Broken dependency: com.evilco.mc:nbt:1.0.2

[jcobol]

I am seeing a missing dependency when trying to build or run checks:

~/github/MPL$ ./gradlew check

> Configure project :
[warning] sonatype username or password not set

FAILURE: Build failed with an exception.

* Where:
Build file '/home/jhopkins/github/MPL/compiler/compiler.gradle' line: 136

* What went wrong:
A problem occurred evaluating project ':compiler'.
> Could not resolve all files for configuration ':compiler:runtime'.
   > Could not find com.evilco.mc:nbt:1.0.2.
     Searched in the following locations:

     Required by:
         project :compiler

A Github project which provides the dependency:

https://github.com/dotStart/NBT-Lib

Tried modifying build.gradle to use JitPack to build nbt-1.0.2.jar as part of the build but haven't succeeded yet.

Is this broken dependency a known issue or have I missed a setup step?
