Rename a symbol across the repo in Groovy with Atlas in 2026

Updated 6 min read

To rename a function, class, or constant across your Groovy repository in 2026, Atlas combines its lsp tool for authoritative references, grep for non-code occurrences, and edit for precise, permission-gated changes, ensuring your build.gradle and Spock specifications are updated correctly before Gradle builds.

How does Atlas accurately rename Groovy symbols across a repository?

Atlas ensures accurate Groovy symbol renames by combining 2 powerful search methods: lsp for compiler-aware references and grep for non-code occurrences. This hybrid approach, crucial in 2026, prevents the common pitfalls of naive find-and-replace, especially in complex build.gradle scripts or Spock specifications.

Atlas leverages a sophisticated hybrid approach to accurately identify all occurrences of a Groovy symbol. It first employs the lsp tool's findReferences operation, which uses tree-sitter to parse the Abstract Syntax Tree (AST) of your Groovy code. This provides an authoritative list of declarations and usages for classes, methods, and constants, ensuring compiler-aware precision that blind text searches miss. For instance, renaming a method `myUtilityMethod` in `src/main/groovy/com/example/MyService.groovy` will correctly identify all call sites, even those in Spock specifications like `src/test/groovy/com/example/MyServiceSpec.groovy`. Simultaneously, Atlas runs grep for the old symbol name to catch occurrences outside the type system, such as strings in comments, documentation, or configuration files like `build.gradle` or `Jenkinsfile`. This dual strategy ensures comprehensive coverage, preventing missed references or false positives that could corrupt your Groovy codebase. Atlas builds its code index with local Ollama embeddings, keeping your Groovy project's details secure.

What are the concrete steps to rename a Groovy symbol with Atlas?

Executing a Groovy symbol rename with Atlas involves a 3-stage process: identifying references, applying mechanical changes, and verifying. Atlas uses its edit tool with replaceAll for the mechanical part, ensuring that changes are applied consistently across your build.gradle files and Spock tests, all within a permission-gated workflow.

Once Atlas has compiled a comprehensive list of references, it proceeds with the mechanical renaming using its edit tool. For the majority of code changes, Atlas utilizes edit with the replaceAll operation, which applies the new symbol name where the match is unambiguous per file. This is crucial for Groovy projects, where symbols might appear in various contexts, from standard `.groovy` files to `build.gradle` scripts defining tasks or dependencies. For example, if you're renaming a constant `DEFAULT_TIMEOUT` used in a Groovy DSL closure within `build.gradle`, Atlas will precisely target and update it. The edit tool is designed to prevent silent corruption: if it encounters a single occurrence that could be ambiguously matched, it will throw a `Found multiple matches for oldString` error, requiring you to add more context or explicitly opt into replaceAll for that specific instance. This ensures that every change to your Groovy code, including @Grab dependencies or shared pipeline libraries, is intentional and verified.

How does Atlas ensure safety and review for Groovy refactoring?

Atlas prioritizes safety and review for Groovy refactoring, offering multiple layers of protection before any file is modified. Every Atlas tool call is permission-gated, and a read-only plan agent drafts changes, presenting a unified diff for approval. This ensures your Spock (gradle test) suite and Spotless formatting are respected in 2026.

Atlas integrates robust safety and review mechanisms into every Groovy refactoring workflow. Before any lsp, grep, edit, or bash tool call is executed, Atlas consults its permission-gated rules (allow, ask, deny), ensuring you maintain full control over the process. The initial phase involves a read-only plan agent that drafts the entire refactoring strategy, which you can review. Once approved, Atlas switches to a build agent to execute the plan. For every file edit, Atlas computes a unified diff, presenting it for your explicit approval before writing changes to disk. This allows you to meticulously inspect every modification to your Groovy source files, `build.gradle`, or `Jenkinsfile`. After the mechanical renames, Atlas prompts you to run `bash ./gradlew test`, executing your Spock specifications to verify that the refactor hasn't introduced regressions. It then performs a final grep for the old symbol name to prove zero remaining hits. Finally, Atlas can apply Spotless with the Groovy formatter to all touched files, maintaining your project's code style. All file changes are snapshotted as Git patches, providing an easy rollback mechanism.

Step by step

  1. 01Ask Atlas to lsp findReferences on your Groovy symbol (e.g., a method in `src/main/groovy/com/example/MyClass.groovy`).
  2. 02Instruct Atlas to grep for the old symbol name across your repository, including `build.gradle` and `Jenkinsfile` for non-code occurrences.
  3. 03Approve Atlas's plan to edit files, using replaceAll for unambiguous matches of the old Groovy symbol name.
  4. 04Review the unified diff presented by Atlas for all proposed changes to your Groovy files.
  5. 05Allow Atlas to run `bash ./gradlew test` to execute your Spock specifications and compile your Groovy project.
  6. 06Ask Atlas to grep for the old symbol name one final time to confirm zero remaining hits in your Groovy codebase.
  7. 07Permit Atlas to apply Spotless with the Groovy formatter to any touched files, ensuring code style consistency.
  8. 08Approve Atlas to stage and create a Git commit for the refactoring.

Frequently asked questions

Can Atlas rename a Groovy method used in a build.gradle script?
Yes, Atlas can rename Groovy methods and properties used within build.gradle scripts, including Groovy DSL closures, by combining lsp for code references and grep for script-specific usages.
How does Atlas handle Groovy symbols in Jenkinsfiles?
Atlas handles Groovy symbols in Jenkinsfiles by using grep to find occurrences in pipeline scripts and edit to apply changes, ensuring consistency even in non-standard Groovy contexts.
What if Atlas finds multiple matches for a Groovy symbol during a rename?
If Atlas's edit tool finds multiple ambiguous matches for a Groovy symbol within a single file, it will throw an error, preventing silent corruption. You must provide more context or explicitly opt into replaceAll.
Does Atlas run Spock tests after a Groovy refactor?
Yes, Atlas can run `bash ./gradlew test` to execute your Spock specifications and compile your Groovy project behind a permission prompt, verifying the refactor's integrity before committing.
How does Atlas ensure Groovy code style is maintained after a rename?
Atlas can apply Spotless with the Groovy formatter to any files it touches during a rename, ensuring that your project's defined code style is consistently maintained.
Can I roll back a Groovy symbol rename performed by Atlas?
Yes, Atlas snapshots file changes as Git patches, allowing you to easily diff and roll back any edits made during a Groovy symbol rename if needed.
Does Atlas support Groovy @Grab dependencies during refactoring?
Atlas builds its code index by reading your Groovy DSL closures and @Grab dependencies, allowing it to understand and refactor symbols correctly within projects using dynamic dependency management.
Is Atlas's Groovy refactoring safe for proprietary code?
Yes, Atlas can build its code index with local Ollama embeddings, keeping your proprietary Groovy code off third-party servers, and every tool call is permission-gated for security.
