes.map(r=>e.Once(r,this.helpers));return Sr(t[0])?Promise.all(t):t}return e.Once(this.result.root,this.helpers)}else if(typeof e=="function")return e(this.result.root,this.result)}catch(t){throw this.handleError(t)}}getAsyncError(){throw...

Suppose you want to use a path relative to the _root project_ directory. In that case, you need to use the special link:{groovyDslPath}/org.gradle.api.Project.html#org.gradle.api.Project:rootDir[Project.getRootDir()] property to construct an absolute path, like so:

	configName := baseName[0 : len(baseName)-len(configType)]
	if configType != "" {
		configType = configType[1:]
	}
