I can not seem to get an app installed using the current julia 1.12 beta, if there are any Stdlibs in the dependencies. This works:

`src/PapisImport.jl`:

```julia
module PapisImport

export main

function (@main)(args)
    @info args
end

end

```

`Project.toml`

```toml
name = "PapisImport"
uuid = "69ff6faf-3e79-4e92-b1a9-17ae241e1550"

[apps.papim]

```

```julia-repl
shell> papim
Precompiling PapisImport finished.
  1 dependency successfully precompiled in 1 seconds
[Info: String[]

```

But if I add any package dependencies, I get errors when trying to load the app. Eg if I do `]add MiniLoggers`, then put `using MiniLoggers` inside the module, I get:

```julia
(PapisImport) pkg> st
Project PapisImport v0.1.0

ERROR: The following 1 direct dependency failed to precompile:

Failed to precompile PapisImport [69ff6faf-3e79-4e92-b1a9-17ae241e1550] to "/home/kevin/.julia/compiled/v1.12/PapisImport/jl_wOiceF".
ERROR: LoadError: ArgumentError: Package PapisImport does not have MiniLoggers in its dependencies:

I can do

```julia-repl

I would probably open an issue in Pkg.jl

I just want to make sure I’m not doing something dumb first 😛
