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/

    Experiencing same problem after computer rebuild: downloaded latest Android Studio and latest Unity and latest Java JDK. . Temporary fix was revert to Java JDK 8u161 and revert tools using link at tools_r25.5_windows.zip

    Same problem, same error message, it's not possible to create a build. I have only managed to solve this by downgrading JDK to 8u151 and also the android SDK (r25.2.5 - replacing "tools" folder). I would be really grateful if the developers could fix this, it's been a pain in the ass for a long time.

    Cbarnes_Bnea, Thank you so much for pointing this. Had already set the path to JDK8, but never thought that just having JDK9 will cause the error! Deleting JDK9 from the JavaVirtualMachines folder solves it!
