Hello! Thank you for opening an issue with us!

As this appears to be an issue with Ionic App Scripts and not with the Ionic Framework, I will move this issue to https://github.com/ionic-team/ionic-app-scripts. Please follow the issue over and provide any further feedback or information over there.

Thank you for using Ionic

I got the new macbook and installed sdk-9 as instructed and stuck with this same issue.

[danielsogl]

The Android SDK don't support Java 9. downgrade to 8

[danbucholtz]

This doesn't seem to be an app-scripts issue.

Thanks @danielsogl.

Thanks,
Dan

@danielsogl Perhaps it would be good to remove the instruction from the docs about using it then?

http://ionicframework.com/docs/v1/guide/installation.html

Install the most recent Java JDK (NOT just the JRE).

I am using Android Studio 3 for a while now, and i dont remember installing jdk 8.. The Android SDK still don't support Java 9?

Hi All,

I had the same issue, while running cordova build.

java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

I have uninstalled Java JDK 9 and installed JDK 1.8, fixed the problem.

[mindaccentin]

I fixed the issue by uninstalled Java JDK 9 and installed JDK 1.8.
After this I got gradle issue in mac. Fixed that gradle issue as per the instruction in following
https://kodejava.org/how-do-i-install-gradle-in-os-x/

[climbican]

What, you have to go all the way back from 9 to 1.8 for it to work??? Does anyone else consider this a bit ridiculous?

[audacitus]

@climbican I think the numbering is a bit strange:
searches for JDK 1.8 point to JDK 8 (and so on)

Installed JDK 10 and had this error. currently downgrading. will update when done.

I'm on a Mojave MAC...

I'm having the same error, but my JDK version is the newest one (Version 11.0.1).

I will see if I install version 8 and test if the problem is solved.

[crashforce]

Actually, after deleting the newer version of JDK and installing version 8 the problem has been solved. We are waiting for the new version .. Meanwhile we are using this same one that has no error.
