Maven packaging project as executuble JAR with dependencies

Question

I'm new to Maven and having difficulties packaging my java project as a executable Jar. The program compiles and works correctly when I run it from the IDE (IntelliJ).

I have the following pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </plugins>
    </build>



</project>

The target directory looks like this:

However, when I run the application from terminal I get:

mathan:target Mathan$ java -jar AlgorithmicDebugger-0.1.jar

    Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/jdi/IncompatibleThreadStateException
        at com.mathanv.Main.main(Main.java:15)
    Caused by: java.lang.ClassNotFoundException: com.sun.jdi.IncompatibleThreadStateException

I thought it may have been the project not finding tools.jar? but it is inside the dependency folder I created.

Answer 1

Used One-JAR to build all dependencies into one executable JAR.
