无法使用 Maven 从 .avsc 编译和创建 .avro 文件

我是 Maven 新手，一直在查看教程和网络以获取有关如何从架构文件 .avsc 构建 .avro 的文档。基于 apache.maven.org 站点上的文档。我必须添加以下内容

<dependency>
  <groupId>org.apache.avro</groupId>
  <artifactId>avro</artifactId>
  <version>1.7.5</version>
</dependency>

<plugin>
  <groupId>org.apache.avro</groupId>
  <artifactId>avro-maven-plugin</artifactId>
  <version>1.7.5</version>
  <executions>
    <execution>
      <phase>generate-sources</phase>
      <goals>
        <goal>schema</goal>
      </goals>
      <configuration>
        <sourceDirectory>${project.basedir}/src/main/avro/</sourceDirectory>
        <outputDirectory>${project.basedir}/src/main/java/</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.6</source>
    <target>1.6</target>
  </configuration>
</plugin>

我已将相同的内容添加到我的 POM.xml 文件中。我有 2 个架构文件 (.avsc)，以下是我的目录结构及其内容

• ProjectDir
  • src
    • main
      • java
      • avrò
        • abc.avsc
      • 资源
  • test
• pom.xml

我的 POM.xml 是

            </configuration>
        </plugin>
    </plugins>
  </pluginManagement>   
  </build>
 </project>

我执行了以下操作

mvn clean generated-sources 我得到以下输出

感谢这方面的任何帮助。谢谢

经过大量研究后，我发现问题完全出在我的 .avsc JSON 问题上。 “命名空间”是完全错误的。我一修好。 maven avro 插件从模式创建了 java 类。
