Like Thierry said, you can only do a full build. I just did that on tag “release-10.10-HF53” today. But it took me all day to make it work, because there are some issues and updates to the code have to be done. Briefly:

• missing dependency for a Nuxeo version of richfaces (-> add to module)
• Nuxeos maven repo now only supporting https (->update all pom.xml)
• github not allowing git: anymore (-> update all bower.json)
• I had issues with gulp when building some of the addons, so I just left the addons that are necessary for the minimum build.

Also you need a couple of dependencies. Mostly maven, python2 (!!), bower, grunt and gulp (<4.0)

After the build you are left with a zipped Nuxeo distribution which you can use with your nuxeo.conf. Or - guessing here - you could update the jars in your old installation with the new ones.

This is the script I came up with today

edit:

Be aware different hotfix versions, need other modules. I updated the script to work with HF59. Couldn't make it work for HF60 yet thou.

#!/bin/bash
# dependencies: mvn, bower, grunt, gulp
set -e

You can still do a full build of the 10.10 branch of Nuxeo, it should work even if you are not a customer (unless you had a problem with the NPM registry during your build ..)
