Install nativescript on OSX 10.11 and run tns doctor without java installed and then follow the More Info link when the download java prompt appears. Can you not have the prompt prompt for the JDK instead?

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

No.

Hey @vchimev @dtopuzov can you verify this?

[dtopuzov]

With 2.1.0 RC if JAVA_HOME points to wrong location error is:

  ◠ Verifying CocoaPods. This may take some time, please be patient..
Error executing command 'javac'. Make sure you have installed The Java Development Kit (JDK) and set JAVA_HOME environment variable.
You will not be able to build your projects for Android.
To be able to build for Android, verify that you have installed The Java Development Kit (JDK) and configured it according to system requirements as
 described in https://github.com/NativeScript/nativescript-cli#system-requirements.

Can't see where we point to JRE.

Please reopen if you still have problems with {N} 2.1.0 (it will be available by the end of the month)

Ah, it may be something on the OS level then. The prompt I am referring too is a prompt given by OSX outside the terminal window. Not sure if there is a way to suppress that completely, but it would probably avoid the confusion. I followed the UI prompt that occurs outside of the terminal window vs what the text said in the terminal.

I confirm that tns doctor throws an error if no JDK/JAVA_HOME available:

My guess is that we execute a java command in the doctor service which results in the prompt below.

The "More info" button leads to http://www.java.com/en/download/mac_download.jsp which provides a download of JRE, but not JDK required by NativeScript.

I logged a separate issue here: #1922
