# Multi-Project Debugger

## Project Execution Guide

This skill helps debug the following projects simultaneously:
- FlinkDataSync
- com.lianda.auth (Authentication Service)
- JavaBackEnd (Main Backend Service)
- vue-frontend (Frontend Application)

## Accurate Execution Commands

### 1. JavaBackend
**Location:** `d:\Project\LiandaTugboat\Code\JavaBackend`
**Command:** `mvn spring-boot:run`
**Port:** 8080
**Purpose:** Main backend service with business logic

### 2. vue-frontend
**Location:** `d:\Project\LiandaTugboat\Code\vue-frontend`
**Command:** `npm run serve`
**Port:** 8082
**Purpose:** Frontend user interface

### 3. com.lianda.auth
**Location:** `d:\Project\LiandaTugboat\Code\com.lianda.auth`
**Command:** `mvn spring-boot:run`
**Port:** 8083
**Context Path:** `/auth`
**Purpose:** Authentication and authorization service

### 4. FlinkDataSync
**Location:** `d:\Project\LiandaTugboat\Code\FlinkDataSync`
**Build Command:** `mvn clean package -DskipTests`
**Run Command:** `java -cp target/flink-data-sync-1.0-SNAPSHOT.jar com.lianda.flink.sync.MySqlCdcSync`
**Purpose:** Real-time data synchronization between databases using Flink CDC

## When to Use
Invoke this skill when the user asks to debug multiple projects, troubleshoot integration issues, or needs to understand how these systems work together.

## Project Overview
1. **FlinkDataSync**: Handles data synchronization processes using Apache Flink and CDC technology
2. **com.lianda.auth**: Authentication and authorization service running on port 8083 with context path /auth
3. **JavaBackEnd**: Main business logic and API layer running on port 8080
4. **vue-frontend**: User interface layer that communicates with backend services

## Troubleshooting Tips
- If FlinkDataSync fails to start, ensure the build completes successfully first
- Check that all database connections are properly configured
- Verify that ports 8080, 8082, and 8083 are available
- For FlinkDataSync, ensure proper database credentials are configured in the application
- Monitor logs across all services to track inter-service communication
