#18561 (comment)

This is an issue that we see happening a lot on CI. Retry the build normally fixes it .. But if you find out what causes it , that would be awesome.

See... I pretend to play cavalry and save the lady in trouble...

Notes to future me (even older than today):

Microsoft.Common.CurrentVersion.targets
error MSB3027: Could not copy "obj\Release\
error MSB3021: Unable to copy file "obj\Releas
Exceeded retry count of 10. Failed.
The requested operation cannot be performed on a file with a user-mapped section open.

Similar approach:

  <ItemGroup>
    <!-- There isn't an actual dependency here, but we can only build one 'gradlew' project
         at a time, and adding <ProjectReference> between them ensures they run sequentially. -->
    <ProjectReference Include="..\manifestmerger\manifestmerger.csproj" ReferenceOutputAssembly="False" />
  </ItemGroup>

Issues Fixed

Unreported CI transient errors, occurring frequently on AzDO with voodoo solves-all workaround called "restart build".
