Not sure what I'm doing wrong. My `~/.sbt/0.13` looks like:

```
addSbtPlugin("com.hanhuy.sbt" % "android-sdk-plugin" % "1.3.19")
addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.6.0")

```

Attempting to `sbt publishLocal` yields:

```

I have the latest (0.13) version of sbt and the latest (2.11.6) version of Scala installed. I'm new to sbt -- what's missing here?
