Run ANT with different JVM [message #48944]

Can anybody tell me if it is possible to run Ant in another JVM then the one
that I use to run Eclipse. I need to use Java 1.4 to run Eclipse since some
nice plugins requires that but our applications must be compiled with Java
1.3.

Please help me with this since it prevents us from using Eclipse.

In the latest integration builds this is possible. It will be available in
the milestone 1 build that will be coming out (hopefully) at the end of this
week.
See the JRE tab that is now available for any Ant launch configuration.

But to achieve what you desire you do not need to launch Ant in a separate
VM.
The javac task of Ant support specifying a target attribute.
Use something like
<javac target="1.3" ...>
</javac>
This will generate 1.3 VM compatible class files.

Hi,

Thank you for that information. I guess that I have to wait then. I have
allready tested the target property of ant but it doesn't work. The problem
is the following:

[javac] bad class file:
C:\Progra~1\Java-1.4.1_02\jre\lib\rt.jar(java/util/TimerTask .class)
[javac] class file has wrong version 48.0, should be 47.0
[javac] Please remove or make sure it appears in the correct
subdirectory of the classpath.
[javac] import java.util.TimerTask;

It works if I run it through the 1.3 compiler but not through the 1.4
compiler.
