Android does not support Java 9/10. This has nothing to do with Ionic or Cordova but with the Android SDK.

Downgraded the Java version to 1.8, and I can able to build the APK now.

Thanks for the quick response @danielsogl ...!

Hi,

I have the same problem. I have dowgraded to java 8 but still same same error.

JAVA_HOME = /usr/lib/jvm/jdk1.8.0_181

@danielsogl, But how Android Studio compiles with my Java 10 if android does not support it? Do they include whole JDK ?

[rmacuna]

Having the same problem, Require 1.8. But android studio compiles correctly

Go to
/platforms/android/cordova/lib/check_reqs.js
and comment the line 370:

//throw new CordovaError('Requirements check failed for JDK 1.8 or greater');
This should do the trick ;)

@leovolpatto Your trick worked for me even with JDK 10.0.1
