      Description

      After adding a test project to my repository, I started getting the below error during the build when updating android project files.

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

      I tracked down the error which appears to be a misuse of the String.split function in plugins/android_emulator/util/Utils.java:616.

      // Target directory is somewhere above our directory
      String[] fromParts = fromPath.substring(1).split(File.separator);
      final int fromLength = fromParts.length;
      String[] toParts = toPath.substring(1).split(File.separator);
      final int toLength = toParts.length;

      File.separator is a string but String.split is expecting a regex. On windows, File.separator is an invalid regex.
