Maven的antrun-插件：生成的protobuf不會生成Java文件來源

我在pom.xml以下插件，它應該產生其他項目的編制要求的java文件：Maven的antrun-插件：生成的protobuf不會生成Java文件來源

         <arg value="proto/U.proto" />

        </exec> 
       </tasks> 
       <sourceRoot>src-gen</sourceRoot> 
      </configuration> 
      <goals> 
       <goal>run</goal> 
      </goals> 
     </execution> 
    </executions> 
</plugin>

然而，這根本不會在src-gen文件夾下產生任何東西。然後我不斷收到錯誤，如：

cannot find symbol 
[ERROR] symbol: class AMsg 
[ERROR] location: class project.messages.AFormatter

和

package project.messages.ros.RosHeader does not exist 
package project.messages.ros.RosPoint does not exist 
package project.messages.ros.RosPose does not exist 
package project.messages.ros.RosPoseStamped does not

基本上無法找到所需文件，自然，並給出錯誤。我已經安裝了2.5.0版本，並且依賴性被正確定義：

<dependency> 
    <groupId>com.google.protobuf</groupId> 
    <artifactId>protobuf-java</artifactId> 
    <version>2.5.0</version> 
</dependency>

我已經用完了想法。什麼使這不起作用？

編輯：下了我的注意的mvn install -X調試輸出：

你是說'maven-antrun-plugin'根本不被調用？或者它被調用，但'protoc'沒有被調用或者沒有生成文件？你能用'-X'運行時發佈與'maven-antrun-plugin'相關的日誌嗎？ – Tunaki

它被調用，我可以看到'[exec]在調試輸出中用參數：[exec]'--java_out = src-gen''和這些行執行'protoc'。讓我分享這個問題下的相關內容。編輯：只需添加調試輸出。 –

你可以用'--java_out = $ {basedir}/src-gen'來嘗試（即指定一個絕對路徑）嗎？ – Tunaki

當約沒有得到創建的文件疑問，請確保您使用絕對路徑。在這種情況下，${basedir}允許我們去Maven的基本目錄的位置的絕對路徑（POM的位置）：

<mkdir dir="${basedir}/src-gen" /> 
<exec executable="protoc"> 
    <arg value="--java_out=${basedir}/src-gen" /> 
    <arg value="--proto_path=${basedir}" /> <!-- proto_path needs to point to where the proto files are --> 
    <arg value="proto/ros/RosTime.proto" /> 
    <!-- rest of proto files... --> 
</exec>

然後，注意maven-antrun-plugin的<sourceRoot>參數被棄用：

Deprecated. Use the build-helper-maven-plugin to bind source directories

建議您使用build-helper-maven-plugin:add-source目標將源文件夾添加到您的Maven項目中。使用該目標的sources參數配置要添加的文件夾。

說了這麼多，你可能會使用org.xolstice.maven.plugins:protobuf-maven-plugin，而不是依靠Ant任務有更好的機會：

Maven Protocol Buffers Plugin uses Protocol Buffer Compiler (protoc) tool to generate Java source files from .proto (protocol buffer definition) files for the specified project.

的compile目標可以用於生成Java源文件。將.proto文件放在src/main/proto（可配置protoSourceRoot參數）下，插件將生成${project.build.directory}/generated-sources/protobuf/java（可用outputDirectory參數配置）中的Java源文件。

如果protoc可執行文件不在PATH環境變量中，可以使用protocExecutable參數進行設置。
