准备工作，检查编译依赖程序版本，具体版本信息如下
- Maven, version 3+
- Java JDK 1.8
- Eclipse Release 4.7.0 (Oxygen)
- 下载 settings.xml 到你的 .m2 目录，请先备份原文件
正式开始：
一、从GitHub下载Kettle最新源码
下载地址：https://github.com/pentaho/pentaho-kettle/tree/8.0
二、导入项目
导入项目之前请确保setting.xml已经放到.m2目录中，用Eclipse通过Maven方式导入刚下载的Kettle项目。
三、安装依赖
项目有些jar包需要手动安装到本地maven库中，具体操作如下，所需 jar 包下载请 点击：

[INFO] ------------------------------------------------------------------------ 编译成功。pentaho-kettle-8.0\assemblies\pdi-ce\target目录会多一个pentaho-kettle-8.0.zip的压缩包，解压开就可以用喽。
当然编译成功只是编译的第一步，能够debug对于程序人员来说才是最终的目的。打开eclipse,kettle-ui-swt这个项目，为该项目添加swt的jar,同时还要把ui复制到\pentaho-kettle-8.0\ui\ui（这里的ui就是启动kettle看到的页面）中过来，不然等会运行会报错。
五、运行程序
1、从生成的最终文件运行
进入工作空间中的 pentaho-kettle-master\assemblies\pdi-ce\target 目录，找到 pdi-ce-8.0-SNAPSHOT.zip 文件，解压后运行 Spoon.bat 启动应用。
2、从Eclipse中运行
运行 kettle-ui-swt 项目的 org.pentaho.di.ui.spoon.Spoon 类。
运行结果：
六、问题汇总
1.Q:Plugin execution not covered by lifecycle configuration error in eclipse with pluginManagement in parent pom？
A:so go to Eclipse: Preferences -> Maven -> Error/Warnings and change Error to Warning in option: Plugin execution not converted by lifecycle configuration.
