How to skip install phase in Maven build if I already have this version installed in repo

You can bypass like this

-Dmaven.install.skip=true

---

<profiles>
   <profile>
     <id>skipInstall</id>
     <activation>
       <property>
         <name>maven.install.skip</name>
         <value>true</value>
       </property>
     </activation>
     <build>
       <pluginManagement>
         <plugins>
           <plugin>
             <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-install-plugin</artifactId>
             <executions>
               <execution>
                 <id>default-install</id>
                 <phase>none</phase>
               </execution>
             </executions>
           </plugin>
         </plugins>
       </pluginManagement>
     </build>
   </profile>

Last week Olivier Lamy patched this jira.

Most maven plugins can be skipped by specifying something like:

        <plugin>
          <artifactId>maven-install-plugin</artifactId>
          <version>X.Y</version>
          <configuration>
            <skip>true</skip>
          </configuration>
        </plugin>

you can also set up build profiles to set properties and use that to determine the value. for example, running the command: mvn -Pexample would select the "example" profile. The POM would then contain:

...
  <properties>
    <skip.install>false</skip.install>
...
  </properties>

...
    <profile>
      <id>example</id>
      <properties>
        <skip.install>false</skip.install>
      </properties>
    </profile>
...
    <plugin>
      <artifactId>maven-install-plugin</artifactId>
      <version>X.Y</version>
      <configuration>
        <skip>${skip.install}</skip>
      </configuration>
    </plugin>
...

Using these POM additions, the default behavior for the install plugin will be to perform its default goal, but if the example profile is selected, then the install plugin will skip its goal.

Using what I learned from the other answers, this was the cleanest result for me.

In my super pom I added a pluginManagement/plugin to disable default-install and default-test phases when the property deployOnly is set.

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <version>2.5.2</version>
                <executions>
                    <execution>
                        <id>default-install</id>
                        <configuration>
                            <skip>${deployOnly}</skip>
                        </configuration>
                    </execution>
                    <execution>
                        <id>default-test</id>
                        <configuration>
                            <skip>${deployOnly}</skip>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

So on the command line, I can disable install and test phases by adding -DdeployOnly.

mvn clean install       #build and test everything
mvn deploy -DdeployOnly #just deploy it
