In the Maven Settings shown in Example 13.3, “Configuring Deployment Credentials for Nexus Site Deployment”, you configured your Maven instance to use the default deployment user and password. To successfully deploy a site to Nexus, you will need to make sure that the deployment user has the appropriate role and permissions. To add the site deployment role to the deployment user, click on Users under the Security section of the Nexus menu, and then highlight the deployment user as shown in Figure 13.4, “Adding the Site Deployment Role to the Deployment User”.

Locate the "Repo: All Maven Site Repositories (Full Control)" role in the Available Roles list, click this role, and drag it over to the Selected Roles list. Once the role is in the Selected Roles list, click on the Save button to update the roles for the deployment user. The deployment user will now have the ability to publish sites to a Maven Site repository.
