同学你好，1、根据报错信息，表示在pom文件的第8行出现问题，例如：

请问同学的plugin标签的外层是否有plugins标签呢？比如：

2、如果还报错，建议同学贴一下最新的pom文件，以及具体的报错信息。老师来检查测试一下。

如果我的回答解决了你的疑惑，请采纳，祝：学习愉快~

同学你好，同学刷新后还是不能正确打包吗。

如果还是不能打包，还有一种可能就是由于eclipse的版本不同，导致打包的插件无法加载的问题，同学可以尝试把之前plugin的内容注释掉，换成下面的内容试一下。

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>com.cyc.pinyintest.PinYinTest</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>

查看同学jdk与maven版本，并没有什么问题。

同学你好,Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4 --》这个打包失败的问题，建议重新刷新加载项目看能不能一起解决，鼠标右键工程，选择maven→update project 。

如果还是不行，建议同学说一下你的JDK和Maven的版本。

重新打包成功后，再来试试，另外打包成功的标识：

当出现BUILD FAILURE或者error表示打包失败。

刷新过了 jdk1.8.0_181 apache-maven-3.6.3 是因为兼容问题嘛

2020-04-20 15:04:46
乌卡卡uka 回复提问者慕姐6114392 #2

你的jdk是8_181，最好换成maven3.5.4版本的，3.6.3版本的maven会导致一些jar包无法完整下载。我之前也报过这种错误
