仅从 Maven WAR 项目部署类 JAR

Question

I have a Maven project which creates a WAR file as well as a JAR file (with the -classes classifier, using <attachClasses>true</attachClasses> in the maven-war-plugin config). When I run mvn deploy , both of these artifacts gets deployed to Maven Central (via Sonatype Nexus).

That's all very well, but it's not really necessary to deploy the WAR to Maven Central - just deploying the -classes JAR would be sufficient, since the WAR is always uploaded to our github site for download, and only the JAR will ever be used as a dependency to another project.

Is there a way to configure this in Maven? I thought that <primaryArtifact>false</primaryArtifact> in the maven-war-plugin config might fix it, but it did not.

According to the Maven WAR Plugin FAQs , this problem needs a bit of refactoring in order to be solved. You would have to split the project into one "classes" module that only produces the classes JAR, and a second module which builds the whole webapp into a WAR file. The WAR module can then include the JAR module as a dependency.

Different Maven profiles (one for building and deploying the JAR, another one to build the WAR and skip deployment) might be a solution too. But to be honest, that seems rather hacky and harder to maintain. I am not sure that it would make your life easier in the long run.
