Exception (com.google.inject.CreationException) while activating nexus-repository-composer for Nexus v3.62.0-01

[BM-MD]

• What are you trying to do?

We have tried to install the plugin (v0.0.29) via (most) Permanent Install in our Nexus environment (v3.62.0-01). We used the .jar file available at The Central Repository.

Unfortunately, every time we restart Nexus, we get the following error in the log:

Any thoughts on this?

• What feature or behavior is this required for?

Activation/Use of the plugin.

I have no problems running the plugin (v0.0.29) with Nexus v3.62.0 on my side.
The only difference between us is that you use a jar, whereas I install via the kar.

I'd recommand you to use the kar installation, which is now recommended by Nexus, and much simpler than the jar installation ;)
(PS: the kar file contains the jar with all its dependencies and a config use by Nexus to load the plugin)

Just download it here : nexus-repository-composer-0.0.29-bundle.kar
Then put it in the deploy folder of your Nexus installation.
And that's all ! No more xml to modify !
