At present, because Dependaroo can open multiple pull requests to update multiple dependencies, upon merging one of the pull requests there will be a merge conflict in the [pom.xml/build.gradle.kts/etc.] that requires manually rebasing before it can be merged.
As an example, Dependabot on GitHub does this automatically. When a merge conflict is detected, the pull request will have an info banner shown that says "Dependabot is rebasing this pull request". Afterwards, you can then merge when ready.
