安裝 - - 阿里雲

本文介紹阿里雲Java SDK推薦的Maven安裝方式。具體包含2個步驟，首先需要在pom.xml設定檔中添加阿里雲Java SDK的Maven倉庫，然後再添加ApsaraVideo for Media Processing的依賴。

添加maven倉庫。

<repositories>
       <repository>
           <id>sonatype-nexus-staging</id>
           <name>Sonatype Nexus Staging</name>
           <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
           <releases>
               <enabled>true</enabled>
           </releases>
           <snapshots>
               <enabled>true</enabled>
           </snapshots>
       </repository>
   </repositories>

添加依賴。
阿里雲Java SDK核心庫以及ApsaraVideo for Media ProcessingJava SDK的詳細版本：
- 阿里雲Java SDK核心庫版本
- ApsaraVideo for Media ProcessingJava SDK版本
以3.5.0版本SDK的核心庫和2.5.2版本的ApsaraVideo for Media ProcessingSDK為例：
```
<dependency>
         <groupId>com.aliyun</groupId>
         <artifactId>aliyun-java-sdk-core</artifactId>
         <version>3.5.0</version>
   </dependency>
   <dependency>
         <groupId>com.aliyun</groupId>
         <artifactId>aliyun-java-sdk-mts</artifactId>
         <version>2.5.2</version>
   </dependency>
```
另外有一個可選的json庫依賴。在ApsaraVideo for Media Processing的API中，很多參數都是json定義，java的json庫有很多，可以選擇熟悉的庫，以1.2.46版本的 fastjson 為例：
```
<dependency>
       <groupId>com.alibaba</groupId>
       <artifactId>fastjson</artifactId>
       <version>1.2.46</version>
   </dependency>
```
