Usage

From source file:org.apache.geode.BundledJarsJUnitTest.java

/**
 * Find all of the jars bundled with the project. Key is the name of the jar, value is the path.

private TreeMap<String, String> getBundledJars() {
    File geodeHomeDirectory = new File(GEODE_HOME);

    assertTrue("Please set the GEODE_HOME environment variable to the product installation directory.",
            geodeHomeDirectory.isDirectory());

    Collection<File> jars = FileUtils.listFiles(geodeHomeDirectory, new String[] { "jar" }, true);
