"NoSuchElementException: None.get" when there is no main method #301

Closed mkotsbak closed 8 years ago

mkotsbak commented 8 years ago

In previous versions of Scala Native, I successfully created a wrapper library without a main method, but now it fails with:

java.util.NoSuchElementException: None.get
        at scala.None$.get(Option.scala:313)
        at scala.None$.get(Option.scala:311)
        at scala.scalanative.sbtplugin.ScalaNativePluginInternal$$anonfun$projectSettings$10.apply(ScalaNativePluginInternal.scala:112)
        at scala.scalanative.sbtplugin.ScalaNativePluginInternal$$anonfun$projectSettings$10.apply(ScalaNativePluginInternal.scala:111)

.get should not be used here, but instead handle this case with an error message. But it should also be supported to be able to create libraries?

Actually I'm still able to run "sbt package", but there should be an error message for "run".

Regarding the last question, I see there is a "nativeSharedLibrary" option, but I don't think I want to create a shared library for just a thin wrapper for another shared library?

This seems to be solved in commit 88fdd446e54a297d48752c2ea99097bcff0fe886.
