You can now deploy your Scala packages directly from SBT to your packagecloud repositories (including
Also, we’ve released support for deployment JARs, also known as “fatjars” or “uberjars” to the packagecloud CLI!
Read on to find out how to take advantage of these new features.
Deploying Scala packages from SBT
Thanks to the sbt-aether-deploy plugin, we can tell SBT to use our already existing maven/aether compatible wagon, maven-packagecloud-wagon, to deploy scala packages (even
SNAPSHOT versions) directly from SBT.
To resolve uploaded
SNAPSHOT versions, we use the built-in
sbt-maven-resolver-plugin (as of SBT 0.13.8)
The customized setup instructions for deploying Scala packages can be found in the “SBT Deploy” tab of the “Integrations / CI” section of your repository and in our general documentation: SBT Deploy documentation.
Similarly, the customized install instructions are located under the “Install” section of your repository, under the “SBT” tab.
Deploying “fatjars” to packagecloud.io
For JAR uploads that happen outside of a build tool environment, like for example our Web UI, CLI tool, or API endpoint, we use a set of heuristics to automatically detect the right maven coordinates (the
artifactId of a package) for that upload.
However, sometimes there isn’t enough metadata in the JAR package itself to reliably deduce the right coordinates. For these cases, you can supply the coordinates on the CLI by using
--coordinates= with the latest CLI update: package_cloud (0.2.36)
The coordinates take the format of
groupId:artifactId:version, for example:
package_cloud push username/reponame/java /path/to/package.jar --coordinates=com.mygroup:packagename:1.0.2
Alternatively, you can instruct your JAR packaging plugin to include the following entries in your JAR’s
MANIFEST.MF to avoid having to pass coordinates at all:
Being able to quickly and easily iterate on libraries privately within your organization, regardless if one team is using Scala and the other is using Clojure, can really help move your business forward. Feel free to pop into our Slack Room with any questions or issues you might have.
