我是Maven的新手,并且一直在寻找教程和网络,以获取有关如何从模式文件.avsc构建.avro的文档。基于apache.maven.org网站上的文档。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>
我已将其添加到我的POM.xml文件中。我有2个模式文件(.avsc),以下是我的目录结构,内容为
我的POM.xml是

我执行了以下
mvn clean generate-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,我发现问题完全出现在我的.avsc JSON问题上。 “名称空间”完全错了。我一修好了。 maven avro插件从架构中创建了java类。

首先不是JSON问题。由于在pom.xml中添加了标签而发生了问题
要注意的点:
i.e标签用于管理子模块中的插件。
因此无需在pom.xml中添加标签。
