project.http-client.version defined twice?!

[elharo]

If I'm reading this right, in the root pom project.http-client.version seems to be set to both 1.27.1 and 1.28.1. Perhaps an autoupdate gone wrong?

  <properties>
    <!--
      NOTE: if you make a change to these versions, you MUST make the same change to:
      - google-http-client-assembly/android-properties (make the filenames match the version here)
      - google-oauth-java-client/pom.xml (versions must match)
      - google-oauth-java-client/google-oauth-client-assembly/android-properties (make the filenames match the version here)
      - google-api-java-client/pom.xml (versions must match)
      - google-api-java-client/google-api-client-assembly/android-properties (make the filenames match the version here)
      - Internally, update the default features.json file
    -->
    <project.http-client.version>1.27.1-SNAPSHOT</project.http-client.version><!-- {x-version-update:google-http-client-parent:current} -->
    <project.http-client.version>1.28.1-SNAPSHOT</project.http-client.version><!-- {x-version-update:google-http-client-parent:current} -->
