I’ve made a binary build of the engine for my team to use but on their computers I get the following errors when I try to package for Android:

Packaging works fine for me with the exact same build. Androidworks is installed on all machines. I’m using Visual studio 2019 and they’re still on 2017, maybe that’s why?

Figured out what was causing this. SVN ignores .a files by default and the plugin included .a libs in the thirdparty folder. Removing .a from the ignored file extensions list in SVN solved the issue.
