Sqoop2的代码结构相对于Sqoop做了大幅度调整，当中编译方式也从ant+maven杂糅的方式变为依赖maven3。今天将源码下下来，放到linux測试机器/export/build下后，执行“ mvn package -Pbinary -Dhadoop.profile=200 ”命令，竟然出现下面错误：

通过网上搜索发现，原来须要改动docs/模块下的pom.xml。将当中依赖的maven-site-plugin插件版本号进行替换。 本身的版本号已经过时了，替换为3.3的版本号就可以。
<plugin>
<artifactId>maven-site-plugin</artifactId>
<version>3.3</version>
</plugin>假设使用mvn clean install 编译时，还可可能碰到下面错误：

解决方法是改动总控pom.xml中jdk编译版本号与本机安装jdk版本号保持一致：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compile.source>1.7</maven.compile.source>
<maven.compile.target>1.7</maven.compile.target>
<commons-dbcp.version>1.4</commons-dbcp.version>
<commons-lang.version>2.5</commons-lang.version>
