Newly appeared "Cannot resolve project dependencies"

[castortech]

I updated a few libraries for our project and started to use included target files (see separate discussion, but this issue occurred even if I reverted to a single target).

Here is what I got:

[WARNING] No solution found because the problem is unsatisfiable.:
   Unable to satisfy dependency from javax.xml.stream 1.0.1.v201004272200 to osgi.bundle; javax.xml 0.0.0.

[INFO] {osgi.os=linux, osgi.ws=gtk, org.eclipse.update.install.features=true, osgi.arch=x86_64, org.eclipse.update.install.sources=true}
[ERROR] Cannot resolve project dependencies:
[ERROR]   Software being installed: com.castortech.iris.ba.web.home 1.0.0.qualifier
[ERROR]   Missing requirement: org.osgi.service.jaxrs 1.0.1.202109301733 requires 'osgi.contract; (&(osgi.contract=JavaJAXRS)(version=2.1.0))' but it could not be found
[ERROR]   Cannot satisfy dependency: com.castortech.iris.ba.web.home 1.0.0.qualifier depends on: java.package; org.osgi.service.jaxrs.runtime 1.0.0

The "Unable to satisfy dependency" messages from above all existed in a previous successful build except for the one related to JAXRS.

In the IDE this build and runs fine. These libraries have not changed in many months and have build a hundred times at least. This capability is supplied via: <unit id="org.apache.aries.javax.jax.rs-api" version="1.0.4"/> which has:

Provide-Capability: osgi.contract;osgi.contract=JavaJAXRS;uses:="javax
 .ws.rs,javax.ws.rs.client,javax.ws.rs.container,javax.ws.rs.core,java
 x.ws.rs.ext,javax.ws.rs.sse";version:List<Version>="2.1,2,1.1"

At the end, I ended up manually removing the Require capability from org.osgi.service.jaxrs and it is now building.

Questions is why this just started now ? Why is it complaining that the capability is not resolved ? And how to debug this. I turned on debug and still can't figure it out at all or find any great information to pass on here.

Thanks
