我有一个可通过 HTTPS 访问的 Nexus。只有授权用户有权访问它。使用 Maven，当所有必需的工件都在本地存储库中时，我什至可以部署构建工件。但是当我从本地存储库中删除一些必需的工件时，构建失败。

当我使用 wget 从这个 Nexus 下载工件时，我必须添加 --no-check-certificate 密钥来跳过服务器的证书（因为它是自签名的），然后我可以使用 wget 下载它。
我犯了 Java 密钥 -Dsun.security.ssl.allowUnsafeRenegotiation=true，但它根本没有改变任何东西。
之后我发现这可能不是自签名证书问题，因为我使用命令将服务器的证书添加到受信任列表中：
keytool -keystore $JAVA_HOME/jre/lib/security/cacerts -import -file certificate.cer
有人知道如何在构建时从 Nexus 下载工件吗？
