How to run a plugin only on a particular platform

Question

I have a maven plugin that only needs to execute on linux. I found this configuration that seems to work

How do I make this plugin run only on non-Windows platforms?

<profiles>
  <profile>
    <activation>
      <os>
        <family>!mac</family>
      </os>
    </activation>
    <build>
      <plugins>
        <plugin>
          ...
        </plugin>
      </plugins>
    </build>
    ...
  </profile>
</profiles>

How do I modify it so that it executes only on linux?

Answer 1

There is no OS <family> value that distinguishes Linux from Unixes, but you can use <name> instead.

<profiles>
  <profile>
    <activation>
      <os>
        <name>Linux</name>
      </os>
    </activation>
    <build>
      <plugins>
        <plugin>
          ...
        </plugin>
      </plugins>
    </build>
    ...
  </profile>
</profiles>

FYI, to double-check the value for <name> on your Linux machine, execute java -XshowSettings:properties and look for the os.name property. (On all Linux distributions I have checked, this is just Linux.)
