Hello Suman,
To the best of my knowledge there is no way to do this natively in GoCD. You could probably fake it by building something that continually checks for failed Stages and triggers the next Stage when it finds one but I question why someone would want to do this.
The way I tend to think about Stages in GoCD is that each one represents a self-contained process that proves that the release candidate passing through it is suitable for production in some way. Once a release candidate passes through all of the Stages in the Pipelines that drive it, we know it is good to release to production. If the candidate fails at any point, though, it will never be released to production so there is not much value in continuing with any Stages after the one that failed.
Could you elaborate a bit on your model and why you would want to run the next Stage even if the current Stage fails?
Regards,
Jason
