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 project properties "run" menu and it works flawlessly when I press F6 to run it.
I looked at the manifest file and it indeed didn't define the main class there, and also omitted the library dependencies.
Am I missing something? Is there a way (other than manually altering the manifest file) to produce executable jar files?
EDIT: yes, I tried clean and rebuild and it produced the jar in the dist folder, still with the same manifest.mf
Manifest-Version: 1.0

I just had the same problem in NetBeans 7.2.1 with a Maven Java Application project. Modify the pom.xml file to include the maven assembly plugin with one tweak to myrho's answer (needs to reference the predefined descriptor "jar-with-dependencies"):
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>your.app.MainClass</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
An alternate method is to build a Java Application project in NetBeans that doesn't use Maven. Select File -> Project Properties -> Build -> Packaging and check the "Copy Dependent Libraries" checkbox.
