Maybe the check_* function should output this information when it checks the actual values?

I liked the first commit (02296b9) better.

I do think it is good to add the statement that the user should check JAVA_HOME, PATH, and ANDROID_HOME settings.

As I said in the comments I am not so happy about not logging the actual environment variable values for the ANDROID_HOME setting. This is information that could really help someone figure out what is not working.

I think some things have been a little mixed up in check_reqs.js. There is module.exports.run that runs a combination of check_java and check_android, which seem to be designed to run independently and are also part of a longer list in module.exports.check_all. I think it would be good to clean this up a bit, but not before the coming Cordova 9 release discussed in apache/cordova#10.

Another thing we need to fix is that we should check ANDROID_SDK_ROOT, as discussed in #617. I think it would be ideal to get that in before Cordova, if possible.

In short, I would really favor keeping the updates simple and keep the existing log statements until we get a chance to make the updates to check ANDROID_SDK_ROOT and cleanup check_reqs.js.

I am now convinced that we should not log JAVA_HOME at this point. The follow other things still need to be fixed as I said before:

• need to keep log of ANDROID_HOME path
• error message for JDK 8 check failure needs to be fixed (fix indentation to pass eslint and split into multiple lines)
