Description

#540

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Test-only changes (no production code changes)

Testing Checklist

Black-Box Testing Requirements

• Tests follow black-box testing approach: verify behavior through observable outputs (logs, C8 API queries, real-world skip scenarios)
• Tests DO NOT access implementation details (DbClient, IdKeyMapper, ..impl.. packages except logging constants)
• Architecture tests pass (ArchitectureTest validates these rules)

Test Coverage

• Added tests for new functionality
• Updated tests for modified functionality
• All tests pass locally

Architecture Compliance

Run architecture tests to ensure compliance:

mvn test -Dtest=ArchitectureTest

If architecture tests fail, refactor your tests to use:

• LogCapturer for log assertions
• camundaClient.new*SearchRequest() for C8 queries
• Real-World skip scenarios (e.g., migrate children without parents)

Documentation

• Updated TESTING_GUIDELINES.md if adding new test patterns
• Added Javadoc comments for public APIs
• Updated README if user-facing changes

Checklist

• Code follows project style guidelines
• Self-reviewed the code
• Added comments for complex logic
• No new compiler warnings
• Dependent changes have been merged

Pull request overview

This PR adds execution listener migration example code to both Camunda 7 and Camunda 8 code-examples modules, and fixes configuration issues in the Camunda 8 Spring Boot example project. The changes demonstrate how Camunda 7 execution listeners migrate to Camunda 8 JobWorkers, providing a complete working example with tests and REST endpoints.

Changes:

• Added execution listener example files for both Camunda 7 and Camunda 8 (BPMN, Java implementation, controller, tests)
• Fixed Camunda 8 example to use spring-boot-starter-web instead of spring-boot-starter (required for REST controllers)
• Added missing test scope to camunda-process-test-spring dependency
• Renamed Camunda 7 external task worker subscriptions to unique names to prevent conflicts
• Deleted unnecessary Maven wrapper configuration from camunda-8 example module
• Added Camunda 7 external task client configuration in application.yaml

👍 Looks good.

[yanavasileva]

❓ Do we want to delete mvnw* in camunda-8 directory too?

[venetrius]

👍 Removed files

[yanavasileva]

🙃 Maybe move dependencyManagement section before dependencies, the pom is a bit chaotic at the moment.

[venetrius]

👍 Cleaned up the pom.xml file.
