Using profiles to control which Maven modules are built

Question

I have the following XML in my maven POM.xml:

<profiles>   <profile>      <id>default</id>      <activation>         <activeByDefault>true</activeByDefault>         <property>            <name>default</name>            <value>!disabled</value>         </property>      </activation>      <modules>         <module>m1</module>         <module>m2</module>         <module>m3</module>      </modules>   </profile>   <profile>      <id>x</id>      <modules>         <module>m1</module>      </modules>   </profile> </profiles> 

What I'm trying to achieve is this:

1. When I run mvn install, I want it to build m1, m2 and m3 projects.

2. When I run mvn install -Px, I want it to only build m1.

My current problem is that with the code above, option 2 builds all m1, m2 and m3.

Found the solution guys, define 'x' profile first and the 'default' and it works fine (insane Maven!!). Here's the final result:

   <profiles>       <!-- DO NOT CHANGE THE *ORDER* IN WHICH THESE PROFILES ARE DEFINED! -->       <profile>          <id>x</id>          <modules>             <module>m1</module>          </modules>       </profile>       <profile>          <id>default</id>          <activation>             <activeByDefault>true</activeByDefault>          </activation>          <modules>             <module>m1</module>             <module>m2</module>             <module>m3</module>          </modules>       </profile>    </profiles>
