Hello,=20

There are some interseting arguments to exec like spawn (standard is =
false) etc.
I never tried this, so someone else might know exactly.

But I think it is worth a try to use the exec task for a test and see =
what happens.
I think it is possible to keep the settings of a Batchfile you run.

Greetings

Betreff: RE: setup environment for java task

Thanks for the suggestion, but here is my problem:

1. These batch files are used at runtime from an end user after =
installing the product with an installer.
2. Therefore, these batch files cannot be converted to ANT as that would =
duplicate the logic and could get out of sync 3. I am trying to recreate =
an end user's runtime environment with ANT so that I can launch our =
application or run unit tests with the same environment which is why I =
want to execute those same batch files 4. executing each batch file in =
an exec task only affects the process spawned by the exec task and is =
not remembered from one batch file to the next so when I finally launch =
my java class, that environment from the batch files is already gone, I =
think

 Hello,

I would translate the "bat" files to ANT-Tasks.
This is a lot of work, but than your Antfile can decide what bat-jobs =
you run and when.

Another way is to run the bat-files itself inside Ant using the =
exec-task, which is a bit tricky to handle.

To be honest: I dont like Batchfiles, so I would prefer "translating" =
the stuff to Ant, so that I have the control out of Ant.
But maybe, if you need the Batchfiles as well, then you produce =
redundancy, if you translate it to Ant.

Greetings

Juergen

Betreff: setup environment for java task

Let's say I have a series of setupEnv.bat files in my source repository =
that I need to execute as part of setting up my runtime environment =
before executing my java code with the java task.  I don't see an =
elegant way of doing this.  I could execute these bat files as part of =
my build.bat before invoking ant itself.  However, I don't like this =
approach as it would interfere with my build environment.  I only want =
it to affect my runtime environment when I launch java code from my =
build.xml.  For example, my "build.bat compile" command should not =
invoke the setupEnv.bat files, but my "build.bat launch" command should. =
 I don't want to start writing a lot of logic in my simple build.bat =
script which just launches ant to detect what target is being run to =
know whether to invoke the setupEnv.bat files.  I was hoping for =
something more elegant inside ANT itself.  The java task already =
provides a way to pass in environment variables, but I don't see how I =
could have it execute some bat files first to setup the environment.

Does anybody know of an elegant way of doing this or some 3rd party ant =
plugin that can do it?

I don't even know if it is possible in java.  You would have to somehow =
invoke a separate process and then feed it commands to run (like =
executing batch files) to setup its environment, and then pass it the =
JVM command line to finally invoke the java class.
