Answer 1

Put this in module(s)(or module's pom.xml) that you don't want to deploy:

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

Since this is inherited by submodules, you have to put this in submodules that you do want to deploy:

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

The skip property will be true in all submodules... so nothing at all will be deployed.... – Invaluable

@Invaluable just set the skip property to false for all the submodules you want to deploy... – Outstretch

Also if you have a situation where you need to deploy overlapping sets of module, use profiles. Example: module is [m1, m2, m3] user setting-foo deploy[m1, m2] and under 'setting-bar' deploy[m2, m3] ref: maven-profile – Pellucid

Answer 2

Another suggestion could be doing the following:

mvn deploy -pl SubModuleB

This is very simple and easy solution. – Afterthought

This way the parent pom is not published and causes the project who references the module to fail when building – Tecu

You would also get Could not resolve dependencies for project if SubModuleB is depending on any other module (eg. Submodlue C). – Springhead

Answer 3

This is working on my side Put the plugin declaration in the parent pom , skip=true, but set inherited=false. This prevents from repeating the <maven.deploy.skip> on each child modules.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.8.2</version>
    <configuration>
        <skip>true</skip>
    </configuration>
    <inherited>false</inherited>
</plugin>

This worked for me. Similar to other answer except added missing plugins element. Add to parent POM.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-deploy-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <skip>true</skip>
            </configuration>
        </plugin>
    </plugins>
</build>

You also need to re-enable the deploy for each sub-module that you want to deploy with a <skip>false</skip> – Unpeopled

Answer 5

You can use the technique described in my blog.

In this case, you'd disable default-deploy (or what the name is) in the root pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
    <executions>
        <execution>
            <id>default-deploy</id>
            <phase>none</phase>
        </execution>
    </executions>
</plugin>

And then enable it for submodules:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
    <executions>
        <execution>
            <id>default-deploy</id>
            <phase>deploy</phase>
        </execution>
    </executions>
</plugin>

Answer 6

You can configure the maven-deploy-plugin in the POM of a module to exclude it from the deploy:

<build>
  <plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-deploy-plugin</artifactId>
     <version>2.4</version>
     <configuration>
       <skip>true</skip>
     </configuration>
   </plugin>
   ...
</build>

Hi Raghu ...couldnt make it work ...tried putting the code into parent pm,but it gives the same result – Fecundity

Answer 7

First, build the whole project locally mvn clean install ,then cd to where the module is ProjectA -> Submodule B, and run deploy command:

I-am-in-Submodule-B-directory$ mvn -DskipTest deploy
