🚀 Quick Start

Prerequisites

• MuleSoft Anypoint Studio 7.18+ or Anypoint Platform access
• MuleSoft Runtime 4.9.0+ (supports latest features and performance improvements)
• Oracle Fusion Cloud instance (ERP/EPM) with API access
• Java 17+ (LTS version recommended)
• Maven 3.9+ (for build and dependency management)

Installation

1. Clone the repository

   git clone https://github.com/msaleme/oracle-fusion-mulesoft-best-practices.git
   cd oracle-fusion-mulesoft-best-practices

2. Import into Anypoint Studio

   • File → Import → Anypoint Studio → Anypoint Studio project from File System
   • Select the project directory
   • Click Finish

3. Configure credentials

   # src/main/resources/config/dev.yaml
   oracle:
     fusion:
       baseUrl: "https://your-instance.oraclecloud.com"
   
   auth:
     clientId: "your-client-id"
     clientSecret: "${secure::clientSecret}"

4. Run the application

   mvn clean install
   mvn mule:run
