At present, there are defects in the chapter on debugging FE in doc. My colleagues and I stepped on the pit when building the debugging environment, so I want to improve this chapter in combination with my own stepping on the pit experience. The following is my explanation of the changes: 1. mkdir -p ./thirdparty/installed/bin explain: When I downloaded versions 0.14 and 0.15, there were no files under thirdparty, so I didn't know whether to create it myself or what to do. Finally, I decided to create it myself. I think it's necessary to add instructions here. 2. Add installation thrift@0.13.0 Failed handling method. explain: My colleagues and I failed to find the installation package when executing the installation command, and finally found a solution on GitHub. Therefore, I added the handling method of the problem to avoid other Mac users from getting stuck in this place. 3. Fixed an error in the generated code description. explain: Before I finished building the code, I debugged FE, and I failed all the time. Idea hints that no files can be found. Later, after consulting with morningman in wechat group, it was understood that `mvn install -DskipTests` does not need to execute `mvn generate-sources` after execution. This is inconsistent with the description in the document and needs to be corrected.

# 使用 IntelliJ IDEA 搭建 FE 开发环境
|
|
|
|
## 1.环境准备
|
|
|
|
JDK1.8+, IntelliJ IDEA
|
|
|
|
1. 从 https://github.com/apache/incubator-doris.git 下载源码到本地
|
|
|
|
2. 使用IntelliJ IDEA 打开代码根目录
|
|
|
|
3. 如果仅进行fe开发而没有编译过thirdparty，则需要安装thrift，并将thrift 复制或者连接到 `thirdparty/installed/bin` 目录下
|
|
|
|
安装 `thrift` 0.13.0 版本(注意：`Doris` 0.15 和最新的版本基于 `thrift` 0.13.0 构建, 之前的版本依然使用`thrift` 0.9.3 构建)
|
|
|
|
Windows:
|
|
1. 下载：`http://archive.apache.org/dist/thrift/0.13.0/thrift-0.13.0.exe`
|
|
2. 拷贝：将文件拷贝至 `./thirdparty/installed/bin`
|
|
|
|
MacOS:
|
|
1. 下载：`brew install thrift@0.13.0`
|
|
2. 建立软链接：
|
|
`mkdir -p ./thirdparty/installed/bin`
|
|
`ln -s /opt/homebrew/Cellar/thrift@0.13.0/0.13.0/bin/thrift ./thirdparty/installed/bin/thrift`
|
|
|
|
注：MacOS执行 `brew install thrift@0.13.0` 可能会报找不到版本的错误，解决方法如下，在终端执行：
|
|
1. `brew tap-new $USER/local-tap`
|
|
2. `brew extract --version='0.13.0' thrift $USER/local-tap`
|
|
3. `brew install thrift@0.13.0`
|
|
参考链接: `https://gist.github.com/tonydeng/02e571f273d6cce4230dc8d5f394493c`
|
|
|
|
4. 如果是Mac 或者 Linux 环境 可以通过 如下命令生成自动生成代码：
|
|
|
|
```
|
|
cd fe
|
|
mvn generate-sources
|
|
```
|
|
|
|
如果出现错误，则执行：
|
|
|
|
```
|
|
cd fe && mvn clean install -DskipTests
|
|
```
|
|
|
|
或者通过图形界面运行 maven 命令生成
|
|
|
|
|
|
|
|
如果使用windows环境可能会有make命令和sh脚本无法执行的情况 可以通过拷贝linux上的 `fe/fe-core/target/generated-sources` 目录拷贝到相应的目录的方式实现，也可以通过docker 镜像挂载本地目录之后，在docker 内部生成自动生成代码，可以参照编译一节
|
|
|
|
## 2.调试
|
|
|
|
1. 用idea导入fe工程
|
|
|
|
2. 在fe目录下创建下面红框标出的目录（在新版本中该目录可能存在，如存在则跳过，否则创建）
|
|
|
|
|
|
|
|
3. 编译`ui`项目，将 `ui/dist/`目录中的文件拷贝到`webroot`中（如果你不需要看`Doris` UI，这一步可以跳过）
|
|
|
|
## 3.配置conf/fe.conf
|
|
|
|
下面是我自己的配置，你可以根据自己的需要进行修改
|
|

## 4.设置环境变量
|
|
|
|
在IDEA中设置运行环境变量
|
|
|
|
|
|
|
|
## 5.启动fe
|
|
|
|
下面你就可以愉快的启动，调试你的FE了
