Change output directory of sbt

Question

I want to change my output directory for some generated files, in this case generated objects from an XSD-Schema. Here is part of my Build file. ``` val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA, settings = Defaults.defaultSettings ++ buildInfoSettings ++ scalaxbSettings ).settings( sourceGenerators in Compile <+= buildInfo, buildInfoKeys := Seq[BuildInfoKey](name, version, scalaVersion, sbtVersion), buildInfoPackage := "hello", packageName in scalaxb in Compile := "models", sourceGenerators in Compile <+= scalaxb in Compile ) ``` This code puts my generated files into the below directory: ``` target/scala-2.10/src_managed/main/models/ ``` How can I change my buildfile to output the files to below instead? ``` /app/models/ ```

Accepted Answer

Check out the `sourceManaged` setting key. Any source generator tasks will generally put stuff in the file specified by that setting.

```
source-managed                 - target/scala-2.10/src_managed
compile:source-managed         - target/scala-2.10/src_managed/main
test:source-managed            - target/scala-2.10/src_managed/test
```

Note that the "compile" and "test" values base themselves off of the base "source-managed" value, which is in turn based on the value of `cross-target`, which is based on the value of `target` and a few others.

You can easily change the value of the `compile:source-managed` setting in an sbt build definition with the setting

```
sourceManaged in Compile := file("app/models")
```

If you want to base your setting off of another setting, like the project's base directory, you could use something more like

```
sourceManaged in Compile <<= baseDirectory { _ / "app/models" }
```

Of course, you can find plenty of info on using settings here: http://www.scala-sbt.org/release/docs/Getting-Started/More-About-Settings edit: Looks like that link is dead. It's been a few years so I'm not 100% sure, but this is probably close to what the original link talked about: SBT 0.13 - Build definition or SBT 1.0 - Build definition
