Using Java 1.4 with Ant

[Pito Salas <pi...@eroom.com>]

I am having trouble convincing Ant to use Java 1.4 as the compiler for javac
tasks. If I set build.compiler to modern or javac1.4 it still always picks
Javac 1.3. Note that I have both 1.3 and 1.4 on my path. Does it simply pick
the first one it sees?

Also note that I'm running under Jbuilder 7, which runs under 1.3. Would the
"modern" setting look for 1.4 if it was able to locate both a 1.3 and a 1.4?

Do you have a system variable named JAVA_HOME set?  Where does it point 
to?  Do you have JAVA_HOME/bin in your system PATH?

The first one from your CLASSPATH, yes - unless you set fork to true,
in which case you can use the executable attribute to point to the
javac of JDK 1.4.

There is no way (for Ant) to tell the 1.4 javac from the 1.3 one.  It
simply loads and runs com.sun.tools.javac.Main.
