How to download a Runnable version of JEMM ?

🚀 Not a Developer? No Problem!

If you're not into coding or just want to skip the hassle of building JEMM from source, we've got you covered! You can directly download the ready-to-run file:

jemm_runnable-jar-with-dependencies.jar

To run it smoothly, make sure:

  • 🧩 You have Java 11 installed on your machine.
  • 🔑 You’ve generated an API Key from your Jellyfin instance. Check the doc about Jellyfin API Key
  • 🛠️ Having trouble? Before diving into fixes, make sure to check the Requirements Page It covers everything JEMM needs to run smoothly and can help resolve common setup issues quickly.

To download source-code and build JEMM Locally

🛠️ If you're a developer, you can clone the JEMM project using your favorite Git client:

git clone https://github.com/CesarBianchi/JellyfinEasyMetadataManager.git

JEMM was originally built using Apache NetBeans IDE 19 and Java 11, but feel free to use any IDE you're comfortable with — like IntelliJ IDEA, Eclipse, or VS Code.

Once cloned:

  • Import the project into your IDE as a Maven project.
  • Make sure Java 11 is set as your runtime environment.
  • Build the project using Maven (mvn clean install) to generate the runnable .jar file.
  • Run JEMM using the generated jemm_runnable-jar-with-dependencies.jar located in root/target/.

Happy coding! 💻
