Others may have their own good ideas approaches(or their own needs). So to make long story short, you want: 1. Be able to partially build project. This is already supported[1], so I do not understand what is missing. [1] http://www.ovirt.org/OVirt_Engine_Development_Environment#Usage 2. Setup all components with debug port enabled at development mode. This can be achieved quite easy, but there is a catch... in tools you might want to add environment variable to halt at startup and wait for debugger. Patches are welcomed! 3. Be able to run all under ide without installation. This is how developers worked until recently, it created an entire new category of art, running engine without actually setup it. Artists are hard to find and harder to duplicate. So I am sorry, but this is not the right way to go. You can build partially, install over existing setup, and debug using remote debugger. Any other mean is a waste of resources to set up, maintain and sync. Regards, Alon Bar-Lev. ___ Engine-devel mailing list Engine-devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/engine-devel

Re: [Engine-devel] Java Development Lifecycle
For me personally the most time consuming part of development is when I have to frequently change/update configurations of the engine, I have to manually deal with the interactive setup wizzard. Thanks to the new development environment I managed to automate all other parts of my process using scripts, except engine-setup. I would greatly appreciate if there were some way of supplying 'answers' to the engine-setup from command line (or answer files, like in the 'full' version) so it could be scripted.
