Eclipse Export Product not possible

Question

I tried to make a headless Eclipse RCP because I want to launch it through a C file with JNI. I created a plug-in project, set the correct settings in MANIFEST.MF and created Headless.product. Everything works, also Application.java, but when I tried to export the .product to have the executable file, it gave me an error. So I tried with an existing project from this tutorial (just in case the problem wasn't in the settings) and it gave me the same error:

 Cannot complete the install because one or more required items could not be found.
 Software being installed: Headless Example 0.0.0 
 (com.codeandme.headless.headless 0.0.0)
 Missing requirement for filter properties ~= $0: Headless Example 
 0.0.0 (com.codeandme.headless.headless 0.0.0) requires 
 'com.codeandme.headless.headless_root.gtk.linux.x86_64 [1.0.0]' but 
 it could not be found

This is the screenshot of the problem

(Where com.codeandme.headless is the name of the project)

Now, what should I do to make the export possible? Anything to do with org.eclipse.equinox.executable ? And if yes, where and how can I add it?

Thank you in advance for your help :)

Answer 1

I had the same error message:

Missing requirement for filter properties ~= $0: Application 0.0.0 (org.acme.project.application 0.0.0) requires  'org.acme.project.other 1.2.3' but  it could not be found

For some reason this error (also) means, that org.acme.project.other is present... twice.

So in your case, open the "Content" tab of the "Target Editor" and make sure that com.codeandme.headless.headless_root.gtk.linux.x86_64 is not present in two distinct versions. This bundle might be inside a feature, so it might be a bit hard to find where the second version came from.
