Exception during build-bundle when parts of the output path doesn't exist

Describe the bug When running build-bundle it seems that bundletool fails with an exception when a folder along the output path doesn’t exist yet. My build crashed on CI but was working fine locally, and the only difference I found was that the last step on the output path (android, as seen in the stacktrace below) didn’t exist on CI yet. Once I changed my pipeline to create that folder bundletool worked just fine.

Bundletool version(s) affected Version: 1.2.0

To Reproduce Call bundletool build-bundle --output="/some/output/path/bundle.aab" with a path where the last subfolder doesn’t exist yet.

Expected behavior Bundletool should create the output folder when it doesn’t exist, similarly to how it’s done at BuildApksCommand.java#L650.

Known workaround The workaround is making sure that the folder exists prior to calling bundletool 😉

Environment: OS: OSX 10.15.7

Additional context I’m using bundletool in Unity with the Google PAD plug-in, but I don’t think this makes a difference at all.

Thank you for the contribution!

It appears that this bug is the cause of https://github.com/google/play-unity-plugins/issues/74. I’ll update to 1.4.0 to see if it fixes the issue.
