使用InteliJ在Maven项目中创建jar

Question

I'm all new to java and need to create an executable jar from InteliJ. It is a maven project and I don't really understand what I'm doing wrong. When creating the jar using right-click on src folder and choosing "Make Module" everything is ok and I can run it on the UNIX machine. BUT when I'm using the maven->Lifecycle->install I get an error:

 Exception in thread "main" java.lang.NoClassDefFoundError: taglib/Tagger
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:763)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    at Launcher.main(Launcher.java:10)

few more things: this project using another jar created with "install", when opening the pom.xml file I get the pom of the other project (stated before).

As I said I'm very new to all of this and especially maven and would like to understand.

Regards.

If its a maven project, you can simply create jar by using command mvn clean install from cmd, provided you have set your PATH variable properly. It will delete target directory and publish new jar there.
