How to build JARs from IntelliJ IDEA properly?


I have a project that contains a single module, and some dependencies. I'd like to create a JAR, 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's "build JAR" 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 runnable.

    Select Extract to the target Jar

    Click OK

    Click Apply/OK

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

    Build -> Build Artifact -> Build

    Try Extracting the .jar file from:

    📦ProjectName
     â”— đź“‚out
       â”— đź“‚artifacts
         â”— đź“‚ProjectName_jar
            â”— đź“śProjectName.jar
