Look up hostname from Maven

问题:

I'm looking for a way to look up hostname and set it as a property in Maven.

This does not work in all environments:

...
<properties>
   <hostname>${env.HOSTNAME}</hostname>
</properties>
...

Any suggestions?

Use a groovy script to set the project property

    <plugin>
        <groupId>org.codehaus.groovy.maven</groupId>
        <artifactId>gmaven-plugin</artifactId>
        <executions>
            <execution>
                <phase>generate-resources</phase>
                <goals>
                    <goal>execute</goal>
              </goals>
               <configuration>
                  <source>
                  project.properties["hostname"] = InetAddress.getLocalHost().getHostName()
                 </source>
             </configuration>
         </execution>
      </executions>
 </plugin>

${env.COMPUTERNAME} works for me..

I ended up with a simple solution to the cross-plattform problem:

<manifestEntries>  
    <Build-Host-Linux>${env.HOSTNAME}</Build-Host-Linux>
    <Build-Host-Windows>${env.COMPUTERNAME}</Build-Host-Windows>
</manifestEntries>

The comment posted by user1885834 was working best for me: Create profiles for Windows and Linux and use the respective environment variables to define a new property ${hostname}, to be used anywhere.

<profile>
   <id>unix</id>
   <activation>
      <os>
         <family>unix</family>
      </os>
   </activation>
   <properties>
      <hostname>${env.HOSTNAME}</hostname>
   </properties>
</profile>
<profile>
   <id>windows</id>
   <activation>
      <os>
         <family>Windows</family>
      </os>
   </activation>
   <properties>
      <hostname>${env.COMPUTERNAME}</hostname>
   </properties>
</profile>
