Adding resources in IntelliJ for Maven project

Question

I have a project structure like this:

src  |-main     |-java        |-com.abc.xyz           |-Login.java 

I have to add a resource file to this and read the resource with

InputStream is = getClass().getResourceAsStream("launchers.properties"); 

This is giving null.

In Intellij I am not able to add a new package under src/main for resources folder so that the project structure looks like this. How can I load the launchers.properties resource file into the project?

src  |-main     |-java        |-com.abc.xyz           |-Login.java     |-resources        |-com.abc.xyz           |-Login              |-launcher.properties 

I tried the solution suggested by @maba but still not working

Answer 1

The launcher.properties should not be under a folder called Login. It should be placed directly in the src/main/resources/com/abc/xyz folder.

It is really as simple as I said but if the resources folder is not marked as a sources folder then this may be the problem.

This is the initial class and setup:

Now create the resources folder:

This newly created folder should be automatically marked as a sources folder and if it is blue color marked then it is. Otherwise you'll have to mark it manually:

Now you'll be able to add packages to it:

And now you can add the file to it:

And rerunning the application will not give you any null value back:

And the package view will surely show the launchers.properties file as well:

Answer 2

As @maba pointed out, your properties file should be in the same package as your class for your code to work.

So, you should have two files:

• src/main/java/com/abc/xyz/Login.java
• src/main/resources/com/abc/xyz/launcher.properties

If IntelliJ is showing the resource or not is beside the question. What you need to do is check if the results are included in your target artefact.

Do a build all in IntelliJ, open up the resulting WAR/JAR/EAR with your favorite ZIP viewer and browse into the "com/abc/xyz" folder. You should see both files there.

• If they are, you are doing something wrong in your code. Check for typos, especially dots and spaces at the end or beginning (e.g. "launcher.properties[space]"), copy/paste the file name to make sure
• If they are not there, your IntelliJ setup is wrong. Resources do not get included in your target build. Check online for tutorials how to do this with IntelliJ idea.
