在Eclipse IDE中使用maven / m2e从.proto自动生成Java [英] Automatically generate Java from .proto with maven/m2e in Eclipse IDE

问题描述

对于我的团队，我想配置maven / eclipse构建以从 *。proto 文件自动生成Java代码（在使用 gRPC ）。目前需要运行 mvn generate-source 或 mvn protobuf：compile （如插件使用页面）。或者什么是相同的添加运行配置来调用maven目标编译。

For my team, I'd like to configure maven/eclipse build to automatically generate Java code from *.proto files (in a project that uses gRPC). Currently one needs to run mvn generate-source or mvn protobuf:compile (as in plugin usage page). Or what is the same add Run configuration to invoke maven goal compile.

每当Eclipse Maven项目被刷新（< kbd> Alt + F5 ）或IDE重新启动，项目重建，但不会出现在 target / generated 中，因此转动项目变成红色。所以需要生成和刷新项目（ F5 ）。 UPDATE Eclipse需要在 .clathpath 文件中配置源文件夹。

Whenever Eclipse Maven project is refreshed (Alt+F5) or IDE is restarted, project is rebuilt but without what should appear in target/generated, thus turning project into red. So one need to generate and refresh project (F5). UPDATE Eclipse has needed source folders configured in .clathpath file.

我知道应该是m2e连接器，但是我只能找到一个 https://github.com/masterzen/m2e-protoc-connector对于最旧的Google 的插件com.google.protobuf.tools:maven-protoc-plugin ，甚至目前在 https://github.com/grpc/grpc-java

As I know that should be m2e connector, but I could only find one https://github.com/masterzen/m2e-protoc-connector for the oldest Googles plugin com.google.protobuf.tools:maven-protoc-plugin, that is even not mentioned currently at https://github.com/grpc/grpc-java

我们使用完全引用/推荐的

We use exactly referenced/recommended

  <groupId>org.xolstice.maven.plugins</groupId>
  <artifactId>protobuf-maven-plugin</artifactId>

即：

<build>
  <extensions>
    <extension>
      <groupId>kr.motd.maven</groupId>
      <artifactId>os-maven-plugin</artifactId>
      <version>1.4.1.Final</version>

  </extensions>
  <plugins>
    <plugin>

      <configuration>
        <protocArtifact>com.google.protobuf:protoc:3.1.0:exe:${os.detected.classifier}</protocArtifact>
        <pluginId>grpc-java</pluginId>
        <pluginArtifact>io.grpc:protoc-gen-grpc-java:1.0.1:exe:${os.detected.classifier}</pluginArtifact>
      </configuration>

          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

相关：

• 链接到Eclipse中生成的Java protobuf代码


• 看着这个，但该作者正在使用其他较旧的，现在不支持插件：由protobuf生成的代码（与Maven Project Builder相关）导致的Eclipse构建循环
  
  PPS该插件< a href =https://github.com/igor-petruk/protobuf-maven-plugin =nofollow noreferrer> https://github.com/igor-petruk/protobuf-maven-plugin 但是，如 https://github.com/os72/protoc-jar-maven-插件

• Linking to generated Java protobuf code in Eclipse
• looked at this but that author was using other older, not supported now plugin : Eclipse build loop caused by protobuf generated code (related to Maven Project Builder)
  P.P.S That plugin https://github.com/igor-petruk/protobuf-maven-plugin however has continuation as https://github.com/os72/protoc-jar-maven-plugin

推荐答案

for protobuf-行家-插件

for protobuf-maven-plugin

感谢sergei-ivanov在 https://github.com/xolstice/protobuf-maven-plugin/issues/16 ，它给了链接 https://github.com/trustin/os-maven-plugin#issues-with- eclipse-m2e-or-other-ides ：

Thanks to sergei-ivanov answer in https://github.com/xolstice/protobuf-maven-plugin/issues/16, that gave link https://github.com/trustin/os-maven-plugin#issues-with-eclipse-m2e-or-other-ides :

需要下载os-maven-plugin-xxxFinal.jar（您的pomx中的版本） .ml），并将其放入< ECLIPSE_HOME> / plugins 目录中。

One need to download os-maven-plugin-x.x.x.Final.jar (the version as in your pomx.ml) and put it into the <ECLIPSE_HOME>/plugins directory.

之后Eclipse将生成源包括在Maven-update项目之后...（ Alt + F5 ），但不是在Project - > Build（或默认自动构建）后。还有在IDE开始它不会编译。

After that Eclipse will generate source on project clean, including after Maven -update project... (Alt+F5), but not after Project -> Build (or with default Build Automatically). Also on IDE start it will not compile.

是的，这是不合逻辑的：

Yes, that is illogical:

清理将生成和编译Java源

但是

项目 - Build不会。
