Description

Trying to export a runnable jar, where the main is in a groovy file. The Run Configuration is setup correctly and works.

When you export there is an error...

Jar export finished with problems. See details for additional infos.
Could not find main method from given launch configuration.

And the jar file has everything except the manifest does not have the main specified at all.

Interestingly if you let eclipse generate an ant script, then run the ant script it generates a runnable jar correctly.

How are you performing the export? I am able to export a groovy project to a jar file by right-clicking on the project -> Export... -> Jar File. And then I specify a name for the manifes.

I use Menu-File/Export Select Java/Runnable JAR FIle, Next> select the Runnable configuration, set the export destination, select Package required libraries into generated JAR click Finish, you get the Runnable JAR File Export dialog with the error.

However when I just tried it it worked! and produced a runnable Jar this time. So at the moment I cannot reproduce it, I have done a lot of work on the project since reporting this, but I don't know what would have fixed this.

Thanks

Thanks for getting back to me. I am tentatively closing this, but feel free to re-open if you experience this again. It would be helpful to have a failing project that I could work with.

I have exactly the same problem right now on eclipse... Generating an ant script and creating the JAR from it works. Interesting...

If you can explain how I can reliably reproduce, please re-open.
