Setup

1. Build the Plugin

mvn clean package

This creates target/dev-commands-plugin-1.0.0.jar

2. Install on Server

Copy the JAR to your Paper server's plugins/ directory:

cp target/dev-commands-plugin-1.0.0.jar /path/to/server/plugins/

3. Configure

Edit plugins/DevCommandsPlugin/config.yml:

GitHub Configuration

github:
  token: "${GITHUB_TOKEN}"  # Or hardcode your token (not recommended)
  repository: "cedricclyburn/minecraft-for-standup"
  api-url: "https://api.github.com"

Getting a GitHub Token:

1. Go to GitHub Settings > Developer Settings > Personal Access Tokens
2. Generate new token (classic)
3. Select scopes: repo (for private repos) or just public_repo
4. Set as environment variable: export GITHUB_TOKEN=ghp_xxxxx

Jira Configuration

jira:
  url: "${JIRA_URL}"  # Your Jira instance (e.g., https://yourcompany.atlassian.net)
  email: "${JIRA_EMAIL}"  # Your Jira email
  api-token: "${JIRA_API_TOKEN}"  # Generate at https://id.atlassian.com/manage-profile/security/api-tokens
  project-key: "PROJ"  # Your default project key

Getting a Jira API Token:

1. Go to https://id.atlassian.com/manage-profile/security/api-tokens
2. Click "Create API token"
3. Give it a label (e.g., "Minecraft Plugin")
4. Copy the token and set as environment variable: export JIRA_API_TOKEN=your_token_here

GitHub Projects Configuration

Uses the same GitHub token as PR reviews. Just set the default project number:

github:
  project-number: 1  # Your default project board number

AI/MaaS Configuration

Configure the AI endpoint (MaaS or self-hosted vLLM):

vllm:
  url: "http://maas.apps.ocp.cloud.rhai-tmm.dev/kimi-k25/kimi-k2-5"  # MaaS endpoint (no /v1 suffix)
  model: "kimi-k2-5"  # Model name
  api-token: "${MAAS_TOKEN}"  # Bearer token from environment variable
  max-tokens: 2048
  temperature: 0.7
  timeout: 60  # Kimi k2.5 can handle longer requests

Note: The client automatically appends /v1/chat/completions to the URL.

4. Set Environment Variables (Recommended)

In your Minecraft server startup script or OpenShift deployment:

export GITHUB_TOKEN=ghp_your_token_here
java -jar paper.jar

Or in OpenShift, create a secret:

oc create secret generic github-token --from-literal=GITHUB_TOKEN=ghp_xxxxx

Then mount it in your Minecraft server deployment.

Troubleshooting

"Failed to fetch PR"

• Check your GitHub token is valid and has correct permissions
• Verify the repository name is correct (owner/repo format)
• Ensure the PR number exists

"vLLM request failed"

• Check vLLM service is running: oc get pods
• Verify the service URL is correct
• Check vLLM logs: oc logs deployment/vllm

Books not appearing

• Check inventory is not full
• Look in server logs for errors
• Verify permissions

"Please wait X seconds"

• Cooldown between commands (configurable)
• Prevents API spam

Requirements

• Paper/Spigot 1.20.4+ (or compatible version)
