一、项目依赖导入：
用的是本地的maven3.3.9，setting.xml文件如下：
C:\Users\ZH\Work\apache-maven-3.3.9\repository
central
Maven Repository Switchboard
https://repo1.maven.org/maven2/

小技巧
如果卡在某个文件的下载，实在自动下载不下来的，可以手动下载放到相应的目录下，并把该目录下的_remote.repositories文件删除，这样idea会优先读取本地仓库的文件；删除maven库中的.lastUpdated文件，然后update maven project，循环往复直到直到仓库中没有.lastUpdated文件，项目所有依赖导入完毕。
二、异常处理
依赖全部成功下载后，启动运行遇到以下几个异常：
1.java.lang.UnsatisfiedLinkError: Could not load SWT library.
java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-gtk-4623 in java.library.path

at org.pentaho.di.ui.spoon.Spoon.main(Spoon.java:668)
原因：
swt相关依赖默认为linux环境，需要修改为win环境，笔者的机器为win11 64位 专业版
解决方案：
打开kettle-ui-swt的pom.xml文件，注释掉org.eclipse.swt.gtk.linux.x86_64的依赖，并在dependencys的开头，添加org.eclipse.swt.win32.win32.x86_64的依赖
org.eclipse.swt
org.eclipse.swt.win32.win32.x86_64

原因：
源码中Spoon的方法registerUIPluginObjectTypes()中会注册环境根目录下的plugins目录，后续扫描插件jar包时会用到。
如：BasePluginType类的方法registerPluginJars()与findAnnotatedClassFiles( String x)，会对plugins下的jar文件扫描。
而编译后的项目会在target目录下存在插件jar包，但是并没有在plugins目录下存在正确的插件目录如日志插件目录kettle5-log4j-plugin、json插件目录kettle-json-plugin
所以在扫描到这些jar包后初始化时找不到对应目录下的某些文件导致出错。
解决方案：
启动失败后， IDEA 会自动添加一个启动配置，点击工具栏上的启动配置【Spoon】然后点击【Edit Configurations】
配置Spoon的启动configuration，设置Working directory项为kettle-ui-swt项目的目录，其下没有plugins目录自然扫描不到jar包，不会执行日志插件初始化操作。
这样启动的kettle是没有插件的，如果想加载插件则需要将编译后的zip包的plugins和system目录拷贝至kettle-ui-swt根目录下

原因：
静态xul文件未找到
解决方案：
找到根项目的assemblies目录下的子项目pdi-static的resources下的ui下的所有xul文件，复制至kettle-ui-swt项目相同位置

原因：

解决方案：
找到kettle-engine项目下的pom.xml，找到如下依赖，注释掉test域可见的配置，使其将依赖传递至kettle-ui-swt，reload一下
