   To resolve the issues you're facing with connecting to your JIRA cloud 
instance and the errors in your Jenkins pipeline, follow these steps:
   
   ### JIRA Cloud Connection
   
   1. **Endpoint URL**: Ensure the endpoint URL is in the correct format and 
ends with a `/`. For JIRA Cloud, it should be something like 
`https://your-company.atlassian.net/rest/`.
   
   2. **Authentication**: Use your email and an API token for authentication. 
Here is an example of how to set these fields:
   
   ```tsx
   <Block
     style={{ marginTop: 8, marginBottom: 0 }}
     title="Endpoint URL"
     description={
       <>
         {version === 'cloud'
           ? 'Provide the Jira instance API endpoint. For Jira Cloud, e.g. 
https://your-company.atlassian.net/rest/. Please note that the endpoint URL 
should end with /.'
           : ''}
       </>
     }
     required
   >
     <Input
       style={{ width: 386 }}
       placeholder="Your Endpoint URL"
       value={values.endpoint}
       onChange={handleChangeEndpoint}
     />
   </Block>
   
   {version === 'cloud' && (
     <>
       <Block title="E-Mail" required>
         <Input
           style={{ width: 386 }}
           placeholder="Your E-Mail"
           value={values.username}
           onChange={handleChangeUsername}
         />
       </Block>
       <Block
         title="API Token"
         description={
           <ExternalLink link={DOC_URL.PLUGIN.JIRA.API_TOKEN}>Learn about how 
to create an API Token</ExternalLink>
         }
         required
       >
         <Input
           style={{ width: 386 }}
           placeholder={type === 'update' ? '********' : 'Your PAT'}
           value={values.password}
           onChange={handleChangePassword}
         />
       </Block>
     </>
   )}
   ```
   
   Ensure that:
   - The `endpoint` field is correctly set to your JIRA Cloud instance URL.
   - The `username` field contains your email.
   - The `password` field contains your API token.
   
   ### Jenkins Pipeline Errors
   
   For the "unsupported protocol scheme" and "unexpected status code 404" 
errors in your Jenkins pipeline, you can modify the `execCloneCommand` function 
to handle these specific errors. Here is an example:
   
   ```go
   func (g *GitcliCloner) execCloneCommand(cmd *exec.Cmd) errors.Error {
        stdout, err := cmd.StdoutPipe()
        if err != nil {
                g.logger.Error(err, "stdout pipe error")
                return errors.Default.New("stdout pipe error")
        }
        stderr, err := cmd.StderrPipe()
        if err != nil {
                g.logger.Error(err, "stderr pipe error")
                return errors.Default.New("stderr pipe error")
        }
        combinedOutput := new(strings.Builder)
        stdoutScanner := bufio.NewScanner(stdout)
        stdoutScanner.Split(bufio.ScanLines)
        stderrScanner := bufio.NewScanner(stderr)
        stderrScanner.Split(bufio.ScanLines)
        done := make(chan bool)
        go func() {
                for stdoutScanner.Scan() {
                        combinedOutput.WriteString(fmt.Sprintf("stdout: %s\n", 
stdoutScanner.Text()))
                }
                done <- true
        }()
        go func() {
                for stderrScanner.Scan() {
                        combinedOutput.WriteString(fmt.Sprintf("stderr: %s\n", 
stderrScanner.Text()))
                }
                done <- true
        }()
        if e := cmd.Start(); e != nil {
                g.logger.Error(e, "failed to start\n%s", 
combinedOutput.String())
                return errors.Default.New("failed to start")
        }
        <-done
        <-done
        err = cmd.Wait()
        if err != nil {
                g.logger.Error(err, "git exited with error\n%s", 
combinedOutput.String())
                if strings.Contains(combinedOutput.String(), "stderr: fatal: 
error processing shallow info: 4") ||
                        strings.Contains(combinedOutput.String(), "stderr: 
fatal: the remote end hung up unexpectedly") {
                        return ErrNoData
                }
                if strings.Contains(combinedOutput.String(), "stderr: fatal: 
repository not found") ||
                        strings.Contains(combinedOutput.String(), "unexpected 
status code 404") {
                        return errors.Default.New("repository not found (404)")
                }
                return errors.Default.New("git exit error")
        }
        return nil
   }
   ```
   
   This code checks for the "unexpected status code 404" error and handles it 
by returning a specific error message, which will help you identify and address 
the issue in your Jenkins pipeline 
<sup>[[1]](https://github.com/apache/incubator-devlake/blob/main/config-ui/src/plugins/register/jira/connection-fields/auth.tsx)</sup><sup>[[2]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/gitextractor/parser/clone_gitcli.go)</sup>.
   
   ### Environment Variables for Jenkins
   
   Ensure that the following environment variables are set for Jenkins to work 
seamlessly with `incubator-devlake`:
   
   ```plaintext
   JENKINS_ENDPOINT=
   JENKINS_USERNAME=
   JENKINS_PASSWORD=
   ```
   
   Additionally, make sure other core configurations such as `PLUGIN_DIR`, 
`DB_URL`, and `PORT` are properly set as per your setup requirements 
<sup>[[3]](https://github.com/apache/incubator-devlake/blob/main/devops/releases/lake-v0.11.0/env.example)</sup><sup>[[4]](https://github.com/apache/incubator-devlake/blob/main/devops/releases/lake-v0.10.0-beta1/env.example)</sup><sup>[[5]](https://github.com/apache/incubator-devlake/blob/main/devops/releases/lake-v0.8.0/env.example)</sup><sup>[[6]](https://github.com/apache/incubator-devlake/blob/main/devops/releases/lake-v0.7.0/env.example)</sup>.
   
   By following these steps, you should be able to resolve the connection 
issues with your JIRA cloud instance and the errors in your Jenkins pipeline.
