问题
I am trying to build a p2 repository using Tycho and the tycho-p2-repository-plugin in an eclipse-repository packaging type. When I run the build, it is giving me the following exception:
Failed to execute goal org.eclipse.tycho:tycho-p2-repository-plugin:0.13.0:assemble-repository (default-assemble-repository) on project com.mycompany: No content specified for p2 repository
Can someone point me to the cause of this problem?
回答1:
You need either of the following files in the root of the eclipse-repository project:
- A
category.xmlfiles with at least one feature referenced in it - A
*.productfile
These files define what should be included in the p2 repository, so if there is none of these, the p2 repository would be empty. This is probably not what you wanted, so Tycho fails the build. (Admittedly, the error message could be more helpful...)

I had this problem too, unfortunately it was one of many problems and I do not remember which thing I did to fix it.
Make sure you are using 0.14.1 of tycho.
My working version is a very empty pom.xml, much like Packaging Types
I have not needed to configure the eclipse-repository via tycho-p2-repository-plugin.
Do you have a valid target definition defined in your reactor build somewhere? Is your *.product file valid? The product file needs to be in the same directory as your eclipse-repository pom, I think it gets found via black magic.
Also make sure your product feature is separate from your eclipse-repository. under PDE builds you could have the *.product file and the with the feature that is the root for your product.
