Continue maven build after Error Prone error

[Chris Brown]

Hi All,

I'm using maven analyze projects with Error Prone but noticed that the build fails after one error is found and doesn't continue analyzing all the files. For example, I have a test project with multiple files all containing the exact same error (details below) but the build quits after just finding one. I have also tried mvn compile options (-fae,--fail-at-end and -fn,--fail-never) but still running into the same issue where it quits after one file. Is this expected and/or does anyone know how to use Maven to analyze every file in the project even after an EP error?



Output: $ mvn -q compile
/home/.../src/main/java/ShortSet.java:8: error: [CollectionIncompatibleType] Argument 'i - 1' should not be passed to this method; its type int is not compatible with its collection's type argument Short
      s.remove(i - 1);
              ^
    (see http://errorprone.info/bugpattern/CollectionIncompatibleType)

    Set<Short> s = new HashSet<Short>();

      s.add(i);
      s.remove(i - 1);
    }
    System.out.println(s.size());
  }
}

One route you can use is adding -XepAllErrorsAsWarnings as a <compilerArg> to the compilation and enable warnings. Then you can see all the output, fix them, and remove the argument to validate that you have them all.
