datax源代码编译安装

what is DataX ？

DataX是阿里巴巴集团内被广泛使用的离线数据同步工具/平台。
实现包括MySQL，SQL Server，Oracle，PostgreSQL，HDFS，Hive，HBase，OTS，ODPS等各种异构数据源之间高效的数据同步功能。

1.从Github下载源码，地址：https://github.com/alibaba/DataX?spm=a2c4e.11153940.blogcont642896.16.7d62ba62hHwiVO&file=DataX.git；

 DataX-master.zip

2.安装好maven，通过maven打包源码编译：

 mvn -U clean package assembly:assembly -Dmaven.test.skip=true

3.编译好的datax在 /target/datax/下：

{YOUR_DATAX_HOME}/target/datax/

4.编译过程中出现的报错解决办法：

4.1.maven配置阿里云的maven私服

<mirror> 
    <id>nexus-aliyun</id> 
    <mirrorOf>central</mirrorOf>
    <name>Nexus aliyun</name> 
    <url>https://maven.aliyun.com/repository/central</url> 
</mirror>

4.2.本地编译报错无法找到工件com.aliyun.openservices：tablestore-streamclient：jar：1.0.0-SNAPSHOT;

vim otsstreamreader/pom.xml

 <dependency>
   <groupId>com.aliyun.openservices</groupId> 
   <artifactId>tablestore-streamclient</artifactId> 
   <version>1.0.0-SNAPSHOT</version>
 </dependency>

 此处把
    <version>1.0.0-SNAPSHOT</version>
改成
    <version>1.0.0</version>

4.3.编译datax odps插件模块会报错：

ERROR] Failed to execute goal on project odpsreader: Could not resolve dependencies for project com.alibaba.datax:odpsreader:jar:0.0.1-SNAPSHOT:

 [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:
 [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/DependencyResolutionException 

比较过之前odps-sdk-core-0.19.3-public.pom的的依赖是
org.bouncycastle bcprov-jdk15on 1.52
现在是
com.alibaba.external bouncycastle.provider 1.38-jdk15

原因：  后来的这个依赖应该是阿里内部jar，外部仓库无法加载这个jar

   解决：修改pom.xml

com.aliyun.odps
odps-sdk-core
换一下版本 ：0.20.7-public 

5.编译成功：

6.测试：在eclipse中建立EngineTest.java,使用默认的job.json:
