Hi Team,

I am trying to package the s3-cloud manager

I have to create a custom addon for nuxeo. To get some hands-on, I got the source code of cloudbinarymanager, which has the source code for different storage connecters.

I followed the steps written in the docs. From the terminal, I changed the directory to the project mentioned above and ran the command -

nuxeo bootstrap package

This create a module inside the project, where the add-on zip gets created after running the command -

mvn package

To install this add-on, using the command-

./nuxeoctl mp-install path/to/add/on/zip/file

It gets successfully installed, but the server doesn't start up.

The command ./nuxeoctl start tries to start the server for some time, but then gives up.
