 ### Build
-- [x] **targets**: **[Build Target]** - A list of targets to build
- - [x] **name**: **String** - the name of the target
- - [ ] **buildTypes**: **[String]** - A list of build types for this target. The default is all types. The build types are:
-		- `run`
-		- `test`
-		- `profile`
-		- `analyze`
-		- `archive`
+- [x] **targets**: **String** or **[String]** - A map of target names to build and which build types they should be enabled for. The buildTypes can either be `all`, `none` or an array of the following types:
+	- `run`
+	- `test`
+	- `profile`
+	- `analyze`
+	- `archive`
