Maven - Manifest file and Jar with Dependencies

Updated: Nov 23, 2021

In this post, we will build a simple maven project which will create two jar files, which can be executed using below command

java -jar sample.jar <arguments space separated>

In maven, there is plugin called maven-assembly-plugin, which will assemble the dependencies and package it into a jar file, provided packaging as jar is given in the maven pom.xml file.

So, first and foremost thing is to have packaging given as jar like this


Now in the build section, add the maven-assembly-plugin like this


This will create a manifest file in your jar file with the Main class given as com.Main and will create a new jar file with jar-with-dependencies as suffix. This new jar will have more size as compared to the normal jar file, because if your project happens to have any dependencies, it will be included into this jar file.

Now you can run the

java -jar mavenManifestJarDep-1.0-SNAPSHOT.jar <arguments space separated>

You can refer this on Github Link for the sample pom.xml file and the target directory for the jar files and their sizes.

  • mavenMainfestJarDep-1.0-SNAPSHOT.jar, &

  • mavenMainfestJarDep-1.0-SNAPSHOT-jar-with-dependencies.jar
