How does Atlas detect if my Quarkus Maven build is waiting for input?

Atlas's bash tool monitors the execution of your Maven command. If the command exceeds its timeout and exhibits behavior consistent with waiting for interactive input, Atlas explicitly identifies this in the shell_metadata block of its output. This prevents you from endlessly waiting for a QuarkusTest or build that is silently blocked.

Can Atlas help if my JUnit 5 (@QuarkusTest) suite is running too long?

Yes, Atlas can help diagnose long-running JUnit 5 (@QuarkusTest) suites executed via ./mvnw test. If the test run exceeds the default timeout, Atlas will report if it's genuinely slow or if a test is blocked, perhaps by an unexpected prompt. You can then adjust the timeout or add non-interactive flags.

What if Atlas suggests a change to my pom.xml or application.properties?

If Atlas proposes changes to your pom.xml or application.properties (e.g., for build-time augmentation), it will first draft a plan in a read-only agent. You will review this plan and then approve a unified diff of the proposed changes before Atlas writes anything to your Quarkus project.

How does Atlas handle Spotless formatting in a Quarkus project?

Atlas can integrate with Spotless for code formatting in your Quarkus project. When Atlas is configured to apply Spotless, it will run the formatter and then present a unified diff of the changes for your review and approval before committing them, ensuring your code style is maintained.

Is Atlas compatible with Quarkus native-image builds?

Yes, Atlas is designed to work with Quarkus native-image constraints. It can help replace runtime reflection with build-time-friendly patterns to ensure your classes survive native-image compilation. Atlas also supports running and diagnosing Maven commands related to native-image builds.

What if I accidentally abort a command in Atlas?

If you manually abort a command running through Atlas's bash tool, the shell_metadata block in the output will clearly state "User aborted the command." This distinct message helps you differentiate your intentional interruption from a command that timed out or was blocked by Atlas.

Does Atlas use local resources for code indexing in Quarkus projects?

Yes, Atlas can build its code index for Quarkus projects using local Ollama embeddings. This means your code stays on your machine, off third-party servers, ensuring privacy and security while Atlas performs hybrid semantic and keyword retrieval fused by reciprocal rank fusion.

Diagnose a hanging or long-running command in Quarkus with Atlas in 2026

Atlas helps Quarkus developers in 2026 efficiently diagnose why a Maven build, JUnit 5 (@QuarkusTest) run, or any script might be hanging or running slowly. By executing commands through Atlas's bash tool, you gain immediate insight into whether a process is silently blocked, waiting for interactive input, or simply taking a long time to complete. This prevents wasted time debugging unresponsive terminals, allowing you to quickly apply the correct fix, such as adding non-interactive flags or increasing a timeout, and get your Quarkus project unstuck.

How Atlas Diagnoses Hanging Quarkus Commands

Atlas provides a robust mechanism for Quarkus developers in 2026 to diagnose unresponsive commands, such as a Maven build or JUnit 5 (@QuarkusTest) execution. It achieves this by racing every command against a configurable timeout, and if the command exceeds this limit, Atlas's bash tool generates a shell_metadata block detailing the exact cause, often identifying silent blocks on interactive input.

When a Quarkus developer executes a command like ./mvnw clean install or ./mvnw test through Atlas's bash tool, Atlas monitors its execution. If the command does not complete within the specified timeout, Atlas intervenes. Instead of simply killing the process, Atlas analyzes the state and provides a clear diagnosis within the shell_metadata block of its output. This is particularly useful for Quarkus projects, where complex build-time augmentation can sometimes lead to unexpected pauses. Atlas explicitly distinguishes between a command that is genuinely slow and one that is silently blocked, perhaps waiting for user input that will never arrive in an automated context. For instance, if a Maven plugin prompts for confirmation without a -B (batch mode) or --no-input flag, Atlas will identify this as a blocked-on-stdin scenario, saving hours of debugging a seemingly frozen terminal. This diagnostic capability is a core part of Atlas's value proposition for modern Quarkus development workflows.

What Quarkus Commands and Files are Involved in Atlas Diagnosis?

Diagnosing a hanging Quarkus command with Atlas involves interacting directly with your project's pom.xml and executing standard Maven commands. For example, running ./mvnw clean install or ./mvnw test through Atlas's bash tool allows Atlas to monitor and report on their execution, providing crucial shell_metadata if a timeout occurs, often within 10 seconds by default.

