If you use Apache Maven to manage Java projects, you only need to add corresponding dependencies to the pom.xml files of the projects. You can download the Maven dependencies of different cloud products in Alibaba Cloud developer resources.

You must install aliyun-java-sdk-core library no matter which product development kit you want to use. For example, to call the ECS SDK, you need to install aliyun-java-sdk-core library and aliyun-java-sdk-ecs library.

To use the Ecs SDK as an example, you only need to declare the following two dependencies in the pom.xml file:

<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-core</artifactId>
    <version>[4.3.2,5.0.0)</version>
</dependency>
<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-ecs</artifactId>
    <version>[4.16.0,5.0.0)</version>
</dependency>

If maven is not downloading jar packages from a central repository, you need to add this dependency in the pom.xml file, or a NoClassDefFoundError exception will be reported

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.5</version>
</dependency>
