HOWTO: support gradle.properties for dependency version variables?

How are you running Renovate?

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

I have a Gradle project that contains a deps.gradle file. This file has the following definition:

ext.libraries = [
        example                       : [
                dependencies.create("org.example.org:example:$exampleVersion") {
                    exclude(group: "org.slf4j", module: "slf4j-api")
                }
        ]
]

Various sub projects reference this as: implementation libraries.example. Then, there is a gradle.properties file that has exampleVersion=1.2.3.

I have tried various forms of regex matchers to capture the dependency and link it to the right version variable, but from what I can gather, this scenario is not supported by renovate. Is that correct? Do you see a way I could support this form of configuration?

PS Switching to Gradle's version catalog at the moment is not possible, since the catalog does not centrally support exclusions.

Hi there,

Get your discussion fixed faster by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the minimal reproduction in your own repository.
5. Fill out the information in your repository's README.md.
6. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.

If you need help with running renovate on your minimal reproduction repository, please refer to our Running Renovate guide.
Good luck,

The Renovate team
