update jenkins Updatecenter from CLI

gistfile1.txt

$ java -jar jenkins-cli.jar -s http://localhost:9000 install-plugin findbugs
findbugs is neither a valid file, URL, nor a plugin artifact name in the update center
No update center data is retrieved yet from: http://updates.jenkins-ci.org/update-center.json
findbugs looks like a short plugin name. Did you mean 'null'?


# Specifying a full URL works!
$  java -jar jenkins-cli.jar -s http://localhost:9020 install-plugin http://updates.jenkins-ci.org/download/plugins/AdaptivePlugin/0.1/AdaptivePlugin.hpi

# Get the update center ourself
$ wget -O default.js http://updates.jenkins-ci.org/update-center.json

# remove first and last line javascript wrapper
sed '1d;$d' default.js > default.json

# Now push it to the update URL
curl -X POST -H "Accept: application/json" -d @default.json http://localhost:9020/updateCenter/byId/default/postBack --verbose

If you go to https://updates.jenkins.io/, there are actually some helpful instructions on how to get the file and get it for your particular installed version of jenkins. That's important because new versions of plugins can be incompatible with the stable versions of jenkins.
