将协议缓冲区集成到Maven2构建中

您可以在Protocol Buffers存储库中找到有关该插件的一些信息 Protocol Buffers Compiler Maven Plug-In Protocol Buffers讨论组上的主题。我的理解是,它是可用的,但缺乏测试。我会试试的。

或者你可以直接使用 antrun 插件(从上面提到的线程粘贴的狙击):

 <build>
   <plugins>
     <plugin>
       <artifactId>maven-antrun-plugin</artifactId>
       <executions>
         <execution>
           <id>generate-sources</id>
           <phase>generate-sources</phase>
           <configuration>
             <tasks>
               <mkdir dir="target/generated-sources"/>
               <exec executable="protoc">
                 <arg value="--java_out=target/generated-sources"/>
                 <arg value="src/main/protobuf/test.proto"/>
               </exec>
             </tasks>
             <sourceRoot>target/generated-sources</sourceRoot>
           </configuration>
           <goals>
             <goal>run</goal>
           </goals>
         </execution>
       </executions>
     </plugin>
   </plugins>
 </build>

 <dependencies>
   <dependency>

   </dependency>
 </dependencies>

accepted answer 鼓励我使用谷歌提供的插件。我将问题中提到的分支合并到2.2.0源代码的签出中,构建并安装/部署了插件,并能够在我的项目中使用它,如下所示:

protobuf-maven-plugin

我刚刚更新了maven插件,使其与2.2.0兼容——更新后的pom附加到了代码审查bug中。

以下是自己构建插件的说明:

svn co http://protobuf.googlecode.com/svn/branches/maven-plugin/tools/maven-plugin
cd maven-plugin
wget -O pom.xml 'http://protobuf.googlecode.com/issues/attachment?aid=8860476605163151855&name=pom.xml'
mvn install

我刚刚尝试了一个不太官方但很新的(v 0.1.7)fork https://github.com/dtrott/maven-protoc-plugin

<temporaryProtoFileDirectory>${basedir}/target/temp</temporaryProtoFileDirectory>

紧接着

<protocExecutable>protoc</protocExecutable> .

https://www.xolstice.org/protobuf-maven-plugin/usage.html

最小配置

 <plugin>
    <groupId>org.xolstice.maven.plugins</groupId>
    <artifactId>protobuf-maven-plugin</artifactId>
    <version>0.5.0</version>
    <configuration>
      <protocExecutable>/usr/local/bin/protoc</protocExecutable>
    </configuration>
    <executions>
      <execution>
        <goals>
          <goal>compile</goal>
          <goal>test-compile</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

antrun

maven-exec-plugin .
