Via the link:https://code.google.com/apis/console/?noredirect[API Console] the
Gerrit maintainers have access to the `Gerrit Code Review` project.
This projects host several buckets for storing Gerrit artifacts:

* `gerrit-api`:
+
Bucket to store the Gerrit Extension API Jar and the Gerrit Plugin API
Jar.

* `gerrit-maven`:
+
Bucket to store Gerrit Subproject Artifacts (e.g. `gwtjsonrpc` etc.).

[[deploy-configuration-settings-xml]]
== Deploy Configuration in Maven `settings.xml`

To upload artifacts to a bucket the user must authenticate with a
username and password. The username and password need to be retrieved
from the link:https://code.google.com/apis/console/?noredirect[API Console]:

* Go to the `Gerrit Code Review` project
* In the menu on the left select `Google Cloud Storage` >
`Interoperable Access`
* Use the `Access Key` as username
* Click under `Secret` on the `Show` button to find the password

To make the username and password known to Maven, they must be
configured in the `~/.m2/settings.xml` file.
