Okay almost fixed.

Error: module issue2051_fail from file /var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/issue2051_fail.d conflicts with another module issue2051_fail from file /var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T//issue2051_fail.d

Okay this looks like a compiler error now, rather than purely a dub issue.

Interesting part of the -v output from dub:

Look at that, it indeed is adding it twice.

[rikkimax]

Its happening at some time during Project.addBuildSettings

[rikkimax]

As of https://github.com/dlang/dub/blob/master/source/dub/dub.d#L474 path is wrong. Its double slashes for file as if it was needing escaping. Weird.

[rikkimax]

Okay so the problem isn't in loadSingleFilePackage, that means its something very close to the main function associated with commandline.d hum

[rikkimax]

The problem isn't dub...

This should be good to go now!
