test_gdasapp_C96_gcafs_cycled_gcdas_fcst_202112201200 failed during stable-nightly testing on Dogwood and Hera with the following error (taken from Dogwood):

The 20211220 12Z cycle is the first half cycle of the C96_gcafs_cycled case. A check of gcdas_fcst dependencies in C96_gcafs_cycled.xml shows

<dependency>
        <and>
          <or>
            <and>
              <taskdep task="gcdas_sfcanl"/>
              <taskdep task="gcdas_aeroanlfinal"/>
            </and>
            <taskdep task="gcdas_stage_ic"/>
          </or>
            <taskdep task="gcdas_prep_emissions"/>
        </and>
</dependency>

The first half cycle gcdas_fcst depends on gcdas_stage_ic and gcdas_prep_emissions. GDASApp tests/gw-ci/CMakeLists.txt only includes the gcdas_prep_emissions dependency for the full cycle gcdas_fcst. This dependency needs to be added to the half cycle gcdas_fcst.

This issue is opened to document this problem and its resolution.
