What if, instead of using the custom string variable jde-ant-program, a new
custom variable jde-ant-invocation-style is a choice between invoking a
specific script or invoking a function that generates the appropriate Ant
command. Perhaps something like:
Jde Ant Invocation Style: [Hide]
(*) Use program or script
Script/Program : __________________________________________
( ) Invoke function
Function : ________________________________________________
This way, jde-ant is flexible enough to do the things you want. When
jde-ant-build is called, the invocation style variable will be checked, and
the ant command will be built accordingly...
A standard function could be created to invoke the jvm defined by
'jde-run-java-vm' using the classpath defined by
'jde-global-classpath'/'jde-run-option-classpath' and the Ant main class.
Thoughts?

Hello,
I understand your position about running ant. Would it be possible
to allow changes so that you can use it either way? They way you have
outlined below, via the ant batch/shell script, and invoking a JVM to
run ant.
Allowing jde-ant to be invoked via a JVM directly allows more
flexible within Emacs. Using this model allows changes to be
controlled within Emacs and not in the batch/shell script. Therefore,
change need to occur within the environment of the project and not to
the batch/shell script.
I have made the necessary changes to jde-ant.el to invoke the JVM.
It was not hard, and very little changes required.
I was thinking have a boolean switch (jde-ant-use-jvm) that is
checked to see how to invoke ant. This allows users to invoke it the
way you intended or to allow customization totally in Emacs.
I believe this is a natural evolution in jde-ant. I have no
hesitation to provide my services to make the changes and help maintain
those changes.
What do you think? Is it viable?
