How can I build JAR files from IntelliJ IDEA properly?

I have a project that contains a single module, and some dependencies.

I'd like to create a JAR file, in a separate directory, that contains the compiled module. In addition, I would like to have the dependencies present beside my module.

No matter how I twist IntelliJ IDEA's "build JAR" file process, the output of my module appears empty (besides a META-INF file).

Solution

  • Instructions:

    File → Project Structure → Project Settings → Artifacts → Click + (plus sign) → Jar → From modules with dependencies...

    Select a Main Class (the one with main() method) if you need to make the JAR file runnable.

    Select Extract to the target Jar

    Click OK

    Click Apply/OK

    The above sets the "skeleton" to where the JAR file will be saved to. To actually build and save it do the following:

    Build → Build Artifact → Build

    Try Extracting the .jar file from:

    📦ProjectName
 ┗ 📂out
   ┗ 📂artifacts
     ┗ 📂ProjectName_jar
        ┗ 📜ProjectName.jar
