maven user library not packaged in my runnable jar

Question

I'm now programming Java for a year and had to take over several projects from a previous programmer. I'm not a programming newby since I started with .NET programming in 1998. Now for a Java project, I need to support 24 versions (and rising) of a base library (all the same structure but they are specific for a version of the 3th party application). I started with Maven two days ago and tried this on a small demo workspace in order to learn Maven and get the required things working. Each supported version has several jars which I encapsulated in a user library. To make a build, I would need to modify this library to the correct version and do an export of the project as a Runnable-Jar (everything include in the jar due to license requirements). So I created my first POM and here it is:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </pluginRepository>
    </pluginRepositories>
</project>

As you can see, I have two profiles. One for v8.1 and one for v7.0.

My 'build' flow: I run 'mvn install' on the libraryProject first. Then I run 'mvn package' on the main project. This one build v8.1 (Default profile) as a runnable jar with all depencies in it except the user library. The next call is 'mvn package -PPPC_7.0' which builds v7.0 without the user library.

So my question: What can I change/doing wrong so the user library is added to the runnable jar for each profile?

Thanks in advance,
Jo

PS: I'm using Eclipse Luna (Java EE IDE)

Answer 1

What I use is:

 <build>

<plugins>

  <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <mainClass>com.clouway.App</mainClass>
        </manifest>
      </archive>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
    <executions>
      <execution>
        <id>make-my-jar-with-dependencies</id>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

</plugins>

`

Good luck!

Answer 2

Robby Cornelissen commented a suggestion a while back:
Any chance of just packaging that up and using it as a dependency? That would definitely solve your problem... – Robby Cornelissen Jun 11 at 8:52

I didn't want to do that, but I did not receive new suggestions (and did not find a solution myself). So I packaged them as suggested and added them as dependency.

This is working for me now.

Thanks and until next time
