Description Eugene Kuleshov

Since Eclipse version 3.0 M4, JDK 1.4 became a requirement to run Eclipse.
Unfortunately there are number of projects that require 1.3 to compile. So, it
is possible to configure JRE to run Java apps and unit tests, but not to run
Ant. This is very critical issue for some projects, because Ant build just does
not work for JRE 1.4.

The existing possibilities:

you can configure your javac task to compile to a 1.3 compatible target (see 
the documentation for the Ant javac task about the "source" and "target" 
attributes)

you can specify an alternate JRE for an Ant build using the JRE tab for the 
Ant launch configuration (just like Java apps and unit tests).

Thank you for the hints. 

The only suggestion I have is to make such JVM settings not project specific,
but global. And then allow to overwite it on a project level. Usually entire
workspace has to be build on a similar manner.

Bug 38263 exists for setting the global vm setting.
