You can also upload a staged deployment via the Nexus interface. To upload a staged deployment, select Staging Upload from the Nexus menu. Clicking Staging Upload will show the panel shown in Figure 9.12, “Uploading a Staged Deployment in Nexus”.
To upload an artifact, click on Select Artifact(s) for Upload… and select one or more artifacts from the filesystem to upload. Once you have selected an artifact, you can modify the classifier and the extension before clicking on the Add Artifact button. Once you have clicked on the Add Artifact button, you can then configure the source of the Group, Artifact, Version (GAV) parameters.
If the artifact you are uploading is a JAR file that was created by Maven it will already have POM information embedded in it, but if you are uploading a JAR from a vendor you will likely need to set the Group Identifier, Artifact Identifier, and Version manually. To do this, select GAV Parameters from the GAV Definition dropdown at the top of this form. Selecting GAV Parameters will expose a set of form fields which will let you set the Group, Artifact, Version, and Packaging of the artifacts being uploaded. If you would prefer to set the Group, Artifact, and Version from a POM file which was associated with the uploaded artifact, select From POM in the GAV Definition dropdown. Selecting From POM in this dropdown will expose a button labeled "Select POM to Upload". Once a POM file has been selected for upload, the name of the POM file will be displayed in the form field below this button.
The Staging Upload panel supports multiple artifacts with the same Group, Artifact, and Version identifiers. For example, if you need to upload multiple artifacts with different classifiers, you may do so by clicking on Select Artifact(s) for Upload and Add Artifact multiple times. This interface also accepts an Artifact Bundle which is a JAR that contains more than one artifact.
Once a staging artifact upload has been completely configured, click on Upload Artifact(s) button to begin the upload process. Nexus will upload the artifacts to the Staging URL which will trigger any staging profiles that are activated by the upload. If a staging profile is activated, a new staging repository will be created and can be managed using the procedures outlined in Section 9.20, “Managing Staging Repositories in Nexus”.
