Install ECS SDK for Java

This topic describes how to install Elastic Compute Service (ECS) SDK for Java and the Alibaba Cloud SDK core library.

1. Use one of the following methods to configure the Maven project management tool in IDEA:
   • Use the integrated Maven project management tool in IDEA.
   • Download the Maven software corresponding to the operating system from the official Maven website (Download Apache Maven) and manually configure the Maven tool.
2. Go to Alibaba Cloud SDKs to obtain the Alibaba Cloud SDK core library and Maven dependencies of ECS.
3. Create a Maven project by using one of the following methods:
   • Method 1: Create a Maven project in IDEA.
   • Method 2: Convert an existing project into a Maven project.
     1. Right-click the project to be converted and select Add Framework Support....
     2. Select Maven and click OK.
4. Add the aliyun-java-sdk-core, aliyun-java-sdk-ecs, and fastjson dependencies to the pom.xml file in the project directory.
   After the dependencies are added, the Maven project management tool automatically downloads the corresponding JAR packages.

   Note SDK packages are frequently updated. We recommend that you obtain the latest version of dependencies from the official Alibaba Cloud SDKs website.

   <dependencies>
       <dependency>
           <groupId>com.aliyun</groupId>
           <artifactId>aliyun-java-sdk-core</artifactId>
           <version>4.5.6</version>
       </dependency>
       <dependency>
           <groupId>com.aliyun</groupId>
           <artifactId>aliyun-java-sdk-ecs</artifactId>
           <version>4.19.9</version>

           <version>1.2.73</version>
       </dependency>
   </dependencies>

5. Check External Libraries in the project directory.
   If a command output similar to the one shown in the following figure is generated, the dependencies are imported.
