SelectorUtils.matchPath(): inconsistent behaviour on POSIX-like and Windows for single Wildcard pattern

[fishermans]

Hi,

I was wondering why maven-shade-plugin produces different results on Windows and MAC. The single wildcard match is working inconsistently depending on the OS.

Please find a test to reproduce this (see comments in test file):

import org.codehaus.plexus.util.SelectorUtils;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

public class PatternMatcherTest {

  @Test
  void testPatternMatchSingleWildCardLinux() {

    /* Passes on Linux - fails on Windows */
    Assertions.assertFalse(SelectorUtils.matchPath(
            "/com/test/*",
            "/com/test/test/hallo"));
  }


  @Test
  void testPatternMatchDoubleWildCardCaseInLinux() {

    /* OK */
    Assertions.assertTrue(SelectorUtils.matchPath(
            "/com/test/**",
            "/com/test/test/hallo"));
  }


  @Test
  void testPatternMatchDoubleWildCardLinux() {

    /* OK */
    Assertions.assertTrue(SelectorUtils.matchPath(
            "/com/test/**",
            "/com/test/test/hallo"));
  }


  @Test
  void testPatternMatchSingleWildCardWindows() {

    /* Fails on Linux - passes on Windows */
    Assertions.assertFalse(SelectorUtils.matchPath(
            "D:\\com\\test\\*",
            "D:\\com\\test\\test\\hallo"));
  }


  @Test
  void testPatternMatchDoubleWildCardWindows() {

    /* OK */
    Assertions.assertTrue(SelectorUtils.matchPath(
            "D:\\com\\test\\**",
            "D:\\com\\test\\test\\hallo"));
  }


  @Test
  void testPatternMatchSingleWildCardDotLinux() {

    /* Fails on Linux - fails on Windows */
    Assertions.assertFalse(SelectorUtils.matchPath(
            "com.test.*",
            "com.test.test.hallo"));
  }


  @Test
  void testPatternMatchDoubleWildCardDotLinux() {

    /* OK */
    Assertions.assertTrue(SelectorUtils.matchPath(
            "com.test.**",
            "com.test.test.hallo"));
  }
}
