How to add resource file to JAR in IntelliJ

Question

I am using IntelliJ IDEA 14 and I want to add file outside of src to the JAR file. This is my current project structure.

I want to add layout.txt and saveddata.txt to the JAR file executable. I've been googling on that for a while can't find the solution

In case you need to see my code. This is how I am reading file

private Path layoutPath = Paths.get("resources/layout.txt");
content = new String(Files.readAllBytes(layoutPath));

Here is my project structure

Answer 1

1. Create a folder called "resources" at the same level as "src"
2. Right click the folder, select "Mark Directory As -> Resources Root"

Still giving me NoSuchFileException. I marked it as Resource Root. – Dilorenzo

Presumably you mean your application is giving you an NSFE. Separate question if so, please post your code. General form is getClass().getResource("/path/image.png"). – Aurita

I have added the code. Can you check it again? Thanks :D – Dilorenzo

Try putting a "/" in front of the path and removing the folder "resources". The contents of your resources folder in the build is considered root, so your resource path would be "/layout.txt". – Aurita

I have tried putting in root directory. It doesn't add to the JAR file also – Dilorenzo

If it's not in the JAR, you're going to get a NSFE no matter what the name, but it needs to be "/layout.txt" for the location you provided. You probably need to set up your Artifacts in Project Settings and be sure "Build on make" is selected. – Aurita

from jetbrains; "During the build process, by default, the resources are copied into the root of the compilation output folder. If necessary, you can specify a different folder within that output folder." you need to follow this page for solution; jetbrains.com/help/idea/2016.1/… – Swindle

Answer 2

• Make new directory with name as "resources" under your project root directory.
• Right click on that directory and select "Mark Directory As" ==>"Resources Root" option.

Still giving me NoSuchFileException after I have rebuilded – Dilorenzo

@Renges : The code is using a relative path, which makes it depend on the current working directory of the JVM that launches the tests. A more reliable way to read resource files is 'getClass().getClassLoader().getResourceAsStream()', or, if necessary, 'getClass().getClassLoader().getResource()'. In a J2EE environment you'd typically use 'Thread.currentThread().getContextClassLoader().getResourceAsStream()'. – Ceramist

@Ranjeet, I think that getClassLoader().getResourceAsStream is the right way to go. May you please edit your answer and elaborate? thanks. – Beerbohm

Answer 3

For me, the resources directory was already marked as Resources Root but the content was missing in the jar. I had to manually add the resources dir to the jar artifact using the Project Structure window.

1. Open Project Structures window
2. Select Artifacts and click on the + button and then select Directory Content
3. Choose resources directory
4. Press Apply then OK

Answer 4

It's still for me. I tried:

+ "Mark Directory As" ==>"Resources Root"
+ getClassLoader().getResourceAsStream()
+ getClass().getClassLoader().getResource()
and Thread.currentThread().getContextClassLoader().getResourceAsStream()
