missing jar files

The issue you're experiencing with missing JAR files from AWS Bluage Artifacts during the build process is a common problem that can occur when working with AWS Blu Age projects. This typically happens due to a few reasons:

1. Access to Blu Age runtime: You need proper access to the Blu Age runtime libraries. These essential JAR files are required for building and executing the modernized code. To resolve this, you should follow the AWS Mainframe Modernization documentation to set up and obtain access to these runtime libraries.

2. Version mismatch: Ensure that you're using the same version of AWS Blu Age for both generating the modernized code and executing it. The version in your development environment should match the one used to build the modernized code. A mismatch can lead to dependency errors.

3. Maven configuration: Verify that your Maven settings are correctly configured to access the necessary repositories for Blu Age dependencies. This may involve updating your Maven settings.xml file to include the correct repository information for Blu Age dependencies.

4. Project build path: Double-check your project's build path in your development environment (like Eclipse) and ensure all required Blu Age libraries are properly included.

To resolve these issues:

1. Follow the AWS Mainframe Modernization documentation to properly set up and gain access to the Blu Age runtime libraries.
2. Verify the version compatibility between your code generation and execution environments.
3. Check and update your Maven configuration to ensure it can access the necessary Blu Age repositories.
4. Review your project's build path and include any missing Blu Age libraries.

If these steps don't resolve the issue, you may need to consult specific workshop documentation or reach out to the AWS Blu Age support team for further assistance.
