maven-shade:pom:3.2.4在之前的尝试错误中未能从http://repo.maven.apache.org/maven2传输

Question

我引进了一个由某人开发的项目。

然而，当我导入项目时，我一直在pom.xml中得到这个错误：

在前一次尝试中，org.apache.maven.plugins:maven-shade-plugin:pom:3.2.4

未能从https://repo.maven.apache.org/maven2传输。此故障被缓存在本地存储库中，在中央更新间隔已经过去或更新被强制执行之前，解析不会重试。原始错误:无法传输伪影org.apache.maven.plugin.

我怎样才能解决这个问题？

这是项目的pom.xml

我尝试过智能导入，并手动导入，并不断获得相同的错误。

您使用的版本不是最新版本(3.4.1)，<configuration>标记应该在<executions>标记之外。

请看一下关于如何配置maven-阴影插件的官方文档：https://maven.apache.org/plugins/maven-shade-plugin/usage.html。
