Eclipse查看flume源码
首先电脑要安装Maven
本文使用的是：apache-maven-3.0.5-bin.tar.gz
解压，配置环境变量。
Maven安装好后检查，出现下面信息表示安装Maven成功。

下载源码：
apache-flume-1.5.0-src.tar.gz
开始编译：
E:\software\apache-flume-1.5.0-src>mvn install -DskipTests
出现的问题：
解决办法：
进入apache-flume-1.5.0-src\flume-ng-sinks\flume-ng-morphline-solr-sink\目录下pom.xml文件：
将<
然后加上：

解决办法：
修改apache-flume-1.5.0-src目录下的pom.xml文件，将其中
如果还有错误的话，修改apache-flume-1.5.0-src\flume-ng-sinks\flume-ng-morphline-solr-sink\目录下pom.xml文件：
