FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithDexMergerForDebug'.

So I have tried removing and adding again the platforms including the NPM packages and dependencies, I might miss something here.

These are my plugin list:

cordova-plugin-compat 1.0.0 "Compat"
cordova-plugin-device 1.1.4 "Device"
cordova-plugin-inappbrowser 2.0.1 "InAppBrowser"
cordova-plugin-ionic-webview 1.1.11 "Ionic's WKWebView Engine"
cordova-plugin-qrscanner 2.5.0 "QRScanner"
cordova-plugin-splashscreen 4.0.3 "Splashscreen"
cordova-plugin-whitelist 1.3.1 "Whitelist"
ionic-plugin-keyboard 2.2.1 "Keyboard"

And I am using the Cordova 8.0.0 and Ionic 3.19.1.

Tried following these link but still not working, anyone encountered this issue?

Tried adding this in platforms/android/build.gradle:

android {
    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 26
        multiDexEnabled true
    }
}

and encountered this error:

FAILURE: Build failed with an exception.

* Where:
Build file 'G:\projects\htdocs\staircraft-dev\staircraft\platforms\android\build.gradle' line: 56

* What went wrong:
A problem occurred evaluating root project 'android'.

Could not find method android() for arguments [build_1wqgehkb4d0me3f5qwdaxlppc$_run_closure3@628d8ac0, build_1wqgehkb4d0me3f5qwdaxlppc$_run_closure4@36355950] on root project 'android' of type org.gradle.api.Project.

Any help is appreciated.
