Answer 3

Right, I'm not sure if it will work for others but worked for me.

I changed proxyPort to 8080 and used jcenter instead of Maven. But I had to apply expeption to use HTTP instead of HTTPS. This is what I have in my build.gradle for build script and allprojects

buildscript {
  repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

allprojects {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

UPDATE: 06/08

I have recently updated Gradle and plugin version and had some problems. It was complaining about plugin com.android.application

I did some digging around and changed

 jcenter {
    url "http://jcenter.bintray.com/"
}

to

repositories {
    maven { url 'http://repo1.maven.org/maven2' }
}

6 years later here, but for them who are stil facing this issue, I solved it as following. It happened when my module had a different gradle version than the main project. I had gradle version 3.5.3 in project and an older version in module. So, I Just updated that version. The file is here:

./node-modules/[module-name]/android/build.gradle

In my case deleting the .gradle folder worked for me.
