# 使用 VSCode 搭建 FE 开发环境
|
|
|
|
有些开发者是在 开发机/WSL/docker 上搭建 FE 开发环境，但是这样的开发环境不能支持本地开发，有些习惯于使用 VSCode 的开发者可以配置远程开发调试
|
|
|
|
## 环境准备
|
|
|
|
* JDK11+ (Java 插件需要 JDK11+) (笔者是在 `home` 目录下建立了一个 lib 目录，分别安装了 [JDK11](https://github.com/adoptium/temurin11-binaries/releases/) 和 JDK8 ，分别用于插件和编译)
|
|
* VSCode
|
|
+ Extension Pack for Java 插件
|
|
+ Remote 插件
|
|
|
|
## 下载代码编译
|
|
|
|
1. 从 https://github.com/apache/doris.git 下载源码到本地
|
|
|
|
2. 使用 VSCode 打开代码 `/fe` 目录
|
|
|
|
## 配置 VSCode
|
|
|
|
在 `.vscode` 目录下创建 `settings.json` 文件, 分别配置
|
|
|
|
* `"java.configuration.runtimes"`
|
|
* `"java.jdt.ls.java.home"` -- 必须另外配置，指向 JDK11+ 的目录，用于配置 vscode-java 插件
|
|
* `"maven.executable.path"` -- 指向 maven 的目录，用于配置 maven-language-server 插件
|
|
|
|
example:
|
|
|
|
```json
|
|
{
|
|
"java.configuration.runtimes": [
|
|
{
|
|
"name": "JavaSE-1.8",
|
|
"path": "/!!!path!!!/jdk-1.8.0_191"
|
|
},
|
|
{
|
|
"name": "JavaSE-11",
|
|
"path": "/!!!path!!!/jdk-11.0.14.1+1",
|
|
"default": true
|
|
},
|
|
],
|
|
"java.jdt.ls.java.home": "/!!!path!!!/jdk-11.0.14.1+1",
|
|
"maven.executable.path": "/!!!path!!!/maven/bin/mvn"
|
|
}
|
|
```
|
|
|
|
## 编译
|
|
|
|
其他文章已经介绍的比较清楚了：
|
|
* [使用 LDB toolchain 编译](/docs/install/source-install/compilation-with-ldb-toolchain)
|
|
* ......
|
|
|
|
为了进行调试，需要在 fe 启动时，加上调试的参数，比如
|
|
|
|
```bash
|
|
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
|
|
```
|
|
|
|
具体是在 `doris/output/fe/bin/start_fe.sh` 里 `$JAVA $final_java_opt` 后面加上上面的参数。
