Repo sync with manifest download old version code

Sometimes in order to reproduce the problem, we need to package the code in the Code warehouse the previous few days


Put the manifest file that was packaged for the day into the. repo/manifests/inside of any set of code, assuming this file is named Pre_version.xml
And then execute
Repo Init-m Pre_version.xml
Next we use the order
LL. repo/manifest.xml
Look at the Manifset in the package and see that it's already linked to the pre_version.xml we made


The last time you synchronize code, you can overwrite code that already exists for security
Repo SYNC-CDF--force-sync

The meaning of options such as CDF:

$ repo Help Sync

-C,--current-branch fetch only the current branch from server

-D,--detach detach projects back to manifest revision

-F,--force-broken continue sync even if a project fails to sync

--force-sync overwrite an existing git directory if it needs to
Point to a different object directory. Warning:this
May cause loss of data

Repo Sync's-C parameter downloads only the current branch, speeds up code downloads, and saves hard disk space

The Help form for the Ps:repo command is Repo command [ARGS]
