Gradle: android javadoc generation failed

Troubleshooting General Help
1

When I try to build JMonkeyEngine using gradle 8.9, I get an exception.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':jme3-android:javadoc'.
> Javadoc generation failed. Generated Javadoc options file (useful for troubleshooting): '/home/codex/java/prj/jmonkeyengine/jme3-android/build/tmp/javadoc/javadoc.options'

The generated javadoc.options:

It seems to be only jme3-android that has this problem. The javadoc for the other libraries (i.e. jme3-core) seemed to generate just fine. I’ve also been having trouble with getting gradle to tunnel through my network proxy, so this may be related to that, idk.

What was the exception?

Seems like the proper software is missing for some reason.
Edit: or maybe the target directory wasn’t created? Hard to say from that message.

After trying a few things, I think this was caused from using a gradle seperate from the sdk. When I used the gradle with the sdk, it got past that part.

Gradle outside the SDK should work, though.

…lots of people never use the SDK.
