    copied!<p>I'm having an issue migrating my project to SBT <code>0.13</code>.</p> <p>For some reason, the snippet from <a href="http://www.scala-sbt.org/release/docs/Howto/generatefiles.html#sources" rel="nofollow noreferrer">Generate sources</a> from the SBT documentation doesn't work for me.</p> <p>Neither a simple <code>.sbt</code> build definition nor a Scala build definition work, unfortunately. Project definition is taken from the documentation:</p> <pre><code>name := "sbt-test" sourceGenerators in Compile += Def.task { val file = (sourceManaged in Compile).value / "demo" / "Test.scala" IO.write(file, """object Test extends App { println("Hi") }""") Seq(file) } </code></pre> <p>The compiler complains about the type error when compiling the project definition:</p> <pre><code>~/P/sbt-test ▶ sbt [info] Loading global plugins from /Users/phearnot/.sbt/0.13/plugins [info] Loading project definition from /Users/phearnot/Projects/sbt-test/project /Users/phearnot/Projects/sbt-test/build.sbt:3: error: No implicit for Append.Value[Seq[sbt.Task[Seq[java.io.File]]], sbt.std.FullInstance.M[Seq[java.io.File]]] found, so sbt.std.FullInstance.M[Seq[java.io.File]] cannot be appended to Seq[sbt.Task[Seq[java.io.File]]] sourceGenerators in Compile += Def.task { ^ [error] Type error in expression Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? </code></pre> <p><strong>UPDATE:</strong> Now that <a href="https://stackoverflow.com/users/1078381/alexiv">AlexIv</a> has pointed out the problem in my SBT file definition, I wonder what is the proper way to move it into a Scala build definition?</p>
