我试图使用以下插件构建一个grpc服务。似乎插件无法使用protoc实用程序。
操作系统: MAC
Maven版本: 3.6.3
错误:
[ERROR] PROTOC FAILED: google/protobuf/wrappers.proto: File not found.
order-mgmt.proto: Import "google/protobuf/wrappers.proto" was not found or had errors.
order-mgmt.proto:7:16: "google.protobuf.StringValue" is not defined.
...
**[ERROR] Failed to execute goal org.xolstice.maven.plugins:protobuf-maven-plugin:0.6.1:compile (default) on project OrderManagement-gRPC: protoc did not exit cleanly. Review output for more information. -> [Help 1]**我使用的插件是:

您缺少了protobuf-java依赖项。
<dependencies>
<dependency>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java</artifactId>
<version>3.5.1-1</version>
</dependency>
...
</dependencies>下面是我如何使用插件。
<build>
<extensions>
<extension>
<groupId>kr.motd.maven</groupId>
<artifactId>os-maven-plugin</artifactId>
<version>1.5.0.Final</version>
</extension>
</extensions>
<plugins>
<plugin>
<groupId>org.xolstice.maven.plugins</groupId>
<artifactId>protobuf-maven-plugin</artifactId>
<version>0.5.1</version>
<extensions>true</extensions>
<configuration>
<protocArtifact>com.google.protobuf:protoc:3.5.1-1:exe:${os.detected.classifier}</protocArtifact>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>然后使用mvn protobuf:compile生成存根。参考资料来自https://github.com/xolstice/protobuf-maven-plugin的插件回购
