当我编译我的程序时，它编译得很好，但是，当我运行 scaladoc 时它不起作用。这是sbt compile编译良好sbt doc但不起作用的最小代码：

/**
* Doc here.
*/
object SigmaDDFactoryImpl {
lazy val ipfFactory = new SigmaDDIPFFactoryImpl {
  val inductiveIPFFactory = new SigmaDDInductiveIPFFactoryImpl {
    val sigmaDDFactory: SigmaDDFactoryImpl.this.type = SigmaDDFactoryImpl.this
  }
}
class SigmaDD
}

/**
* Doc here.
*/
abstract class SigmaDDIPFFactoryImpl {
type InductiveIPFType = inductiveIPFFactory.InductiveTypeImpl

val inductiveIPFFactory:SigmaDDInductiveIPFFactoryImpl
}

class SigmaDDInductiveIPFFactoryImpl {
class InductiveTypeImpl
object MyObj extends InductiveTypeImpl
}

/**
* Doc here.
*/

class OtherClass {
 type InductiveIPF = SigmaDDFactoryImpl.ipfFactory.InductiveIPFType

def method(inductiveElt:InductiveIPF) = inductiveElt match {
  case a:SigmaDDFactoryImpl.ipfFactory.inductiveIPFFactory.InductiveTypeImpl => None
  case SigmaDDFactoryImpl.ipfFactory.inductiveIPFFactory.MyObj => None
}
}

这是输出sbt doc：

我正在使用 sbt 0.13 和 scala 2.10.2。如何使这段代码工作？

我找到的解决方案是：

/**
* Doc here.
*/
object SigmaDDFactoryImpl {
lazy val ipfFactory = new SigmaDDIPFFactoryImpl {
  val inductiveIPFFactory = new SigmaDDInductiveIPFFactoryImpl // I removed the braces here
}
class SigmaDD
}

/**
* Doc here.
*/
abstract class SigmaDDIPFFactoryImpl {
type InductiveIPFType = inductiveIPFFactory.InductiveTypeImpl

val inductiveIPFFactory:SigmaDDInductiveIPFFactoryImpl
}

class SigmaDDInductiveIPFFactoryImpl {
class InductiveTypeImpl
object MyObj extends InductiveTypeImpl
}

/**
* Doc here.
*/

class OtherClass {
 type InductiveIPF = SigmaDDFactoryImpl.ipfFactory.InductiveIPFType

def method(inductiveElt:InductiveIPF) = inductiveElt match {
  case a:SigmaDDFactoryImpl.ipfFactory.inductiveIPFFactory.InductiveTypeImpl => None
  case SigmaDDFactoryImpl.ipfFactory.inductiveIPFFactory.MyObj => None
}
}

但是，我仍然想知道为什么scaladoc需要编译代码。
