idea编译grpc-java的教训

梦里梦外; 2022-12-14 13:31 333阅读 0赞

## 准备工作 ##

首先要保证电脑环境（手机恐怕不行）安装了基本的jdk（8+），idea（任意版本），maven（3.6.3），gradle（6.5），git（2.27.0）等。如果没有请先百度安装配置，磨刀不误砍柴工。

## 接下来的工作 ##

尽可能按照官网说明来搞，[官方文档][Link 1] 。不要自己直接`git clone https://github.com/grpc/grpc-java` down到本地之后就开始干上了。

愚蠢的我就是直接git clone ，错误步骤如下：

> $ git clone https://github.com/grpc/grpc-java  
> $ cd grpc-java/examples  
> $ ./gradlew installDist

结果一直报错 ：

D:\Work\Learn\java\grpc-java\examples>gradlew installDist
    > Task :extractIncludeProto FAILED
    
    FAILURE: Build failed with an exception.
    
    * What went wrong:
    Execution failed for task ':extractIncludeProto'.
    > Could not resolve all files for configuration ':compileProtoPath'.
       > Could not find io.grpc:grpc-protobuf:1.34.0-SNAPSHOT.

让我产生了是不是是国内无法连接国外的远程仓库，鼓捣了很久。最后才想到git clone 拉的时master版本，而真正release 的版本是 v1.32.1 ,然后在idea中切换一下tag（直接命令行切换tag也可），命令才执行成功。

如果一开始就按照[官方文档][Link 1]来搞,就不会有问题了。算是一个教训，写下来提醒自己。
