duplicate id error

[kevinohara80]

I have an existing test class called MyExt_Test.cls. When watching with dmc watch, the tooling api attempts to deploy this file but it fails to match it's id and throws a duplicates value on record error.

This issue doesn't happen if you watch while forcing the deploy with the metadata api (i.e. dmc watch --meta)
