When we create a C-App project using Carbon Studio, we have to use Carbon Studio to create and export the Car file for that C-App project. Currently we don't support creating and exporting Car file outside of Carbon Studio. But we should be able to build and export Car file from outside of Eclipse. This is very useful if we have integrated source repositories with a continuous integration server such as Husdon CI server. Therefore we need to support Apache Ant building for C-App projects. This issue is to request that feature in a future release of Carbon Studio.
