Jenkins unable to find build script

This error typically occurs when Jenkins is unable to locate the build script that you have specified in your Jenkinsfile or build configuration.

Here are a few things you can check to resolve this issue:

1. Ensure that the build script is located in the correct directory and has the correct filename and extension.

2. Check that the build script is specified correctly in your Jenkinsfile or build configuration. Make sure that you have specified the correct path to the script and that the script name is correctly spelled.

3. Ensure that the Jenkins user has the necessary permissions to access the build script.

4. Check that the build script is executable. You can do this by running the command "chmod +x <script-name>".

5. Check that the build script is not being blocked by any firewalls or security software.

If none of these solutions work, you may need to further investigate the issue or seek help from your Jenkins administrator or support team.
