how to place all jar files in one jar file?

is it possible to build a jar file made up of all jar files that I need? I am building my project and the jar files are not being included in the generated jar file and I would like to generate one separate jar file which contains all jar files in this project

You can use one jar maven plug in.

Not possible. You can't include jars in a jar in order to have them on the classpath (you can put them in the jar, but you can't use them as dependencies)

Maven, however, gives you an alternative with the maven-assembly-plugin. It unpacks all jars and stores their .class files in your new, single jar. There are, of course, other options to do the same thing, but maven is a great build tool to use anyway.

The yguard tool can do this. It can also shrink your code and obfuscate it if you wish.

Here is an ant example from their documentation:

  <taskdef name="yguard" classname="com.yworks.yguard.YGuardTask" classpath="buildlib/yguard.jar"/>

  <inoutpairs resources="auto">
    <fileset dir="${input-lib-dir}">
      <include name="myapp*.jar"/>
      <exclude name="*_obf.jar"/>
    </fileset>
    <mapper type="glob" from="*.jar" to="*_obf.jar"/>
  </inoutpairs>
