FilePath.installIfNecessaryFrom介绍

[英]Given a tgz/zip file, extracts it to the given target directory, if necessary.

This method is a convenience method designed for installing a binary package to a location that supports upgrade and downgrade. Specifically,

  • If the target directory doesn't exist #mkdirs().
  • The timestamp of the .tgz file is left in the installation directory upon extraction.
  • If the timestamp left in the directory doesn't match with the timestamp of the current archive file, the directory contents will be discarded and the archive file will be re-extracted.
  • If the connection is refused but the target directory already exists, it is left alone.
