[Maven's memory] How to avoid adding the MAVEN_OPTS variable?
Hello everybody,
Is there anyway to configure MAVEN_OPTS from the POM file (no variable)?
For example, I want to configure Maven's memory is 768m. But I don't
want to add the MAVEN_OPTS variable in the environment. This is possible
to configure my POM? If yes, please send to me how to do this.
Thanks in advance,
Kinh

Right, maven would have to fork a new vm for the project.

No. Nor could their be, at least for the case you're describing. Maven's JVM has already started by the time it parses the POM. For plugins which fork a new VM, you may be able to provide these options. For example: http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-with-memory-enhancements.html.

You can't and you shouldn't. The POM describes a Project, not the Java
environment for Maven.

And the surefire plugin support this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven-surefire-plugin.version}</version>
<configuration>
<forkMode>once</forkMode>
<argLine>-Xmx1024m -XX:MaxPermSize=128M</argLine>
</configuration>
</plugin>
But I don't think you can for maven itself. I too, at times, wished there
was a way because otherwise we have to set the maven opts to the worse case
for all our poms.

As you see using these command files (mavenrc , .mavenrc or
mavenrc_pre.bat) this is nothing to do with Maven plugins, the command
files are called mvn command files itself.
So every time you execute mnv command the set MAVEN_OPTS are effective.

Just so you guys know, if you use a Maven plugin to set MAVEN_OPTS, it
would only take effect if Maven spawns a child process. It will never
effect the main Maven execution.

Even better is use files to put these MAVEN_OPTS definitions
in Linux env : /etc/mavenrc or $HOME/.mavenrc file
in Windows %HOMEDRIVE%%HOMEPATH%\mavenrc_pre.bat file which is usually C:\Documents and Settings\<username>\mavenrc_pre.bat
With this way each Maven user can configure exact values what they want
for their environment.
