1.11 regression: source file does not contain a module declaration

[aplavin]

MWE:

(@v1.11) pkg> activate --temp
(jl_YdCmZR) pkg> add VOTables@0.1.16
julia> using VOTables
Precompiling VOTables...
Info Given VOTables was explicitly requested, output will be shown live 
ERROR: LoadError: Package VOTables [3abbdab7-df67-4801-8590-8effec53f469] source file /Users/aplavin/.julia/packages/VOTables/H54Mn/src/VOTables.jl does not contain a module declaration.

I do

@doc Base.read(joinpath(dirname(@__DIR__), "README.md"), String) module VOTables

in the package file (didn't know README would be shown anyway!), likely that causes the issue with module detection.
I'll probably remove this line in the next VOTables version, but it seems a bug in Julia anyways.

Everything worked on 1.10, so this is 1.11 regression (thanks @fatteneder for fixing the title!).

[fatteneder]

Probably caused by #51635.

[IanButterworth]

The fix is marked for backport but didn't make it into 1.11.0 #55824

Can you confirm that it doesn't happen on master/nightly?

[giordano]

Can you confirm that it doesn't happen on master/nightly?

It happens for my on d4987a3

[IanButterworth]

I see a different error on master

Ah, I saw there was an error when add-ing the package, wasn't expecting to be a different one!

[IanButterworth]

I've backported #55824 to #56025 so that should be sufficient. Worth testing though.

[IanButterworth]

Closing given the fix was on #56025
