How can I resolve require-capability?

[Christian Eugster]

Hi
I am putting together an osgi enterprise framework from aries, because I want to use it in an eclipse rcp application. I am collecting the bundles from aries for the jndi, jpa, proxy, quiesce, transaction and util modules and their dependencies. For checking I run the framework like java -jar org.eclipse.osgi_3.13.0.v20180409-1500.jar -console

the collected bundles so far are:

As you can see, I have two persistence api bundles (67, 74).

The bundles 64, 63, and 62 are not resolved due to missing Require-Capability. I searched the web for information about osgi.contract and require-capability (provide-capability), but to be honest, I do not really understand the concept, though it should simplify the dependency management. What am I to do to resolve the following requirements?


g! diag 64                                                                                                   10:58:49
org.apache.aries.jpa.eclipselink.adapter [64]
  Unresolved requirement: Require-Capability: osgi.contract; filter:="(&(osgi.contract=JavaJPA)(|(version=2)(version=2.1))(!(version>=2.2)))"

g! diag 63                                                                                                   10:59:05
org.apache.aries.jpa.container [63]
  Unresolved requirement: Require-Capability: osgi.contract; filter:="(&(osgi.contract=JavaJPA)(|(version=2)(version=2.1))(!(version>=2.2)))"

g! diag 62                                                                                                   10:59:20
org.apache.aries.jpa.api [62]
  Unresolved requirement: Require-Capability: osgi.contract; osgi.contract="JavaJPA"; filter:="(&(osgi.contract=JavaJPA)(version=2.0.0))"

Thank you
