Validate plug-ins: Missing Constraint on bundle [message #1716220]

Dear experts,

I am developing an RCP application:

-- I have a feature-based product P which includes my feature F.
-- feature F wraps bundle B1
-- B1 depends on B2

When I run P, I get the usual "No application id has been found" but I am used to this, and I usually use the Add Required Plug-ins button in my Run Configuration and I'm OK.

Now time has come to deploy the application and I'm facing troubles.
Troubleshooting my issues, I realised that if I validate my plug-ins in my Run Configuration, I get this:

Missing Constraint: Require Bundle: B2; bundle-version="0.0.0"

Indeed it does not get included automatically in my Run Configuration, although it is declared as a bundle dependency in B1's MANIFEST (Require-Bundle directive).

This is indeed the problem I am facing while launching my deployed executable.

The question is: Why U NO include B2??
Ok.. seriously: any idea?

Thank you very much,
-Piero

It is a feature based product and if I understand correctly B2 is not part of your feature. So question back: Why do you expect that B2 is part of your product if you haven't added it to your product via feature?

Thanks Dirk.

Exactly B2 is not part of F, but I thought that dependencies at bundle-level where not ignored. Indeed I realized that it is necessary to include features including B2 in the feature.xml file.

Side note:
In case B2 is not included in any feature (eg. an external library), I manually copied B2.jar inside B1 (+added to classpath +exported). Is this THE way to go in such cases?

Now, despite the validation of the dependencies does not detect anything wrong, I see that the magic button "Add Required Plug-ins" in my Run configuration is still adding more plugins.
How can I detect and include in my product all these new required plug-ins without a brute-force diff of my run configurations?
What is THE way here as well?

Thanks

There is another magic button called Validate that inspects your configuration and tells you what is missing.

Dear Dirk,

Now, despite the validation of the dependencies does not detect anything wrong

indeed validation does not detect missing requirements, but then plug-ins are still added when I click on Add Required.

Furthermore, when no existing feature includes a given packaged plug-in, should I manually import the jar file in my bundle or is there some other more orthodox way to achieve that?
