Packaging Java SE application with weld into executable Jar

Question

I Got the following exception while trying to run JAVA SE executable jar from command line:

However I'am able to run the program sucessfully in eclipse but once packaged into jar I always end up with this error.

Here is my maven package plugin:

     <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>

        </executions>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
      </plugin>

      <!-- Build an executable JAR -->

          </manifest>
        </archive>
      </configuration>
    </plugin>
    </plugins>

and here is how I bootstrap Weld:

public  static void main(String[] args) {
    //Start CDI container
    WeldContainer weldContainer = WeldFactory.INSTANCE.getWeldContainer();

    try {
        MainThread mainExecutor = weldContainer.instance().select(MainThread.class).get(); 
        mainExecutor.run();
    } catch (Exception e) {
        LOG.error("Fatal error",e);
    }finally {
        //Shutdwon CDI container
        weldContainer.shutdown();   
    }

}

//  @Inject
//  MainThread mainExecutor;
//  
//    public void main(@Observes ContainerInitialized event){
//      try {
//          //MainThread mainExecutor = weldContainer.instance().select(MainThread.class).get(); 
//          mainExecutor.run();
//      } catch (Exception e) {
//          LOG.error("Fatal error",e);
//      }finally {
//          //Shutdwon CDI container
//          //weldContainer.shutdown(); 
//      }
//
//    }

(I've tried both commented and uncommented code but still getting the same error). Any help will be great, I've really tried all things.

User Siliarus has helped you, kudos for him.

Now you have encountered another problem. App shutdowns immediately.
It's not strange - that's happens because you don't make use of the ContainerInitialized event. If you are using the built-in org.jboss.weld.environment.se.StartMain class, then you should have a simple bean which observes the ContainerInitialized event.

Alternatively, you can make use of the Main class, which content you've pasted above. To do this, instruct a maven-jar-plugin to use your shiny class with a main method with something like this:

<mainClass>com.your.own.class.with.main.method</mainClass>

In case of another problems, I encourage you to take a look at the working examples of Weld's usage: https://github.com/weld/core/tree/master/examples.

Hope it helps.
