How are you running Renovate?

Self-hosted Renovate

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

GitLab, Latest from dockerhub

Please tell us more about your question or problem

For one of my projects renovate started to fail on:

 WARN: Error updating branch: update failure (repository=<my-project>, baseBranch=development, branch=renovate/all)

In debug logs i saw interesting log saying:

DEBUG: Updating mysql:mysql-connector-java in pom.xml (repository=<my-project>, baseBranch=development, branch=renovate/update-all)
DEBUG: Unknown value (repository=<my-project>, baseBranch=development, branch=renovate/update-all)
       "depName": "mysql:mysql-connector-java",
       "version": ">8.0.33",
       "currentValue": "8.0.20",
       "newValue": "8.0.33"

Dependency in project is under dependencyManagement in pom.xml and look totally fine

  <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>8.0.20</version>
      <scope>runtime</scope>
  </dependency>

So i excluded mysql-connector from updating using package rule:

{
      matchPackageNames: [
          "mysql:mysql-connector-java"
      ],
      enabled: false
}

And now everything works fine.
Maybe this is a bug or maybe im doing something wrong

Thanks for the minimal reproduction! Makes it much simpler to investigate 💜

It definitely looks like:

DEBUG: Unknown value (repository=losador/38979, baseBranch=main, branch=renovate/all-dependencies)
       "depName": "mysql:mysql-connector-java",
       "version": ">8.0.33",
							     ^^^^^^^^^ this looks at fault
       "currentValue": "8.0.28",
       "newValue": "8.0.33"

Is the issue here, will see if I can debug why version is including the > in

renovate/lib/modules/manager/maven/update.ts

Lines 20 to 25 in d66d265

     let leftPart = fileContent.slice(0, fileReplacePosition);  
   const rightPart = fileContent.slice(fileReplacePosition);

Mind sharing the output of the INFO: Repository started log to indicate the version, please?

Are there any other log lines near this that may be related? It may be best if you can get a minimal reproduction together, so we can validate

I have created minimal reproduction repository https://github.com/losador/38979, and i managed to "simulate" my error using renovate app, here is job id if you can check it out beaca6e9-bd1a-45b5-98a9-fb2718aa9217

Hi there,

Please help this Discussion progress 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:

Read our guide on creating a minimal reproduction.
Go to our minimal reproduction template repository.
Select the Use this template button to create a new repository based on the template.
Work on the reproduction in your own repository. Ensure it's actually minimal (no unnecesary dependencies or config), or it will be rejected by maintainers.
Install the Renovate app to verify that what you say happens (or doesn't happen) reproduces.
Fill out the information in your repository's README.md. What you describe there should reflect what you see in this repo, with the hosted app, and not what you saw in your original repo/environment.
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.
Add a Discussion comment mentioning that the reproduction repo is now available and linked.

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

The Renovate team

In your case, you can use the Renovate CLI at version 41.165.4 to validate this

OK, this has helped track down that this is because the updateType=replacement happens before the updateType=patch, and modifies the file and so Renovate now has an outdated view of it

I've raised #39273 to track the bug fix
