Generic Checkout scm step in pipeline does not support the accurev scm.
Can you add the support for this SCM as part of generic checkout scm step
Currently in progress.
Added in 0.7.10
Can you please update accurev scm in compatible scm list supported by pipeline plugin.
Will be useful for people who need this in future.
