This behavior does not occur in go 1.14.2, it appears that this line https://github.com/revel/cmd/blob/master/revel/run.go#L78 is passing so that the conversion from the third argument is attempted and fails. Please either upgrade Go or use the flags to prevent this from occurring like

revel run -a my-app1 -m dev

[goevexx]

It also occurs in 1.14.6

$ revel run my-app dev

go version go1.14.6 windows/amd64

revel run -a my-app -m dev works instead
