Error in fail: maven_install.json contains an invalid input signature and must be regenerated. This typically happens when the maven_install artifacts have been changed but not repinned. PLEASE DO NOT MODIFY THIS FILE DIRECTLY! To generate a new maven_install.json and re-pin the artifacts, either run:
  | REPIN=1 bazel run @unpinned_maven//:pin
  | or:
  | 1) Set 'fail_if_repin_required' to 'False' in 'maven_install'
  | 2) Run 'bazel run @unpinned_maven//:pin'
  | 3) Reset 'fail_if_repin_required' to 'True' in 'maven_install'
