not handling javac 10 and 11

[ghost]

Issue description

cordova run android --emulator is not working on java installed via brew (both oracle and openjdk versions).

Reproduction

• On mac os 10.13.6:
• npm module cordova-android 7.0.0 (installed automatically by cordova platform add android)

oracle

• brew install oracle_java
• cordova run android --emulator
• fix the JAVA_HOME envvar
• getting UnhandledPromiseRejectionWarning: CordovaError: Requirements check failed for JDK 1.8 or greater

openjdk

• brew tap brew tap AdoptOpenJDK/openjdk
• brew install adoptopenjdk-openjdk11
• fix the JAVA_HOME envvar
• getting UnhandledPromiseRejectionWarning: CordovaError: Requirements check failed for JDK 1.8 or greater
• i know this is not brew cask, it's a third party brew tap, but as we speak the guys at adoptopenjdk are working on pull request to official brew cask for openjdk

Investigation

As far as I discovered file check_reqs.js is responsible, it has problem recognising java10 and java11 because javac -version outputs to stdout instead of stderr. Also the regex.

As far as I know, the Android tools require Java 8 and are not compatible with newer versions.

@odrzutowiec The Problem with check_reqs.js has already been fixed in #446 but the fix has not been released yet.

However, as @dpogue said: The Android tools require Java 8 (exactly). You can make it work with newer versions in some scenarios but it's generally not worth the trouble.

You can try to verify this using cordova@nightly and cordova-android@nightly. You then should get the message Requirements check failed for JDK 1.8.
