Publish failing with 400 error but no debugging information

[samtstern]

Plugin Version: 1.8.4 and 1.8.5

I am trying to publish a new version of my library and all my builds fail like this:

* What went wrong:
Execution failed for task ':library:bintrayUpload'.
> Could not upload to 'https://api.bintray.com/content/firebase/geofire/geofire-android/3.1.0/com/firebase/geofire-android/3.1.0/geofire-android-3.1.0.aar': HTTP/1.1 400 Bad Request [message:Error occurred while uploading]

It's not the aar itself. If I remove that from the publication then the failure is the javadocJar, if I remove that then the sourcesJar and if I remove that then the pom.

Is there any way I can find out what is wrong with my request? There's nothing in --debug

Note that this repo was previously able to publish and even if I revert to the last published commit and run publish again (with a bumped version number) it fails with this error. This implies it's a backend change/bug or somehow an error with my account.

I can reproduce this with curl so it may not be related to the plugin.

The file I want to upload

$ ls -al common/build/outputs/aar/common-release.aar
-rw-r--r--  1 samstern  primarygroup    13K Nov 10 12:06 common/build/outputs/aar/common-release.aar

Uploading:

$ curl -i --user $BINTRAY_USER:$BINTRAY_KEY -X PUT -T common/build/outputs/aar/common-release.aar https://api.bintray.com/content/firebase/geofire/geofire-android-common/3.1.0/com/firebase/geofire-android-common/3.1.0/geofire-android-common-3.1.0.aar

Can't upload files through the UI either:
