How does Atlas handle reflection configuration during a GraalVM symbol rename?

Atlas uses `grep` to identify occurrences of the old symbol name within files like `META-INF/native-image/reflect-config.json`. When the `edit` tool performs the rename, it updates these configuration entries, ensuring that reflective calls continue to function correctly in your GraalVM native-image builds.

Can Atlas rename symbols that are only used in string literals or comments in GraalVM?

Yes, Atlas's `grep` tool is specifically designed to catch occurrences of the old symbol name in string literals, comments, documentation, and other non-code contexts that the language server might miss. This ensures a truly comprehensive rename across your GraalVM project.

What if a rename breaks my `mvn -Pnative test` build?

Atlas allows you to run `atlas bash "mvn -Pnative test"` after the rename. If the build or tests fail, you can review the generated diffs, make further adjustments, or even roll back the changes using Atlas's git patch snapshots.

How does Atlas ensure code style consistency after a rename in GraalVM?

After applying renames, Atlas can execute `atlas bash "mvn spotless:apply"`. This command runs your project's `Spotless` formatter, automatically adjusting the style of any modified files to maintain consistency with your GraalVM project's coding standards.

Does Atlas require an internet connection to perform GraalVM symbol renames?

Atlas can build its code index with local Ollama embeddings, keeping your GraalVM code off third-party servers. While some language server features might benefit from external resources, the core rename workflow can largely operate locally, especially with a local LSP server.

How does Atlas prevent accidental broad replacements during a GraalVM refactor?

The `edit` tool in Atlas enforces uniqueness for single replacements. If it finds "Found multiple matches for oldString" when a precise change is intended, it will error out, requiring you to either provide more context or explicitly opt into a `replaceAll` operation, preventing unintended widespread changes in your GraalVM codebase.

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

Atlas empowers GraalVM developers in 2026 to rename functions, classes, or constants across an entire repository, ensuring every usage is updated, including those missed by naive text searches. It integrates with your existing Maven build and Spotless formatter, providing a robust, terminal-native solution for complex refactoring tasks.

How Atlas renames symbols in GraalVM projects

Atlas renames symbols in GraalVM projects by combining 3 powerful tools: `lsp`, `grep`, and `edit`. This hybrid approach ensures that both type-system references and non-code occurrences, like documentation or configuration, are updated, preventing runtime failures in native-image builds in 2026.

When renaming a symbol within a GraalVM codebase, Atlas first employs the `lsp` tool's `findReferences` operation. This leverages the language server to identify all authoritative callsites and declarations, ensuring type-aware accuracy for Java classes, methods, or fields. Following this, Atlas runs `grep` for the old symbol name. This crucial step catches occurrences outside the compiler's view, such as comments, Javadoc, string literals, or configuration files like `pom.xml` or `reflect-config.json` within `META-INF/native-image`. The `edit` tool then applies the mechanical `replaceAll` operations, ensuring consistency across the entire project. This comprehensive strategy is vital for GraalVM, where reflection and resource paths must be declared precisely to avoid issues in native binaries.

Concrete commands and files for GraalVM symbol renaming

Renaming a symbol in a GraalVM project with Atlas involves specific commands and interacts with key project files. Atlas uses `lsp` to query the language server, `grep` for text matches, and `edit` for modifications, all while respecting your `pom.xml` and `META-INF/native-image` configurations in 2026.

To initiate a symbol rename, you would typically start by asking Atlas to "rename `OldSymbolName` to `NewSymbolName`". Atlas then orchestrates the underlying tools. For instance, it might first execute `atlas lsp findReferences OldSymbolName` to get the precise list of references from the language server. Subsequently, `atlas grep OldSymbolName` would scan the entire repository, including files like `pom.xml` for dependency updates, or `src/main/resources` for resource path changes. The `edit` tool then performs the actual text replacements. For example, if a class `OldService` is renamed to `NewService`, Atlas would update its declaration, all instantiations, and any references in `reflect-config.json` if it were used reflectively. After edits, Atlas can run `atlas bash "mvn -Pnative test"` to validate the changes, ensuring the native-image build remains functional.

Ensuring safety and review during GraalVM refactoring

Atlas prioritizes safety and developer review throughout the GraalVM symbol renaming process. Every proposed change is presented as a unified diff for approval, and the `edit` tool enforces uniqueness for single replacements, preventing unintended corruptions in your 2026 codebase.

Before any changes are written to disk, Atlas computes a unified diff for every file edit and surfaces it for your approval. This allows GraalVM developers to meticulously review each modification, ensuring that the rename is accurate and doesn't introduce regressions, especially critical for native-image builds where subtle issues can lead to runtime failures. The `edit` tool is designed with safety in mind: it refuses ambiguous single replacements. If `edit` finds "Found multiple matches for oldString" when a single occurrence is expected, it will throw an error rather than silently corrupting the file. This forces explicit context or an opt-in to `replaceAll`, preventing accidental broad changes. Furthermore, Atlas drafts a plan in a read-only plan agent and asks for permission before switching to a build agent, providing another layer of control. After changes, Atlas can snapshot file changes as git patches, allowing edits to be easily diffed and rolled back if necessary.

Validating GraalVM renames with testing and formatting

After renaming a symbol in a GraalVM project, Atlas facilitates comprehensive validation using the project's established toolchain. This includes running `mvn -Pnative test` to confirm functionality and applying `Spotless` to ensure code style consistency across the 2026 codebase.

Once Atlas has applied the mechanical renames, the next critical step is validation. Atlas can execute `atlas bash "mvn -Pnative test"` to run your project's full suite of tests, specifically targeting the native-image profile. This ensures that the renamed symbol and its usages are correct and that the application still functions as expected, particularly important for GraalVM's ahead-of-time compilation where runtime reflection or resource issues might only surface during native compilation or execution. Following successful testing, Atlas can also apply the project's formatter by running `atlas bash "mvn spotless:apply"`. This ensures that all modified files adhere to the `Spotless` configuration, maintaining code quality and consistency across the repository. Finally, a post-rename `atlas grep OldSymbolName` confirms that no lingering references to the old symbol remain, providing a definitive check for a complete refactor.

Step by step

01Ask Atlas to rename your GraalVM symbol, for example, "rename `com.example.OldClass` to `com.example.NewClass`".
02Atlas uses the `lsp` tool's `findReferences` operation to get the authoritative callsite list for `com.example.OldClass` from the language server.
03Atlas runs `grep` for `OldClass` to find occurrences outside the type system, such as in comments, documentation, string literals, or `reflect-config.json` within `META-INF/native-image`.
04Atlas applies the mechanical renames using the `edit` tool with `replaceAll` where the match is unambiguous per file, ensuring consistency across your `Maven` project.
05Atlas presents a unified diff for all proposed changes. Review these changes carefully, especially for `pom.xml` or `META-INF/native-image` updates, and approve them.
06Execute `atlas bash "mvn -Pnative test"` to compile your GraalVM project and run its test suite, verifying the renamed symbol's functionality in the native-image context.
07Apply your project's formatter by running `atlas bash "mvn spotless:apply"` to ensure all modified files adhere to code style standards.
08Run `atlas grep OldClass` one last time to confirm zero remaining hits for the old symbol name, ensuring a complete refactor.
