It looks you have Java 1.7.
{N} now require Java 1.8, see https://github.com/NativeScript/nativescript-cli#system-requirements

Ah, TNS doctor does not report any issues!

Doc should report this if possible +1

Please note I upgraded to v1.8 - And this actually does fix the primary issue. Yeah!

HOWEVER,

1. On 1.7, TNS Doctor as reported above said everything was good.
   2 On 1.8, TNS doctor now says I have issues with my ANDROID_HOME & android.bat file, even though I can run android.bat fine and I can now build perfectly fine.

I don't have those issues on my Win10 PC @NathanaelA w/ 1.8, I get:

Your components are up-to-date. No issues were detected.

No major issues now that I have Java 1.8 and running NS 2.0 on new apps. One minor issue about AppBuilderCallback (WTF - but it happened with 1.7.1 and has come up on Slack in recent weeks), and a good ole platform remove/add fix it every time.

+1 :) having the same issue.. tns doctor should report this

[dtopuzov]

Still valid in {N} 2.0.1. We do not check version, just check java is available.
However Java 1.7 looks already deprecated, see https://java.com/en/download/faq/java_7.xml

Fixed in #1824
