Solving NoSuchMethodError in CDI with Weld in Java SE

If you're working with Context and Dependency Injection (CDI) using Weld in Java SE and are facing the frustrating NoSuchMethodError during the initialization of your container, you're not alone. This article will walk you through the steps to resolve this issue effectively.

Understanding the Problem

This error typically indicates that there is a missing dependency or a version mismatch in your project's configuration, specifically relating to the Jandex library.

Investigating the Dependencies

While this is essential, it seems something else is amiss—most likely related to how your Hibernate and Jandex dependencies are defined.

Proposed Solution

The resolution involves two critical steps:

Excluding the Jandex Dependency from Hibernate

Adding an Individual Jandex Dependency

Step 1: Exclude Jandex from Hibernate Dependency

By performing this exclusion, you are preventing the conflicting version of Jandex from being included with Hibernate.

Step 2: Add an Individual Jandex Dependency

After excluding Jandex from Hibernate, you must explicitly add a compatible version of Jandex to your project. Here is how to include it:

Conclusion

By following the steps outlined above, you should resolve the NoSuchMethodError that you encountered during CDI initialization. Ensuring that your dependencies are correctly configured and compatible is key to a smooth development experience.

If you run into any further issues, make sure to check your dependency versions and ensure that no other libraries are conflicting.

Happy coding!
