Find out reason for missing constraints in FUSE ESB 4.3.0
Hello,
I try to migrate some bundles from FUSE ESB 4.2 to FUSE ESB 4.3. Sadly it does not work out of the box, but I am confident that it should not be hard work!
Installing a bundle I was surprised about a new error message for unresolved constraints:
FUSE ESB 4.3
Error executing command: Unresolved constraint in bundle de.foobar.base.myBundle : Unable to resolve 179.0: missing requirement package; (&(package=de.foobar.arg)(version>=2.4.1.SNAPSHOT)) - package; (&(package=de.foobar.arg)(version>=2.4.1.SNAPSHOT))
Looking at this message it is hard to find out whats wrong! The same error forced in FUSE ESB 4.2 would bring up the message:
The bundle could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.log4j.helpers;version="0.0.0"
Here it is obvious what is missing!
So my question is: How to find out the reason for missing constraints in FUSE ESB 4.3. Are there maybe any new karaf analyzing possibilities (karaf commands)?
If the reason for a constraint problem is not reported explicit it would be hard to find these problems.
Thanks for help
Franz

This is my MANIFEST with fixed imports for the log4j packages (resolution:=optional) as the code referencing the missing log4j packages is not needed in my current use case.
