I’m running into a strange issue as I work to install a couple of custom plugins into the a NRM 3.20.0 instance running in Docker (specially the
sonatype/nexus3 image). Following the approach outlined in Installing Bundles, I can successfully install my first Kar manifest with no issues. Once I attempt to copy over my second Kar, I encounter the following:
nexus_1 | 2020-01-17 06:48:08,825+0000 WARN [fileinstall-/opt/sonatype/nexus/deploy] *SYSTEM org.apache.karaf.kar.internal.KarServiceImpl - Unable to install Kar feature nexus-blobstore-internal-custom/0.0.1 nexus_1 | java.lang.IllegalStateException: Resource has no uri nexus_1 | at org.apache.karaf.features.internal.service.Deployer.getBundleInputStream(Deployer.java:1633) nexus_1 | at org.apache.karaf.features.internal.service.Deployer.deploy(Deployer.java:898) nexus_1 | at org.apache.karaf.features.internal.service.FeaturesServiceImpl.doProvision(FeaturesServiceImpl.java:1062) nexus_1 | at org.apache.karaf.features.internal.service.FeaturesServiceImpl.lambda$doProvisionInThread$13(FeaturesServiceImpl.java:998) nexus_1 | at java.util.concurrent.FutureTask.run(FutureTask.java:266) nexus_1 | at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) nexus_1 | at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) nexus_1 | at java.lang.Thread.run(Thread.java:748)
My understanding is that plugins/bundles loaded under
/opt/sonatype/nexus/deploy are picked up by the running Karaf instance; however, attempting to load more than one consistently results in this exception.
I’ve been poking at this for far too long thinking that I may be missing something in my Pom file; however, things are quite similar to the built-in nexus-blobstore-s3 I’m referencing. I feel like this is a Karaf-ism that I do not understand.
A workaround is to update the
nexus/assemblies/nexus-core-feature manifest and inject the plugin as a “core feature” bypassing Karaf; however, that seems dirty and I would really like to better understand the issue being experienced.
Any thoughts? Is there any additional information that would help in diagnosing this?
