克隆并建立Pentaho水壶 [英] Clone and Build Pentaho Kettle
问题描述
对不起，我提出了一个基本问题，但我已经尝试了一段时间，对此一无所获. 有没有人有经验克隆Pentaho-kettle项目并将其导入Eclipse? 我按照 https://github.com/pentaho/pentaho-kettle 中的说明进行操作. 我做了以下
Sorry for basic question, but I have been trying for a while and cannot get anywhere with this. Any one have experience clone the Pentaho-kettle project and import it into eclipse? I follow the instruction from https://github.com/pentaho/pentaho-kettle. I did the following
cd pentaho-kettle
ant clean-all resolve create-dot-classpath
然后我进入eclipse并将现有项目导入到工作区中.请注意，我是从根文件夹导入的.我是否应该包括扫描嵌套项目的选项? 即便如此，我也进入了几乎所有模块(核心，引擎，用户界面...)以运行相同的ant任务.但是，我在eclipse中仍然有很多错误. 一些错误是:找不到类型java.lang.Object(这确实很奇怪)，还有很多其他无法解析. 我还需要执行其他步骤吗?如果您已成功从仓库中克隆并构建成功，请在这里为我提供帮助.
Then I go into eclipse and Import Existing Project into workspace. Note that I am importing from the root folder. Should I include the option scan the nested projects? Even that, I went into almost all the module(core, engine, ui...) to run the same ant task. However, I still have a bunch of error within eclipse. Some errors are : Cannot find Type java.lang.Object (which is really strange), and a bunch other not resolving. Is there any other step I need to follow. If you have success cloning and building from the repo, please help me out here.
要更新，请按照以下说明进行操作:

如何构建Pentahos水壶
How to build Pentahos Kettle
下面是简单的说明.
必备工具
-
eclipse http://www.eclipse.org
首先，执行以获取最新的母版
First, execute to get latest master
git checkout https://github.com/pentaho/pentaho-kettle.git
然后执行(以获得所需的稳定版本)
then execute (to get stable release u need)
git checkout -b production origin/production
其中 production 是名称之一(红色突出显示)
where production is one of names can be found (highlighted red)
您实际上已经可以将该项目导入eclipse(文件->导入).如果您将分配给eclipse至少2GB RAM，这会更好(这是一个很大的项目).在$ ECLIPSE_HOME/eclipse.ini文件中进行一些更改:
u actually already may import this project into eclipse (File->Import). Better if u will assign to eclipse at least 2GB RAM (it is pretty big project). Make some changes in $ECLIPSE_HOME/eclipse.ini file:
-Xms2048m
-Xmx2048m
现在，导入完成后，eclipse看起来会这样
Now after import is done, eclipse will look this way
突出显示:
- 红色(导入pentaho-kettle项目后的默认项目)
- blue是我签出的项目(也考虑版本)，并在构建路径中添加到pentaho-kettle项目中(尽管某些类丢失了，尽管根据常春藤它们必须位于类路径中)
- 绿色错误是日食中的错误.甚至在我成功构建/运行/执行水壶DI之后留下的那些东西.另一个错误是不好的.
打开控制台(假设您的机器上已经有ant蚂蚁，并且您的PATH中已经有ant命令)
Open console (I assume ant already available on u machine and ant command already in your PATH)
cd pentaho-kettle
进入每个项目(突出显示的红色，除了 pentaho-kettle 项目)目录并执行
enter to each projects (highlighted red, except pentaho-kettle project) directories and execute
ant clean-all resolve create-dot-classpath
刷新eclipse中的项目.
refresh projects in eclipse.
注意:不要在pentaho-kettle目录命令中执行
Note: do not execute in pentaho-kettle directory command
ant clean-all resolve create-dot-classpath
它将清除子项目中的所有库，并且您必须从头开始.
It will erase all libraries in subprojects and u will have to start from beginning.
您完成了.现在，在Eclipse中启动/调试水壶(运行配置 pentaho-kettle 中的项目可用)
You are done. Now start/debug kettle in eclipse (item in Run Configuration pentaho-kettle will be available)
图像上的某些项目以蓝色突出显示，它们用在pentaho-kettle中(我想它们应该被预先编译为pentaho-kettle/lib中的jar文件，但是ivy脚本没有下载它们，也没有将它们添加到pentaho-kettle项目的类路径.Eclipse将报告缺少一些一些".我只是从github中手动将它们检出为单独的项目(尊重版本)，并将它们添加到构建路径中的pentaho-kettle项目选项
Some of projects on image highlighted blue, they are used in pentaho-kettle (I think they suppose to be precompiled as jar files in pentaho-kettle/lib but ivy script didn't download them and didn't add them to pentaho-kettle project classpath. Eclipse will report "Some of classes are missing". I just checked them out from github manually as separate project (respect version) and add them to pentaho-kettle project in build path options
就这样.
