protoc自定义插件错误，提示“程序未找到或不可执行" [英] protoc custom plugin erroring out with Program not found or is not executable

问题描述

我正在尝试构建自定义协议插件，以从.proto文件生成自定义输出.我从协议自定义插件中复制了包含CodeGenerator的java文件作为起点，并重命名了.我还遵循了可执行文件并创建了.sh文件.我的shell脚本的内容如下.

I am trying to build a custom protoc plugin to generate custom output from .proto files. I literally copied java file containing CodeGenerator from protoc custom plugin as a starting point and renamed it. I also followed executable and created .sh file. The content of my shell script is as follows.

我还添加了PATH变量值和插件执行的输出.有人可以指出我的错误之处吗? shell脚本可以单独执行main方法正常运行

I also add the PATH variable value and output of the plugin execution. Can someone point me where I am going wrong with this? The shell script runs fine separately executing the main method

推荐答案

如果这是您的整个example.sh，它将不起作用，因为它没有用于标识脚本解释器的"hashbang"行.

If that is your entire example.sh, it won't work because it doesn't have a "hashbang" line identifying the script interpreter.

应该是这样的:

#!/bin/bash
set -e
java cp ...

我认为这很可能是您的问题，因为我尝试运行protoc并以与您指定的方式相同的方式指定了一个插件，并且只要该插件实际上是自己可执行的，它就可以工作.

I think that's likely your problem because I tried running protoc and specifying an plug-in in the same way you did, and it worked as long as the plug-in was actually executable on its own.
