Replit deployment

.replit Config File Invalid on Replit

Replit displays config errors or your custom run command doesn't execute. The .replit configuration file has syntax errors or missing required fields.

The .replit file controls how your app builds and runs on Replit.

Error Messages You Might See

Invalid .replit configuration Failed to parse .replit file run: command not found
Invalid .replit configurationFailed to parse .replit filerun: command not found

Common Causes

  1. TOML syntax errors (missing quotes, invalid characters)
  2. Missing 'run' key for deployment command
  3. Wrong build tool command (e.g., mvn instead of ./gradlew)
  4. File encoding issues or line endings
  5. Incorrect module path for multi-module projects

How to Fix It

Validate .replit TOML syntax using a TOML linter. Ensure 'run' command is correct (./gradlew bootRun for Gradle projects). For Spring Boot, use './gradlew bootRun' or java -jar. Set appropriate working directory if needed. Verify file is saved as plain text with Unix line endings.
