背景
昨天下载的Kettle源码需要JDK11,今天按照官方发布的9.2版本重新下载源码地址为9.2.0.0-R/290对应JDK1.8,至于源码下载及编译可参照PDI/Kettle-9.4.0.0-343源码下载及编译步骤都是一样的。如果确实使用到JDK11,可以选择9.2之后的版本
目的
研究代码尝试二开PS:下载完代码编译了一下结果全是错详见问题记录
总体方向
把kettle任务编排提取出来做成web界面PS:编译项目干了一天
第二章 代码结构初识
基本结构 代码模块详情
integration测试代码模块据说很多已过时用处不大。 kettle-core:PDI的核心库包含了所有基本的数据处理功能。 该模块提供了数据源连接、数据流设计、转换步骤定义、元数据管理等功能。该模块不依赖于任何特定的UI框架或数据库驱动程序因此可以被其他应用程序以编程方式使用。 kettle-dbdialog:对话框 该模块包含了一个用于与用户交互的对话框用于配置数据库连接参数。该模块允许用户输入数据库URL、用户名、密码和其他必要的信息。 kettle-engine:核心引擎执行作业 该模块负责执行作业和转换。该模块包含了所有的核心逻辑包括错误处理、日志记录、插件管理和线程调度等。 kettle-ui-swt:图形用户界面 该模块为Kettle提供了一套基于SWTStandard Widget Toolkit的图形用户界面。用户可以通过这个GUI来创建、编辑和运行作业和转换。 pdi-assemblies: 该模块包含了PDI的所有组件的组装和打包脚本。该模块通过这些脚本可以将各个模块组合成一个完整的可部署的应用程序。 pdi-engine-ext:扩展 该模块包含了对引擎的扩展。这些扩展可能包括新的数据源连接器、新的步骤类型或者自定义的行为。 pdi-plugins:插件 该模块包含了各种插件它们扩展了PDI的功能。插件可以是预定义的步骤、输入/输出插件、自定义函数库等。
⁉️问题记录
❓问题一代码分支哪些是发布版本
❗答后缀-R的版本
在软件开发中-R和-RC通常代表不同的版本状态
-R这个后缀可能表示“Release”即正式发布的版本。这通常是软件经过多次测试和优化后的稳定版本可供广大用户下载和使用。-RC这个后缀通常表示“Release Candidate”即候选发布版本。这是软件发布周期中的一个阶段在这个阶段软件已经基本完成开发并且通过了内部的测试但还没有正式发布。RC版本通常用来收集最后阶段的反馈和错误报告以便在最终发布之前进行修复。
本文的版本9.2.0.0-290对应的就是9.2.0.0-R
