Protocol buffers compiler maven plugin
提问by Rajat Gupta
I have protocol buffers compiler plugin configured in my POM that is executed whenever the project is built. This complier plugin works fine in windows but now I moved my project to an ubuntu PC & need to used a suitable alterntive for this.
我在 POM 中配置了协议缓冲区编译器插件，每当项目构建时都会执行该插件。这个编译器插件在 Windows 中运行良好，但现在我将我的项目移到了 ubuntu PC 上，并且需要为此使用合适的替代方案。

<execution>
<id>compile-protoc</id>
<phase>generate-sources</phase>
<configuration>
<tasks>
<mkdir dir="src/main/resources/protocolBuffers/compiled" />

I see the following output when trying to build the project in Ubuntu netbeans

Your protoc executable could not be executed on linux. You should download and compile protoc for linux and once you do it you will be able to use this maven plug-in as you are using it on windows.
您的 protoc 可执行文件无法在 linux 上执行。你应该下载并编译 protoc for linux，一旦你这样做了，你就可以像在 Windows 上一样使用这个 maven 插件。
You have detailed instruction for this here

You still need protoc but I think it is nicer to use a a protobuf maven plugin to compile proto files
您仍然需要 protoc，但我认为使用 protobuf maven 插件来编译 proto 文件更好

This one comes with protoc built-in (it's originally based on igor-petruk/protobuf-maven-plugin, but it comes with protoc binaries bundled for Linux, Mac/OSX, and Windows). At runtime it detects the platform and executes the corresponding binary
这个内置了 protoc（它最初基于 igor-petruk/protobuf-maven-plugin，但它附带了为 Linux、Mac/OSX 和 Windows 捆绑的 protoc 二进制文件）。在运行时它检测平台并执行相应的二进制文件

Here's an example:

A good cross-platform solution is to use the protoc binary artifacts available in Maven Central.
一个好的跨平台解决方案是使用 Maven Central 中可用的 protoc 二进制工件。
The simple configuration changes needed to your pom.xml are described in the com.google.protobuf.tools: maven-protoc-plugin documentation "Resolving Protoc Artifact From Maven Central Repo"
com.google.protobuf.tools: maven-protoc-plugin 文档“Resolving Protoc Artifact From Maven Central Repo”中描述了 pom.xml 所需的简单配置更改
