Get a list of resources from classpath directory

Question

I am looking for a way to get a list of all resource names from a given classpath directory, something like a method List getResourceNames (String direct

Answer 1

Based on @rob 's information above, I created the implementation which I am releasing to the public domain:

private static List getClasspathEntriesByPath(String path) throws IOException {
    InputStream is = Main.class.getClassLoader().getResourceAsStream(path);

    StringBuilder sb = new StringBuilder();
    while (is.available()>0) {
        byte[] buffer = new byte[1024];
        sb.append(new String(buffer, Charset.defaultCharset()));
    }

    return Arrays
            .asList(sb.toString().split("\n"))          // Convert StringBuilder to individual lines
            .stream()                                   // Stream the list
            .filter(line -> line.trim().length()>0)     // Filter out empty lines
            .collect(Collectors.toList());              // Collect remaining lines into a List again
}

While I would not have expected getResourcesAsStream to work like that on a directory, it really does and it works well.
