NullPointerExceptionでた

gistfile1.txt

jp.sf.amateras.scala.sbt_0.0.3.201112241216.jar

でプロジェクトを新規作成して、Update Dependency を実行したらNullPointerExceptionが発生した。

libraryDependencies ++= Seq(
  "junit" % "junit" % "4.8.1" % "test"
)

などと追記してもDependencyが追加されていない模様。

ソース上では次のようになっている。targetDirがnullなのかしら？
File targetDir = new File(getProjectsDirectory(), projectDir.getName());

IOUtil.removeDirectory(targetDir);
