Get the resource directory in AEM

If you want to manipulate the files using Java then you can use relative paths instead and take advantage of ClassLoader.

e.g. to read a file test.json inside test-folder under src/main/resources and get its contents in Java code:

InputStream is = getStreamFromResources("test-folder/test.json");
printFileContents(is);

If not inside a folder:

InputStream is = getStreamFromResources("test.json");
printFileContents(is);

Methods:

private static void printFileContents(InputStream inputStream) throws IOException {
  StringBuilder textBuilder = new StringBuilder();
   try (Reader reader = new BufferedReader(new InputStreamReader
  (inputStream, Charset.forName(StandardCharsets.UTF_8.name())))) {
   int c = 0;
   while ((c = reader.read()) != -1) {
  textBuilder.append((char) c);
  }
  }
   jsonString = new String(textBuilder);
   LOGGER.info(textBuilder.toString());
}
// get file contents as stream from classpath, resources folder
private InputStream getStreamFromResources(String fileName) {
  ClassLoader classLoader = getClass().getClassLoader();
  InputStream is = classLoader.getResourceAsStream(fileName);
   if (is == null) {
   throw new IllegalArgumentException("file is not found!");
  } else {
   return is;
  }
}

This is how my folder structure looks like:
