How do I make a Maven module not export a jar?

I have a Maven build with three modules.

• Module A exports a jar.
• Module B depends on A and exports a jar.
• Module C is a set of regression tests that depend on A and B.

The reason the regression tests aren't just part of开发者_JS百科 module B is that they should be able to run against multiple versions of A and B to ensure backwards compatibility. I want to be able to run deploy from the top level build to create A.jar and B.jar, but not C.jar. Is this possible?

<properties>
     <maven.deploy.skip>true</maven.deploy.skip>
</properties>

If you don't need to create a JAR at all, you might want to add two more properties:

<jar.skipIfEmpty>true</jar.skipIfEmpty>
<maven.install.skip>true</maven.install.skip>

Note that you still need maven.deploy.skip, otherwise the build will fail during deployment.

---

The maven deploy plugin includes a skip options that prevents artifact deployment.

<plugin>
  <artifactId>maven-deploy-plugin</artifactId>
  <configuration>
      <skip>true</skip>
  </configuration>
</plugin>

You can try adding that to project C.

Use below for module C:

<packaging>pom</packaging>

---

Use a packaging of type pom for C and rebind all required plugins:

<project>
  ...
  <packaging>pom</packaging>
