https://github.com/apache/flink/pull/3190
> The ´${project.build.directory}` is not automatically cleaned up.
The/tmp` directory is natural to clean up.
hi, Stephan, thank for your reply.
When restarting os, tmp dir will be clean up automatically. And
´${project.build.directory}/tmp` will be clean up when executing `mvn clean`.
IMO, `${project.build.directory}` target dir can avoid multiple users building
projects to share the same `/tmp` problem thoroughly.
In another word, I think project building's boundary is its target
directory. Beyond target dir should be not reasonable. Keep project building
independent.
In addition, correct all the temporary creating style with
`TemporaryFolder` and add random dir prefix, that will modify more test file.
Maybe we can resolve the `TemporaryFolder` problem in another thread.
Thanks
Happy New Year!
