Problem with Julia1.12 sources section in Project.toml

General Usage

1

I’m trying to make use of the new sources section of Project.toml provided in Julia 1.12.

This is in my project https://github.com/MarkNahabedian/PanelCutting.jl.

The only mention of WebScrapingTools is in

[sources]
NahaXMLUtils = {url = "https://github.com/MarkNahabedian/NahaXMLUtils.jl"}
WebScrapingTools = {url = "https://github.com/MarkNahabedian/WebScrapingTools.jl"}

When I start JUlia and use PanelCutting II get an error:

julia
# Long Julia startup banner elided, except for
# Version 1.12.1 (2025-10-17)

I don’t understand why I’m getting this error. WebScrapingTools is not used by PanelCutting.jl. It is only used by a supackage in src/supplier_fetch/. Why is its version compatibility being checked here?

How do I work around this?

Thanks.
