Although IntelliJ IDEA has en excellent Maven integration, it doesn not recognize file references or file links in the output of Maven commands. One such generator of file links is checkstyle which generates an output like this:
Now our live would be a lot easier, if we could just click on the message to fix the issue. Luckily, with a litte hack, this is possible: IntelliJ provides a possibility to define custom output filters for “External Tools“. Therefore navigate to “Preferences > Tools > External Tools“. Add a new one with “mvn” as command and “validate” or whatever triggers checkstyle as parameter.
Then click on “Output Filters” and a a Filter with an arbitrary name and “$FILE_PATH$:$LINE$(:$COLUMN$)?.*” as Regular Expression.
If you now choose “Tools -> External Tools -> Checkstyle” Maven will run again producing a nicely linked output:
