Script using NuProcess fails in ammonite > 1.0.5

[mprihoda]

I have a simple Hello World example script with NuProcess that works in Ammonite 1.0.5, properly downloading the JNA dependency.

Since 1.1.0, JNA is not downloaded and script throws

java.lang.IllegalArgumentException: class com.sun.jna.JNIEnv is not a supported argument type (in method Java_java_lang_UNIXProcess_init in class com.zaxxer.nuprocess.internal.LibJava8)

  ammonite.$file.nuprocess$.<init>(nuprocess.sc:26)
  ammonite.$file.nuprocess$.<clinit>(nuprocess.sc)

Since 1.2.1 until current 1.6.6 JNA is not downloaded and script throws:

I'll try to find the time to fix it in the next few days, but any ideas that would speed up my progress are welcomed.

Using nuprocess 2.0.0 and ammonite 2.1.4 appear to work as expected.

amm --no-remote-logging nuprocess.sc
Hello World!
