### Open Spotbugs GUI

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Launch the Spotbugs GUI to review the generated Spotbugs report. This is useful for examining findings in detail.

```bash
mvn spotbugs:gui
```

--------------------------------

### Configure Accept First Connection Strategy (YAML)

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/README.adoc

Use this YAML configuration to enable the 'Accept first connection' SSH host key verification strategy. This strategy remembers the first host key encountered for a Git server.

```yaml
security:
  gitHostKeyVerificationConfiguration:
    sshHostKeyVerificationStrategy: "acceptFirstConnectionStrategy"
```

--------------------------------

### Compile and Test Plugin

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Compile and run automated tests for the plugin using Maven. Ensure Java 11 or Java 17 is used.

```bash
mvn clean verify
```

--------------------------------

### Apply Code Formatting

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Apply code formatting rules maintained by the spotless maven plugin. Run this before submitting a pull request to ensure consistent code style.

```bash
mvn spotless:apply
```

--------------------------------

### Configure Known Hosts File Strategy (YAML)

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/README.adoc

Configure the 'Known hosts file' SSH host key verification strategy using this YAML. This strategy relies on the existing `known_hosts` file on the Jenkins controller and agents.

```yaml
security:
  gitHostKeyVerificationConfiguration:
    sshHostKeyVerificationStrategy: "knownHostsFileVerificationStrategy"
```

--------------------------------

### Run JMH Benchmarks

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Execute Java Microbenchmark Harness (JMH) benchmarks to compare command line git and JGit performance. The '-Dbenchmark.run=true' flag is required.

```bash
mvn -P jmh-benchmark -Dbenchmark.run=true test
```

--------------------------------

### Approved Host Keys Format

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/src/main/resources/org/jenkinsci/plugins/gitclient/verifier/ManuallyProvidedKeyVerificationStrategy/help-approvedHostKeys.html

Specify allowed host keys in the format compatible with `known_hosts` file entries. Each line should contain a hostname followed by its public key.

```text
github.com ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOMqqnkVzrm0SdG6UOoqKLsabgH5C9okWi0dh2l9GKJl
bitbucket.org ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOMqqnkVzrm0SdG6UOoqKLsabgH5C9okWi0dh2l9GKJl
```

--------------------------------

### Run Spotbugs Analysis

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Analyze the project for potential bugs using Spotbugs. This command checks for new Spotbugs issues.

```bash
mvn spotbugs:check
```

--------------------------------

### Configure Manually Provided Keys Strategy (YAML)

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/README.adoc

This YAML configuration sets up the 'Manually provided keys' SSH host key verification strategy. It allows administrators to specify host keys directly for Git repository servers.

```yaml
security:
  gitHostKeyVerificationConfiguration:
    sshHostKeyVerificationStrategy:
      manuallyProvidedKeyVerificationStrategy:
        approvedHostKeys: |- 
          bitbucket.org ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIIazEu89wgQZ4bqs3d63QSMzYVa0MuJ2e2gKTKqu+UUO
          github.com ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOMqqnkVzrm0SdG6UOoqKLsabgH5C9okWi0dh2l9GKJl
          gitlab.com ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIAfuCHKVTjquxvt6CM6tdG4SLp1Btn/nOeHHE5UOzRdf
```

--------------------------------

### Run Plugin in Jenkins Environment

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Run the plugin locally within a Jenkins environment using the maven-hpi-plugin. Specify the Jetty port.

```bash
mvn -Djetty.port=8080 hpi:run
```

--------------------------------

### Generate Code Coverage Report

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/CONTRIBUTING.adoc

Generate a code coverage report using JaCoCo. This requires enabling the 'enable-jacoco' profile.

```bash
mvn -P enable-jacoco clean install jacoco:report
```

--------------------------------

### Configure No Verification Strategy (YAML)

Source: https://github.com/jenkinsci/git-client-plugin/blob/master/README.adoc

This YAML configuration disables SSH host key verification. It is not recommended due to security risks like 'man-in-the-middle' attacks.

```yaml
security:
  gitHostKeyVerificationConfiguration:
    sshHostKeyVerificationStrategy: "noVerificationStrategy"
```
