Nexus can’t startup due NullInjectedIntoNonNullable on RemovedAssetSender.java:48

post by iseki on Jul 22, 2022

I’m trying to develop an integration. But after installing my bundle, the Nexus can’t startup.

I found the following error report in the nexus.log:

After that, all things failed. I found lots of errors such as java.lang.ClassNotFoundException: org.sonatype.nexus.repository.RepositoryTaskSupport not found by com.sonatype.nexus.plugins.nexus-repository-npm [323]

I’m the beginner of plugin development. If you have any idea for it, please let me know. Thank you

I’m afraid I don’t really have a suggestion for you. It would seem something your bundle does is affecting the availability of the standard Nexus bundles.

The problem is solved. It’s because something which is not OSGi-ready is bundled. Change the bundle settings and inline the dependencies in the main jar to avoid unexpected effects on Nexus.

Can you explain more what you did here? I am facing the same issues. Is it in the nexus-bundle import/export package settings I need to change things?

My solution: Bundle all dependencies except nexus related into a single jar, and don’t mention them in the import/export settings.(Because they may not be OSGi ready.)
