           single: Set this option to 'single' if your patch branch contains changes
             for any option that can't work on master/base branch
           online: Set this option to 'online' if you want to download
             the PMD report of master/base branch rather than generating it locally
           local: Default option is 'local', PMD reports for the base and patch branches are generated locally.
 
-    -t, --threads          Sets the number of threads used by PMD. Set threads to 0 to disable multi-threading processing. default:1
-    -f, --html-flag        whether to not generate the html diff report in single mode
-    -a, --auto-gen-config  whether to generate configurations automatically based on branch differences,this option only works in online and local mode
-    --keep-reports         whether to keep old reports and skip running PMD again if possible
-    -d, --debug            whether change log level to DEBUG to see more information
-    --error-recovery       enable error recovery mode when executing PMD. Might help to analyze errors.
