ModiaMath has no know versions (although 3 versions released)

ModiaMath has three released versions and all are registered at METADATA. Modia uses ModiaMath and has ModiaMath in its dependencies (in Project.toml/Manifest.toml file). Modia is cloned to .julia/dev, the current environment (.julia/environments/v1.0) is deleted and Julia 1.0.0 is started newly. The following gives an error (log of session):

If first ModiaMath is added, and then Modia, installation is successful:

Can you give a hint how to fix this issues.

Modia depends on the wrong ModiaMath. Specifically, Modia depends on ModiaMath = "80923050-9e1b-11e8-0c9e-c9f8e684994a" (see https://github.com/ModiaSim/Modia.jl/blob/0e3f37fb90a21e9cfe03688367f176a41c9630d1/Project.toml#L12) but the ModiaMath you want is ModiaMath = "67ccffd1-116d-535b-ad39-76a8fd0cbf71" (see https://github.com/JuliaRegistries/General/blob/22b6ce24c45763f52ce8d4a62c8c5b554bc8370b/M/ModiaMath/Package.toml#L2). You should update the uuid in ModiaMath/Project.toml and also the uuid for ModiaMath in Modias [deps] section.

You should also update https://github.com/ModiaSim/Modia.jl/blob/0e3f37fb90a21e9cfe03688367f176a41c9630d1/Project.toml#L2 to match https://github.com/JuliaRegistries/General/blob/22b6ce24c45763f52ce8d4a62c8c5b554bc8370b/M/Modia/Package.toml#L2

Thanks very much. Your suggestion fixed the problem.
