Producing executable jar in NetBeans

Question

I\'m using NetBeans 6.5 and for some reason it won\'t produce executable jar \"out of the box\".

I set my project to be the main project, defined main class in the p

Answer 1

I had the experience, that the build process is different, depending on the project type.

I suppose, you've created "Java Class Library" project.

So just create a "Java Application" project, then merge all classes to it.

Then, Netbeans will not override, but enhance the "manifest.mf" into the JAR.

Of course, it's a stupid Netbeans bug. Of course it should be possible to add main classes afterwards.

EDIT: Please see my other answer. It's easier.

Answer 2

Maybe you created Java Project with Existing Sources instead of Java Application?

I had similar problem and creating new Java Application and then manually copying src files solved the problem - everything worked "out of the box".

Answer 3

If you are using the maven assembly plugin and want to build an executable jar with dependencies, you need to add this portion to the configuration of the maven-assembly-plugin section in your pom.xml:

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <!-- ... -->
    <archive>
      <manifest>
        <mainClass>your.app.SampleClass</mainClass>
      </manifest>
    </archive>
  </configuration>
</plugin>

Goto the Files view. Create a manifest.mf in the root directory.

/project_folder
    build.xml
    manifest.mf(edit here)
    /dist
    /src
    /test
    /build
