I'm using gradle plugin v2. I have a project with sources and also some sub-projects. I'm using dependencies {} to aggregate documentation from the sub-projects but I also want to see the documentation for my root project. It doesn't seem to work by default. More in 🧵

[Robert Jaros]

I'm trying to use something like this:

dependencies {
    dokka(rootProject)
    dokka(project(":subproject1"))
    dokka(project(":subproject2"))
    ...
}

and it almost works, but the index for the root project docs shows list of subprojects instead of packages. Can I somehow fix it? Is there a better solution?

[Robert Jaros]

I know I could create yet another subproject for my root sources, but I don't want to refactor the whole project.

[Adam Semenenko]

Hmm, interesting, this should work. Can you share a screenshot of the current result? Does DGPv1 produce what you want?

[Robert Jaros]

I don't know about DGPv1 because I've never used it in my project in this configuration (Dokka 1 was not working for me with standard config). Now I'm already on v2.

A screenshot

If I click any module link other than the first, I will see the list of packages in that module.

[Robert Jaros]

But I can't see the list of packages for the first ("kvision") module because it is the main "index.html" and it contains the list of modules.

[Robert Jaros]

I can see the packages in the left panel only

This is my configuration: https://github.com/rjaros/kvision/blob/master/build.gradle.kts#L148

[Adam Semenenko]

I tried modifying the multimodule example to aggregate in the root project instead of the :docs subproject, and I get 404s when I try looking in the root project code, and I can see in the URL I see a double slash // so I think the name isn't being set correctly.

[Adam Semenenko]

Can you try adding this to the root project?

dokka {
    modulePath = "root"
}

[Robert Jaros]

Almost perfect 🙂

[Robert Jaros]

The only problem is that the root module is now listed at the end in the left panel.

[Robert Jaros]

Can I use other name instead of "root" ("a_root") to make it first ?

[Adam Semenenko]

yeah, almost any path is fine, just check the kdoc to learn more :)

[Adam Semenenko]

I think modulePath = "kvision" would work

[Robert Jaros]

Thank you!

[Adam Semenenko]

np, thanks for the report! It looks like a bug and might be fixable

it looks like there's a bug which removes a path element from the URL, so when opening the page locally the html dir is missing
