Basically I have imported an external plugin to my E4 application, now when I try to run it using the command in the product tab "Launch an eclipse application" it fails because of Missing Constraints.
Instead, if I go thru "Run Configuration" -> "Plugins" -> "Add Required Plugin" -> "RUN" It works like a charm.
I also tried to import, as dependencies of my MANIFEST file, the missing libraries but I always get the same problem.
Example of missing constraint:
org.osgi.framework.BundleException: Could not resolve module: com.telespazio.optsat.wizard.xygraph [961]
