The mettleci datastage create-project command (documented here) fails inexplicably.
Due to a known issue with the DataStage dsadmin command (which is required by datastage create-project) it is not possible to distinguish between...
a DataStage project that already exists, and
a DataStage project that doesn’t exist in the DataStage repository, but for which the associated filesystem directories do exist.
There may be some situations in which this causes the create-project command to fail.
When faced with an inexplicable failure of this nature check to see if the project’s directory structure already exists on the filesystem. If so, and it’s safe to do so, remove the file structure and try again
