The build launched by this button always do a
publish-local, it cannot be changed by configuration.
As a workaround, you could change your ivysettings.xml file to publish to another local repository.
Or you can also override the
ivy-publication:publish-local target (the target which does the publication) in a file
override.module.ant located at the root of your project:
By emptying the target, nothing is done by the target, so no publication.
But that requires to adapt your project sources files.
Starting from the SDK 5.4.0 it is now possible to launch the build in command line and decide which target to use, so you can execute:
to launch the build without publication, and
mmm publish local
if you want to build with publication.
Hope this helps,
