Is the SonarQube Java analyser supposed to be able

Question

Given the following java source code,

public class Test {
  private static int a;
  private static int a;
}

you will run into an error while analyzing, is it expected? I think it should be log as a parser failure, not to stop the analysis, right?

Answer 1

This source code can't be compiled and so we also don't expect the SonarQube Java analyser to be able to analyse this piece of code. But the error message should be a bit more meaningful. I've created the following Jira ticket: http://jira.sonarsource.com/browse/SONARJAVA-1182
