[yunikkk]

Summary of changes

• fails on PRs to release branch picking incorrect android-v10.6.0 release - the build

$1:
$2:./plugin-compass/build/outputs/aar/plugin-compass-release.aar
$3:compass
$4:android-v10.6.0
Path to previous version of aar is not set, using 10.6.0
aar path is: s3://mapbox-api-downloads-production/v2/mobile-maps-android-compass/releases/android/10.6.0/maven/maps-compass-10.6.0.aar, checking file

• succeedes without any actual comparison on PRs to the main branch - the build

$1:
$2:./plugin-viewport/build/outputs/aar/plugin-viewport-release.aar
$3:viewport
$4:v10.8.0
Path to previous version of aar is not set, using 
aar path is: s3://mapbox-api-downloads-production/v2/mobile-maps-android-viewport/releases/android//maven/maps-viewport-.aar, checking file
s3://mapbox-api-downloads-production/v2/mobile-maps-android-viewport/releases/android//maven/maps-viewport-.aar doesn't exist on s3, skipping the check

After the change script correctly compares the previous release, e.g. build with 10.9.0-rc.1

$3:viewport
$4:v10.9.0-rc.1
Path to previous version of aar is not set, using 10.9.0-rc.1
