getClass().getResource(“/”) returns null in command line

Question

I\'m trying to read a file in my maven project at /src/main/resources/file.txt.

I\'m using

URL url=this.getClass().getResource(\"/\");
String filePa         


        

Answer 1

There are (often) no directories inside jar files. Therefor it will return null.

If you want to get the file you could get that resource directly:

URL fileUrl = getClass().getResource("/file.txt");
...

Or simply:

InputStream fileInputStream = getClass().getResourceAsStream("/file.txt");

Answer 2

You should move that file into your CLASSPATH and get it like this:

InputStream is = this.getClass().getResourceAsStream("file.txt");
