I used to deploy my projects to Cloud Run with continuously deploy from a bitbucket repository.
But I found that Cloud Run removed this option a few days ago?
How should I continuously deploy my projects from a bitbucket repository now?
now i can only build the project manually
Yes.BitBucket repository being no longer available for Cloud Run continuous deployment. Now, only GitHub remains as a Repository Provider. The Bitbucket section was removed from the document also.
FYI, Cloud Run's "continuous deployment" setup has always been a UI shortcut on top of Cloud Build Triggers.

You can use a Cloud Build Trigger. Refer to document and blog on how to deploy to cloud run.
Incase if you still want to continue with bitbucket from cloud run, you may consider raising a issue tracker by describing your request in detail.
