osgi.ee require cap with strange version spoils bundle resolution

[Matteo Rulli]

Hello,

I just upgraded a bundle to a newer version (akka-http v. 10.0.11) and the resolver is complaining with the following error:

 (default-cli) on project resolve.akka-http: Unable to resolve <<INITIAL>> version=null: missing requirement com.typesafe.akka.http [caused by: Unable to resolve com.typesafe.akka.http version=10.0.11: missing requirement akka.http.impl.engine.rendering; version=[10.0.11,10.1.0) [caused by: Unable to resolve com.typesafe.akka.http.core version=10.0.11: missing requirement akka.parboiled2.support; version=[10.0.11,10.1.0) [caused by: Unable to resolve com.typesafe.akka.parsing version=10.0.11: missing requirement &(osgi.ee=JavaSE)(version=1.8.0_144)]]] -> [Help 1]

 The manifest of the akka-http bundle actually contains this:

 Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8.0_144))"

 which seems a little bit odd as a version: I'm not even sure it is well formed, is it?

 How can I solve the problem? I tried with this in the bndrun file:

 -runsystemcapabilities = osgi.ee;osgi.ee=JavaSE;version:List<Version>="1.8,1.8.0_144"

 But I get

 [ERROR] Failed to execute goal biz.aQute.bnd:bnd-export-maven-plugin:3.5.0:export (default-cli) on project resolve.akka-http: java.lang.IllegalArgumentException: Invalid syntax for version: 1.8.0_144

Is wrapping the akka-http bundle and getting rid of the odd require-cap the only approach?

Thanks,

Matteo

The bundle is in error. One, the version is not a valid OSGi version: 1.8.0_144 and, two, that is too precise a version number anyway since a framework implementation will just offer 1.8 for Java 8 or 9 for Java 9.

That bundle needs to be fixed.

I would be interested to know if there is a way to fix that without repackaging the 3rd party bundle ?

You could try

-runsystemcapabilities = osgi.ee;osgi.ee=JavaSE;version:List<String>="1.8,1.8.0_144"

That is, use String instead version for the List type. Then it wont be parsed as a version and so wont barf. But then all filter compares are just string compares, so normal version comparison wont happen. That is, 1.8 != 1.8.0.
