[yukiisbored]

The tests are failing which is blocking PRs and further contributions to this project. A fix or temporary workaround is needed before GCI.

@yukiisbored I'm a newcomer and just opened a PR in this repo. Just wanted to know if there's any progress on this.

@manankalra Hey, very little progress is made due to time constraints. I'm gonna unassign myself from this.

[manankalra]

@yukiisbored I can take this issue if you can guide me a little on what needs to be done. :)

I want to try and fix this... can you assign this to me? @yukiisbored

#51 is likely to be helpful to find and fix this bug.

The getAvailableBears method shown below runs coala -B --json which must be throwing error because of this issue: coala/coala#4881

public static JSONArray getAvailableBears() throws ExecuteException, IOException {
    CommandLine cmdLine = new CommandLine("coala");
    cmdLine.addArgument("--json");
    cmdLine.addArgument("-B");
    final ByteArrayOutputStream stdout = new ByteArrayOutputStream();
    PumpStreamHandler pumpStreamHandler = new PumpStreamHandler(stdout, null);
    Executor executor = new DefaultExecutor();
    executor.setStreamHandler(pumpStreamHandler);
    executor.execute(cmdLine);
    JSONArray bearList = new JSONObject(stdout.toString()).getJSONArray("bears");
    return bearList;
  }
