Select JDK compiler
Hi!
I have projects to be compiled with Java 1.4, or Java 1.5 and how can
I explicitly select the compiler in build.xml?
When I set fork="yes" when calling <javac>, how do I know which JDK
compiler the <javac> is executing?
There are Java 1.4 and 1.5 installed in my environment, with JAVA_HOME
pointing to Java 1.5.

Hello!
You can always use JDK 1.5.
If you will need to compile project with java 1.4
you can specify <javac source="1.4" target="1.4" ...>
Of course, you can use properties here to avoid manual editing of build.xml:
<javac source="${ant.build.javac.source}" target="${ant.build.javac.target}" ...>
Built-in props "ant.build.javac.source" and "ant.build.javac.source" hold default value for JDK
that is running Ant.
When you need to compile with java 1.4 - just override these properties with
your own values.
Refer documentation of <javac> task for details.

hi Hezjing,
Try the executable attribute in <javac>.
By default it will be 1.5 for you.
however try setting this executable attribute to the filepath for 1.4
javac.exe, whereever you require the sources to be compiled with 1.4
JDK
hope this helps
regards
