How to solve warning while using custom package with Revise?

Hi,
When I try to use my custom package with Revise.jl, as follows, I am getting warning.

using Revise
using MyPkg

The warning is as follows:

┌ Warning: C:\Users\zac\.julia\packages\Plots\qZHsp\src\Plots.jl\ is not an existing directory, Revise is not watching
└ @ Revise C:\Users\zac\.julia\packages\Revise\S7mrl\src\Revise.jl:489

I started getting this warning after upgrading Julia to version 1.3. Moreover, I reinstalled Plots package. The status of my package is as follows:

Project MyPkg v0.1.0
    Status `C:\Users\z5168736\.julia\dev\MyPkg\Project.toml`

  [37e2e46d] LinearAlgebra

How can I solve this issue?

Thanks in Advance !

Is C:\Users\zac\.julia\packages\Plots\qZHsp\src\Plots.jl\ an existing directory? Your package depot may be corrupted.

My guess is you just need to pkg> up. Most likely you’re using a Manifest.toml file that is appropriate for one Julia version but not 1.3.

@Tamas_Papp : There is two folders inside C:\Users\zac\.julia\packages\Plots folder, BmY79 and qZHsp. How can I check package depot is corrupted or not?

@tim.holy: I removed Revise package and added it again. Then I updated the packages using ]up . But I am getting the same warning.
In your reply, you have mentioned that Manifest.toml may not be appropriate. is it belongs to my custom package or it’s for the julia 1.3 ?

Instead of debugging how and what exactly is corrupted, I would just delete both directories in

C:\Users\zac\.julia\packages\Plots

and the manifest (the global one), start a new session, and do a pkg> resolve.

@Tamas_Papp: I have done this too, But still the same issue. May be I need to reprogram my package again. Thanks for your reply.

Thanking You,
Manu

It’s might be solvable, but without a runnable example I don’t know what to say.

Are you using MAT.jl?

@jaakkor2: Yes, I am using MAT in my package. Will it be the problem?

Now that there is a simple reproducer, hopefully Tim is able to fix the warning :grinning:

@tim.holy: Now, I could make a running example by getting insight from @jaakkor2’s reply.

I simply created a package named TestPkg.

I added two dependencies for this package .

] activate .
add Plots
add MAT
activate
resolve

The file named TestPkg.jl inside ~.julia/dev/TestPkg/src is written as below:

module TestPkg

using Plots, MAT


greet() = print("Hello World!")



function write_mat_file(file_name)
    b = rand(5,5)
    file = MAT.matopen(file_name, "w")
    write(file, "a", b)
    close(file)
end
function plot_img(mat_size)
    test_img = rand(mat_size,mat_size)
    heatmap(test_img)
end
end # module

After that, I used that package by using

using Revise
using TestPkg

and I got the warning as below:

Warning: C:\Users\z5168736\.julia\packages\Plots\qZHsp\src\Plots.jl\ is not an existing directory, Revise is not watching
└ @ Revise C:\Users\z5168736\.julia\packages\Revise\ZOWOa\src\Revise.jl:489

This warning come only when I use Plots and MAT packages together.
