Directories created by Gradle showing up in /tmp

We’re seeing a large number of directories being created by Gradle in our /tmp dir on our Jenkins servers:

drwxr-xr-x 3 wasmgr wasgroup 4096 Mar 17 07:00 gradle3653686569603919263projectDir
drwxr-xr-x 3 wasmgr wasgroup 4096 Mar 17 07:00 gradle3873120841179297595projectDir
drwxr-xr-x 3 wasmgr wasgroup 4096 Mar 17 07:00 gradle703379869211695195projectDir
drwxr-xr-x 3 wasmgr wasgroup 4096 Mar 17 07:00 gradle5252982363028816831projectDir

We’re not sure what plugin may be creating these, but it is causing our /tmp space to fill up rather fast.

This is likely due to the use of ProjectBuilder. If you are using this in unit tests I suggest using a TemporaryFolder JUnit rule (or similar) as the project directory so that these get cleaned up properly. If not, we create a temporary directory for you, and while we use File.deleteOnExit() this in practice will only clean up the folder if it is empty.

Thanks Mark - so something like this (what I was doing before didn’t have the .withProjectDir())?

@Rule
TemporaryFolder tempFolder

def getProject(String rootProjectName, String... childProjects) {
  def projBuilder = ProjectBuilder.builder().withProjectDir(tempFolder.folder)
  def root = projBuilder.withName(rootProjectName).build()

  if (childProjects) {
    childProjects.each {
      def childProject = projBuilder.withName(it).withParent(root).build()
        childProject.projectDir.mkdirs()
      }
    }

  root
}

Yes, except you should be using tempFolder.root.
