protoc-jar-maven-plugin：不生成grpc服务存根

Question

我已经添加了如下Maven配置。

        <plugin>

              <groupId>com.github.os72</groupId>

              <artifactId>protoc-jar-maven-plugin</artifactId>

              <version>3.5.1</version>

              <executions>

                  <execution>

                      <phase>generate-sources</phase>

                      <goals>

                          <goal>run</goal>

                      </goals>

                      <configuration>

                          <protocArtifact>com.google.protobuf:protoc:3.0.0</protocArtifact>

                          <inputDirectories>

                              <include>src/main/protobuf</include>

                          </inputDirectories>

                         <outputTargets>

                              <outputTarget>

                                  <type>java</type>

                                  <outputDirectory>src/main/java</outputDirectory>

                              </outputTarget>

                              <outputTarget>

                                  <type>grpc-java</type>

                                  <outputDirectory>src/main/java</outputDirectory>

                                  <pluginArtifact>io.grpc:protoc-gen-grpc-java:1.0.1</pluginArtifact>

                              </outputTarget>

                          </outputTargets>

                      </configuration>

                  </execution>

              </executions>

       </plugin>

我通过“ mvn protoc-jar：run”执行它，但是它跳过了grpc服务存根，只将“消息”隐蔽到Java代码中。

我只输出生成为HelloReply，HelloReplyOrBuilder，HelloRequest，HelloRequestOrBuilder，HelloWorldProto的文件。缺少Greeter Grpc服务存根。我是Maven的新手，我错过了什么。
