根据错误消息：
Transfer failed for https://repo.maven.apache.org/maven2...unable to find valid certification path to requested target它显示Maven正在尝试从位于https://repo.maven.apache.org/maven2的Maven中央存储库下载一个间接依赖项，这是一个安全HTTP服务器(HTTPS)。因此，问题可能来自您的证书本身或您的网络。
对于证书，尝试https://repo.maven.apache.org/maven2并下载证书，然后使用命令将其添加到仙人掌中：
keytool -import -alias example -keystore .\cacerts -file example.cer请尝试查看此线程"PKIX path building failed" and "unable to find valid certification path to requested target"的更多信息。
对于网络，请尝试访问您浏览器上的那个URL，并检查它是否可操作。如果您真的不能从浏览器中使用HTTPS访问Maven Central Repo，那么可能是因为您支持某种代理规则，从而阻止您下载服务器证书。
您可以设置settings.xml文件如下所示：
<proxies>
<proxy>
<active>true</active>
<protocol>https</protocol>
<host>MY_COMPANY_HOST</host>
<port>8080</port>
<username>MY_USERNAME</username>
<password>MY_PASSWORD</password>
<nonProxyHosts>localhost</nonProxyHosts>
