+#!/bin/sh
+#
+# This script runs the LicenseFinder gem to verify that all licenses are
+# compliant. However, bundler v2.2+ and LicenseFinder do not play well
+# together when:
+#
+# 1. There are native gems installed (e.g. nokogiri, grpc, and google-protobuf).
+# 2. `Gemfile.lock` doesn't list the platform-specific gems that were installed.
+#
+# A full explanation is here:
+# https://github.com/pivotal/LicenseFinder/issues/828#issuecomment-953359134
+#
+# To work around the issue, we configure bundler to install gems for the
+# current Ruby platform, which causes Gemfile and Gemfile.lock to be
+# updated with the platform-specific gems. This allows LicenseFinder to
+# run properly. After it finishes, we clean up the mess.
