Hi guys,

error: java.util.regex.PatternSyntaxException :: Unexpected internal error near index 1

I've checked on github project, and I've found the origin of the bug:

private String _getGradlePath(Path path, Path basePath) {
    Path relativePath = basePath.relativize(path);

    String gradlePath = ":" + relativePath.toString();

    [b]gradlePath = gradlePath.replaceAll(File.separator, ":");[/b]

    return gradlePath;
}

The replaceAll method takes a regular expression as input, that on windows fails because File.separator = "\"
the solution is to "escape" the input string:

private String _getGradlePath(Path path, Path basePath) {
    Path relativePath = basePath.relativize(path);

    String gradlePath = ":" + relativePath.toString();

    gradlePath = gradlePath.replaceAll([b]Matcher.quoteReplacement(File.separator)[/b], ":");

    return gradlePath;
}

Could you help me to submit this issue to JIRA?
