Select the strategy that should be used to store the affected source code files. Storing the affected source code files along with the issues consumes a lot of space on your hard disk for large projects. So if your server has not enough free space available to store the sources for all builds, it might make more sense to store only the sources of the last build. In this case, the plugin will automatically discard old results before the new sources are stored. If you do not need the source files at all, you can deactivate the storing of source code files. The following options are supported:

NEVER
  Never store source code files.
LAST_BUILD
  Store source code files of the last build, delete older artifacts.
EVERY_BUILD
  Store source code files for all builds, never delete those files automatically.
MODIFIED
  Store only changed source code files for all builds, never delete those files automatically.
