Install Eclipse plugin - "no repository found at jar"

I am trying to install a plugin I wrote.

Using Eclipse Add/Remove Software, I am using the "Add Archive" and choosing the zip file I just distributed.

(Plugin written and tested in eclipse-RPC and I try to install on MyEclipse)

During the installation I get: "no repository fo开发者_JAVA技巧und at jar" error.

Any clue?

Please post the contents of the file, e.g. it's file and folder structure.

It seems that the ZIP file is not in the format of an Archived Update Site. The ZIP file should contain the following items in the root:

plugins/
features/
site.xml
artifacts.xml
contents.xml
