Maven jar插件-Intellij jar文件中的java.lang.NoClassDefFoundError
我正在尝试从Maven项目中提取一个类,但找不到类错误。
我已将此添加到pom文件
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>training.avro.KafkaAvroJavaProducerV1Demo</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
我先进行maven安装,然后运行
java -jar target/kafka-avro-v1-1.0-SNAPSHOT.jar
这是我的项目的名称,当我从intellij运行时,该主类运行良好。
但是然后我从罐子中得到了这个错误
