尝试编译play模板项目时未解析的依赖项: sbt-plugin;2.7.0

Question

按照play网站"sbt new playframework/play-scala-seed.g8“的指导创建了一个新的play模板项目

尝试编译/运行该项目时，我得到了以下结果：

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

我的Scala版本是2.12.4，而且我确实安装了SBT1.0，所以我有点搞不懂为什么会发生这种情况。有什么想法吗？

如果您遵循此处的响应，然后使用repo.scala-sbt.org代替google.com部分

如下所示：

echo -n | openssl s_client -connect repo.scala-sbt.org:443 | sed -ne‘/-开始证书-/，/-结束证书-/p’> /tmp/scala.cer

按照链接中的其余说明进行操作，它应该可以工作。
