test_renovate_40690

Simple Maven test project for testing Renovate issue #40690

Current behavior

The configuration of

{
  "baseBranches": [ "main/integration", "1000XX/integration" ],
  "branchPrefix": "",
  "additionalBranchPrefix": "{{lookup (split baseBranch '/') 0}}/update/renovate-",
  "useBaseBranchConfig": "merge",
  ...

Is creating the following wrong branch names:

• 1000XX/integration-1000XX/update/renovate-major-maven-versions
• 1000XX/integration-1000XX/update/renovate-maven-versions
• main/integration-main/update/renovate-major-maven-versions
• main/integration-main/update/renovate-maven-versions

Expected behavior

The template in additionalBranchPrefix should exract from the given baseBranches names the parts "main" and "1000XX" respectively and create branch names as:

• 1000XX/update/renovate-major-maven-versions
• 1000XX/update/renovate-maven-versions
• main/update/renovate-major-maven-versions
• main/update/renovate-maven-versions

Project Overview

This project is designed to test the branch naming behavior when using additionalBranchPrefix in Renovate configuration with template expressions involving baseBranch.

Project Structure

This is a simple Maven project with:

• 3 dependencies to be updated by Renovate:

  • JUnit 5 (version 5.9.3)
  • Log4j 2 (version 2.20.0)
  • Mockito (version 5.3.1)

• Simple Java classes:

  • Calculator.java - A basic calculator class using Log4j for logging
  • CalculatorTest.java - JUnit 5 tests using Mockito extension

Issue Being Tested

The issue relates to branch naming when using additionalBranchPrefix with template expressions like:

"additionalBranchPrefix": "{{lookup (split baseBranch '/') 0}}/update/renovate-"

The expected behavior is to extract the first part of the base branch name and use it as a prefix. However, the reported issue shows that the full base branch name is being concatenated incorrectly.

Renovate Configuration

The renovate.json file contains the configuration that tests the issue with:

• baseBranches: ["main"]
• branchPrefix: ""
• additionalBranchPrefix: "{{lookup (split baseBranch '/') 0}}/update/renovate-"

GitHub Actions Workflow

The .github/workflows/renovate.yml file provides a manually triggered workflow to run Renovate bot with options for dry-run mode.

Building the Project

mvn clean compile test

Running Renovate

Manually trigger the "Renovate" workflow from the GitHub Actions tab to test the branch naming behavior.
