Java SE 1.4 is the minimum to run Maven2 itself. However, it should be able
to fork off and execute any JDK. I don't know why M2 should always use a
source argument - if none was specified, shouldn't it not include that
argument (i.e. leave it as the default)?

Anyway, I have compiled for 1.3, but I didn't use a separate JDK. I set
source and target to 1.3, and used bootclasspath to point to rt.jar from the
1.3 JDK. The settings in pom.xml looked like this:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.3</source>
    <target>1.3</target>
    <compilerArguments>
      <bootclasspath>..\..\tools\jdk\1.3.1_15\jre\lib\rt.jar</bootclasspath>
    </compilerArguments>
  </configuration>
</plugin>

I don't know if this will fill Tung's needs, however. I've never used JDK
1.2 - it's ancient history. ;)
