Artifact test1:war: Error during artifact deployment. See server log for details.

Artifact deployment error in test1:war typically occurs when there's a problem while deploying a WAR (Web Application Archive) file to a server, such as Apache Tomcat or a similar web application container. This error usually indicates that the server is unable to complete the deployment process due to various reasons, which might include:

1. Invalid or missing dependencies: The WAR file may be dependent on other libraries that are not present in the server's classpath.
2. Configuration issues: Incorrect server configuration, like incorrect context path, servlet mapping, or security settings, can lead to deployment errors.
3. Class loading problems: If there's a conflict between classes or resource files within the WAR, it could cause issues.
4. Server resource limitations: Insufficient memory or disk space, or reaching max number of deployed applications, can prevent successful deployment.
5. Runtime exceptions: There could be a runtime issue in the application code that surfaces during deployment.

To resolve this error, you should check the server logs for detailed information about the specific error, which will usually provide more context and steps to fix the issue. Here are some steps to troubleshoot:

1. **Review server logs**: Look for stack traces, error messages, or warnings that can guide you to the root cause.
2. **Check the deployment descriptor**: If you have a `web.xml` file in your WAR, verify that all configurations are correct.
3. **Maven dependencies**: Ensure that all necessary libraries are included and have compatible versions.
4. **Clean and redeploy**: Try cleaning the server's work directory or undeploying the problematic application before redeploying.
5. **Run tests locally**: If possible, deploy the application locally using a development server to isolate the issue from the production environment.
