I have created a separate manifest file like this one. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.

JAR files support a wide range of functionality, including electronic signing, version control, package sealing, and others. What gives a JAR file this versatility? The answer is the JAR file's manifest. The manifest is a special file that can contain information about the files packaged in a JAR file. Select the Manifest file you just added to your project.

Make sure the Manifest has the path to your Main class e. For example this is how a basic Manifest file would look like:. My above method works well. A manifest is a simple text file, Sun's tutorial describes its contents in detail. All you have to do is create such a file and update the JAR files with this command:. With Ant you can use jar task. It has a manifest option to specify all the attributes yo need to include.

Something like this:. A default manifest file is created when you create a jar using jar cf jar-file inputs-files. Manifest files are text files. This doesn't work for signed JARs, of course. Also you can take a look at this documentation, this helped me to solve the issue using the Eclipse wizard.

See Eclipse Documentation. Browse to your Main class and click Finish. This generates the manifest WITH the main class information allowing the jar file to be executed. Find centralized, trusted content and collaborate around the technologies you use most.

I exported my project using the Export as Runnable Jar option in Eclipse, which worked perfectly fine originally. However, I now have a splash image that I need to include in the manifest for the Runnable jar, which cannot be specified when exporting as a Runnable Jar. So, I tried to do Export as a Jar and just set the manifest manually through there. It allows me to set the manifest, but another problem arises.

If someone could tell me a method where I could export the project as a runnable jar with a custom manifest and the extraction of required libraries into the jar, I would highly appreciate it. I first acted as if I wanted to create a runnable jar by right clicking my project, clicking export, and clicking runnable jar.

Then, I exported it as a runnable jar but also checked to get the ant build script to my desktop. In the generated build. Now, to use this new build script to export the project, right-click the project file, go to properties, go to builders, click New Choose the location of the modified build file you exported for the Buildfile, and choose the project folder as the base directory for the Base Directory.

To run the necessary ant configuration, click the arrow next to the button to the right of the green play button that looks like this:. Add the Ant Build configuration previously made, or if it doesn't show up, add it using the previous steps.
