Java package not found when building Android

help
1

I’m upgrading to Meteor v2.10 and getting “package not found” errors (see below) when building Android on both Macs and Linux. I’ve added the cordova-plugin-androidx-adapter; put platform-tools, build-tools and latest/bin in the path; set ANDROID_SDK_ROOT accordingly; and even added the android-30 directory to CLASSPATH – but still the errors.

Any suggestions on what I’m missing? Many thanks.
