eclipse exported product could not resolve org.eclipse.core.runtime while “launch application” does work

问题

Developing an eclipse plugin based application. In the product, when I push "Launch an Eclipse application", the application runs correctly. When I export the application and try to start it, i get org.eclipse.core.runtime is not resolved. Yes, in dependencies I did an "add required plug-ins". What should I do in order to have a working product exported?

here is the current development tree: https://github.com/magwas/zenta/tree/export_bugreport You can find the product file in org.rulez.magwas.zenta.editor.build/zenta.product, and the exported product in tmp/Zenta.eclipse

I have one entry in start level configuration: org.eclipse.core.runtime autoStart="true" startLevel="0"

Here is the log of the failed launch:

回答1:

It looks like your start level configuration in the .product file is wrong (this is on the Configuration tab in the Start Levels section in the .product editor).

For a straightforward RCP you don't need to specify the levels so just clear this.
