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

`` 1. 安装thrift0.13.0 版本(注意：Doris0.15 和最新的版本基于thrift0.13.0 构建, 之前的版本依然使用thrift` 0.9.3 构建)

  1. Windows:
    1. 下载：http://archive.apache.org/dist/thrift/0.13.0/thrift-0.13.0.exe
    1. 拷贝：将文件拷贝至 ./thirdparty/installed/bin

  4. MacOS:

    1. 下载：brew install thrift@0.13.0
    1. 建立软链接：
  7. mkdir -p ./thirdparty/installed/bin

  8. ln -s /opt/homebrew/Cellar/thrift@0.13.0/0.13.0/bin/thrift ./thirdparty/installed/bin/thrift

  9. 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
    1. brew extract --version='0.13.0' thrift $USER/local-tap
    1. brew install thrift@0.13.0
  13. 参考链接: https://gist.github.com/tonydeng/02e571f273d6cce4230dc8d5f394493c ```
  14. 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：

1. cd fe 2. mvn generate-sources

如果出现错误，则执行：

1. 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）

  1. 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
