Process Finished with Exit Code 1 – Spring Boot error

When a Spring Boot application exits with exit code 1, it typically indicates an error occurred during the execution of the application. The exit code value of 1 is commonly used to denote a general error.

To diagnose and fix the error, you need to determine the cause. Here are some possible reasons for encountering an exit code 1 error in Spring Boot:

  1. Application Configuration Issue: Check if your application’s configuration files (e.g., application.properties or application.yml) have any incorrect or missing settings. Make sure all the required properties are properly configured.
  2. Dependency Issue: Verify that your application’s dependencies are resolved correctly. Check your build configuration (e.g., pom.xml file for Maven or build.gradle file for Gradle) and ensure that the required dependencies are included and their versions are compatible.
  3. Code Issue: Examine your application’s code for any logic or syntax errors. Look for any exceptions or error messages that might be logged during the application’s execution. Use appropriate logging frameworks (e.g., SLF4J, Logback) to capture and analyze the logs.
  4. Port Conflict: Spring Boot applications use a default port (8080) for running the embedded web server. If another application or process is already using that port, it can cause conflicts and result in an exit code 1 error. In that case, you can try changing the application’s port to an available one.

It’s important to analyze any error messages, stack trace, or log outputs that are produced when the exit code 1 error occurs. These messages can provide valuable information about the specific cause of the error.

Here is an example of a log message that might be displayed when a Spring Boot application exits with exit code 1: 

    Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
    2022-01-01 10:00:00.123 ERROR 12345 --- [main] o.s.b.d.LoggingFailureAnalysisReporter    : 
    ***************************
    APPLICATION FAILED TO START
    ***************************
  
    Description:
  
    Field exampleField in com.example.MyService required a bean of type 'com.example.SomeBean' that could not be found.
  
    Action:
  
    Consider defining a bean of type 'com.example.SomeBean' in your configuration.

In this example, the error message states that a required bean (SomeBean) could not be found. The suggested action is to define a bean of that type in the application’s configuration.

Remember to review your entire application code, configuration, and any supporting libraries or frameworks to identify and resolve the specific cause for your Spring Boot application’s exit code 1 error.
