I've been fixing small things on a project and sudendly I started to get this exception and I don't know what's the reason, the issue is there are no lines in the trace that actually lead to something in my code.

Your issue is common when a Grails project suddenly fails with missing dependencies or class loading errors, even if you haven't changed code. This can happen due to dependency resolution issues, such as a corrupted Gradle cache or changes in remote repositories. A typical solution is to refresh your dependencies and clean your build:

./gradlew clean
./gradlew build --stacktrace --refresh-dependencies

This process clears the cache and forces Gradle to re-download all dependencies, which often resolves such errors. If the problem persists, check for any recently added or updated dependencies that may be incompatible with your Grails version, as older plugins or libraries can cause class loading issues or bean instantiation failures.

A message from kapa.ai

When you encounter an exception in a Grails project where the stack trace does not reference your own code, it often indicates a problem in configuration, dependencies, or framework-level code rather than a direct bug in your application logic. This is a common scenario, especially after making changes to configuration files, dependencies, or the Java version. Based on the knowledge sources, here are some steps and considerations to help you debug such issues: 1. Check for Dependency or Plugin Issues Sometimes, dependencies or plugins may become unavailable or incompatible (for example, due to repository changes like the Bintray sunset). This can cause missing classes or unexpected errors, even if you haven't changed your code. Running

gradlew dependencies

can help you identify version mismatches or missing dependencies. If you recently upgraded Grails or plugins, ensure all dependencies are compatible with your Grails version. Also, check if any dependencies are pulling in old or incompatible versions of Grails libraries, as seen in issues where an old

grails-plugin-converters

version caused startup failures in Grails 5+ projects. Removing or updating such dependencies resolved the issue for others [[dependency version issue example](https://stackoverflow.com/a/76924578)]. 2. Configuration Changes Moving configuration between

application.yml

and

application.groovy

, or introducing environment variables, can sometimes lead to subtle misconfigurations that break bean creation or cause missing properties. If reverting changes does not fix the issue, try cleaning your project (

./gradlew clean

), deleting build caches, and ensuring there are no lingering configuration files or environment variables causing conflicts [[configuration issue example](https://stackoverflow.com/q/73621415)]. 3. Java Version Mismatches Changing the Java version (e.g., via jEnv) can break Grails projects, especially older ones, if the new version is not compatible. Even after reverting, sometimes caches or compiled classes remain problematic. Make sure your Java version matches the one supported by your Grails version, and do a full clean build [[Java version issue example](https://stackoverflow.com/q/73621415)]. 4. Framework or Bean Initialization Errors If the stack trace shows errors during bean creation or class introspection (e.g.,

BeanCreationException

,

MissingPropertyException

, or

NoClassDefFoundError

), it often points to a misconfiguration or a missing/incompatible dependency, not a direct bug in your code. For example, using deprecated configuration options or having a plugin that references a class removed in a newer Grails version can cause such errors [[bean creation/config issue example](https://stackoverflow.com/q/73621415)]. 5. Debugging Steps - Clean and rebuild your project. - Run with

--stacktrace

and

--info

or

--debug

flags for more detailed logs. - Check for any recent changes in dependencies, plugins, or configuration. - If possible, revert to a previous working state and reapply changes incrementally to isolate the cause. Summary: When the stack trace doesn't reference your code, focus on recent changes to dependencies, configuration, or environment (like Java version). Clean your project, check for dependency mismatches, and review configuration files for deprecated or incorrect settings. If the problem persists, try to isolate the change that introduced the issue by reverting or reapplying changes step by step. If you can share the specific exception message and stack trace, it may be possible to provide more targeted advice. But based on the knowledge sources, these are the most common causes and steps to resolve such issues in Grails projects.
