In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML 107 location under system/bt/out/Default 108 1094. Right click on the project. Go to Preferences->C/C++ Build->Builder Settings. 110 Uncheck "Use default build command", but instead using "ninja -C out/Default" 111 1125. Goto Behaviour tab, change clean command to "-t clean" 113 114
