Mikael:
Yes that's correct. I wasn't sure and ran "javac -version " which
worked. But then realized my JAVA_HOME is using JDK 1.5.
Regardless, calling out in this fashion is probably not a good solution...
Now that I think about it, one can use ${java.version} as java.version
is a System property.
<project name = "test">
<echo message = "java version = ${java.version}"/>
</project>
Yielded:
Buildfile: build.xml
[echo] java version = 1.5.0
