当我构建我的项目时，我得到了这个。我似乎无法下载任何 google 依赖项。

所有以 Maven 为目标的 Google 依赖项都失败了。不确定是什么问题。

我已尝试将 cacert 添加到我的 Java 证书中，但仍然无法获取。

很少检查以缩小问题范围

  1. 查看此证书安装指南以检查您执行的任何错误步骤。
  2. 仔细检查给出此异常的 jre 与您安装 ssl 根证书的完全相同

通过在命令提示符下键入以下命令进行检查并查看 java 主路径，并且只有您应该将证书添加到 cacerts。

mvn -version
  1. 确认它是您安装且未过期的根 SSL 证书。如果您安装已过期的非根证书，您可能会遇到问题。
