   To address the issue where the "Git" task fails on subsequent runs due to 
the "folder already exists" error, you can modify the `Git` function to check 
if the directory already exists before attempting to clone the repository. If 
the directory exists, you can skip the cloning process. Here is a modified 
version of the `Git` function:
   
   ```go
   func Git(taskCtx plugin.SubTaskContext) errors.Error {
       logger := taskCtx.GetLogger()
       data := taskCtx.GetData().(*DbtTaskData)
       if data.Options.ProjectGitURL == "" {
           return nil
       }
       
       // Check if the directory already exists
       projectDir := "your_project_directory" // Replace with the actual 
directory path
       if _, err := os.Stat(projectDir); !os.IsNotExist(err) {
           logger.Info("Project directory already exists, skipping clone.")
           return nil
       }
       
       cmd := exec.Command("git", "clone", data.Options.ProjectGitURL)
       logger.Info("start clone dbt project: %v", cmd)
       out, err := cmd.CombinedOutput()
       if err != nil {
           logger.Error(err, "clone dbt project failed")
           return errors.Convert(err)
       }
       logger.Info("clone dbt project success: %v", string(out))
       return nil
   }
   ```
   
   This code checks if the project directory already exists and skips the 
cloning process if it does, thus preventing the error
