Compiling with twodifferent jdks?

["Schmolzi, Christian" <cs...@debis.com>]

Hi,

I am working on a buildfile for a project where there's a need to
compile one part with jdk 1.1.7B and the other part with jdk 1.2.2.
The package-structure is as follows:

a/b/c/compilethiswith117b/**/*.java and
a/b/c/compilethiswith122/**.java

Is there an easy way to do this under Unix and Windows?

Ciao,
Christian

I believe what you really want is to recompile different packages using   
different Java class libraries from Java 1 and Java 2 appropriately.

To achieve that easily with ANT, simply specify a compiler to be jikes,
and use two javac tasks, feeding them with different java runtime
libraries inside the classpath parameter: 
$JAVA1_HOME/lib/classes.zip (for the jdk1.1.7 case) and
$JAVA2_HOME/jre/lib/rt.jar  (for the jdk1.2.2 case).

Can you tell me why you cannot recompile
a/b/c/compilethiswith117b/**/*.java with jdk1.2.2 ?
