Android builds fail with Java 9 JDK and Unable to list target platforms error

Android

-

With the latest public versions of Unity (2017.1.1f1), Android Studio/SDK tools(26.0.2), and JDK (Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode), Android builds failed early on with:

Error:Invalid command android
CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct.
See the Console for more details. Error building Player: CommandInvokationFailure: Unable to list
target platforms. Please make sure the android sdk path is correct. See the Console for more details.

A similar problem (same error message, but different cause) has been reported about 6 months ago: https://issuetracker.unity3d.com/issues/android-build-fails-when-the-latest-android-sdk-tools-25-dot-3-1-version-is-used

In my case, downgrading to JDK 8 fixed the problem.

Reproduced with:
2017.3.0b4, 2017.2.0f3, 2017.1.2f1, 5.6.3p4, 5.5.5f1

    Unfortunately there are compatibility issues between JDK9 and JDK10 and Android SDK.
    The bugs have been reported to Google, we are working on a full-featured fix.
    As a workaround, for now please UNINSTALL JDK9/10 and INSTALL only JDK8 (64-bit).
    We apologize for the inconvenience caused.

    Feel free to check the status at the forums as well: https://forum.unity.com/threads/java-9-jdk-9-support-by-unity-android.499354/

    As of 9/12 Unity will tell you to download JDK 8 if you try to use 10. Thanks for this warning :)

    My solution was uninstalling Java 10 and reinstalling Java 8 on Windows 10.
