Karaf / OSGI Bundles error in debug mode

[Charles Moulliard]

Hi,

When I try to debug a openengsb unit test within intellij, I get after unresolved errors contraints when karaf container 2.3.0 is started :

- Version used of openengsb : 0.5.1

- Config : 

    public static Option[] getDefaultKarafOptions() {

        Option[] options =

                // Set the karaf environment with some customer configuration

                new Option[]{

                        karafDistributionConfiguration()

                                .frameworkUrl(maven().groupId("org.apache.karaf").artifactId("apache-karaf").type("tar.gz").version("2.3.0"))

                                .karafVersion("2.3.0")

                                .name("Apache Karaf")

                                .useDeployFolder(false).unpackDirectory(new File("target/paxexam/unpack/")),

                        KarafDistributionOption.keepRuntimeFolder(),

                        logLevel(LogLevelOption.LogLevel.INFO)

Error :

Is there a workaround ?

Hey Charles,

1) JB and I have merged paxexam-karaf into Karaf itself (starting from Karaf 2.3.0; https://search.maven.org/#artifactdetails%7Corg.apache.karaf.tooling.exam%7Corg.apache.karaf.tooling.exam.options%7C2.3.0%7Cbundle)

2) I cant remember to have seen "org.osgi.framework.BundleException: Exported package names cannot be zero length." before... BUT if I would have to do a wild guess I would say there's a problem with the paths in intellij. Can you please create an issue in the Karaf Jira? I'll try to reproduce the situation locally.

Kind regards,

Andreas
