JAVA: including files in jar and how to access them

Question

I need to include some image files in the exported jar file, I searched a bit and found this and this answers but I can't get it to work.

so my file structure is:

root
-assets
--clean.png
-src
...

I added the assets folder to the build path as suggested but if I unzip the jar the files are not in the assets folder but in the root.

I tried the following codes:

InputStream i = getClass().getResourceAsStream("assets/clean.png");
InputStream i = getClass().getResourceAsStream("/assets/clean.png");
InputStream i = getClass().getResourceAsStream("clean.png");
InputStream i = getClass().getResourceAsStream("/clean.png");

but they none of them work, i is null. What I'm missing?

I'm using Maven

Do you use Maven ? Did you unzip your JAR to check if your resources were actually included ? — Mickael, Jun 27 '16 at 10:02
https://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html. Your resources must be in src/main/resources. — JB Nizet, Jun 27 '16 at 10:11

You should add your files into Maven resource directory src/main/resources or src/test/resources for tests.