The primary commands a Quarkus developer will use with Atlas for diagnosis are the standard Maven wrapper commands, such as ./mvnw compile, ./mvnw package, or ./mvnw test for JUnit 5 (@QuarkusTest) runs. These commands are executed via Atlas's bash tool. For instance, atlas bash './mvnw clean install' will run your build. If this command hangs, Atlas will provide output indicating whether it's slow or blocked. If Atlas reports a command is blocked on interactive input, the solution often involves adding non-interactive flags specific to Maven or the underlying tool, such as -B for batch mode, or --no-input. For example, 'atlas bash './mvnw clean install -B''. Atlas also understands the context of your Quarkus project by reading files like pom.xml to identify dependencies like quarkus-bom and application.properties for configuration, though these are not directly modified during the diagnosis process itself. The focus is on the execution of the commands defined within your pom.xml.

Resolving Blocked or Slow Quarkus Commands

Once Atlas diagnoses a hanging Quarkus command, resolving it is straightforward, often requiring a simple adjustment to your Maven command or an increased timeout. If Atlas's shell_metadata indicates a command is blocked on interactive input, such as a JUnit 5 (@QuarkusTest) run, you'll typically re-run it with non-interactive flags like -B or --no-input to prevent prompts, a common fix in 2026.

Atlas's diagnostic message provides clear instructions for resolution. If the shell_metadata block explicitly states that the command is waiting for interactive input, the next step is to re-execute the command with appropriate non-interactive flags. For Maven commands, this often means appending -B for batch mode, or --no-input if a specific plugin supports it. For example, if ./mvnw test was blocked, you might try 'atlas bash './mvnw test -B''. This ensures that the command proceeds without user intervention. If, however, Atlas reports that the command is genuinely slow, the solution is to retry the command with a larger timeout value. Atlas's output will suggest the syntax for this, allowing you to specify a timeout in milliseconds. For instance, 'atlas bash --timeout 60000 './mvnw package'' would allow the command to run for up to 60 seconds. This iterative process, guided by Atlas's precise feedback, quickly unblocks your Quarkus development workflow.

Atlas's Safety and Review for Quarkus Changes

Atlas prioritizes safety and transparency when making any changes to your Quarkus codebase, even during diagnostic workflows. Every Atlas tool call, including those involving Maven commands or Spotless formatting, is permission-gated against allow, ask, and deny rules. Before any modification, Atlas drafts a plan in a read-only agent, ensuring you review and approve the strategy before execution, a critical feature in 2026.

While diagnosing hanging commands primarily involves running and observing, Atlas's broader capabilities for Quarkus development include making code changes. When Atlas proposes to modify your pom.xml, application.properties, or add JUnit 5 (@QuarkusTest) cases with RestAssured, it follows a strict safety protocol. First, Atlas operates with a read-only plan agent, which drafts a detailed strategy without altering any files. This plan is presented for your review and explicit approval. Only after approval does Atlas switch to a build agent to execute the plan. Furthermore, for every file edit, Atlas computes a unified diff, which is surfaced for your approval before any changes are written to disk. This allows Quarkus developers to review exactly what Atlas intends to do, from replacing runtime reflection with build-time-friendly patterns to applying Spotless formatting, ensuring full control and preventing unintended modifications to your project.

Step by step

011: Run your Quarkus command through Atlas's bash tool: Execute your Maven command, such as ./mvnw clean install or ./mvnw test for JUnit 5 (@QuarkusTest), using 'atlas bash 'your_command_here''.
022: Examine the shell_metadata block for diagnosis: If the command times out, Atlas will output a shell_metadata block. Read this block to determine if the command is "waiting for interactive input" or "expected to take longer."
033: If blocked, re-run with non-interactive flags: If Atlas indicates the command is blocked on input, re-execute it with Maven's batch mode (-B) or other non-interactive flags, for example: 'atlas bash './mvnw clean install -B''.
044: If genuinely slow, retry with a larger timeout: If Atlas reports the command is slow, re-run it with an increased timeout value in milliseconds, as instructed: 'atlas bash --timeout 120000 './mvnw package''.
055: Distinguish user aborts from timeouts: If you manually interrupt a command, the shell_metadata will explicitly state "User aborted the command," clearly differentiating it from an Atlas-imposed timeout.
