Generation build.xml programatically [message #336726]

Hi

I want to build Eclipse projects in continous integration. For that, I
need to generated the build.xml programatically everytime.

I have read about the eclipse.buildScript target, but it seems is only for
plugins/features/fragments. I am having normal Java projects.

Is there any way to do it?

Thanks,
Aakash

Can you explain the need to generate a build.xml each time you start a
continuous integration cycle?

We first export the ant build file, by Right click on project -> Export ->
Ant build file. Then the ant "build" target is called from our continuous
integration script.

If something leads to a change in the .classpath file, like adding an
external jar, the build.xml becomes outdated and this leads to an error in
continuous integration.

Thanks

By "everytime" do you mean every time a file in the project is changed
(or a subset of files)? If so, then I would use an
IResourceChangeListener and in response to changes call whatever API is
necessary to do the build.xml export.
This should help get you started:
http://www.eclipse.org/articles/Article-Resource-deltas/reso urce-deltas.html

To discover the API you need to call for the export, open the buildfile
export wizard and then use the Plug-in Spy (Shift+Alt+F1) to learn what
class implements that wizard.

Hope this helps,
Eric
