无法创建PlayFramework@2.7.x应用

我做了

sbt新建playframework/play scala seed.g8

，出现了一些错误

我在官方网站上看到了这个命令。

这个错误似乎与PlayFramework和sbt无关。因此，我添加了一个标签

sbt

有人帮我吗

以下是将typesafe.com证书添加到JRE cacerts的更多详细信息：

• 从以下位置下载InstallCert：
• javac InstallCert.java
• java InstallCert typesafe.com
• keytool-exportcert-alias typesafe.com-1-keystore jssecacerts-storepass changeit-file typesafe.com.cer
• keytool-importcert-alias typesafe.com-keystore\u JRE\u目录\lib\security\cacerts-storepass changeit-file typesafe.com.cer

您应该将_JRE_目录更改为实际值。然后用“是”回答这个问题：

信任这个证书吗？[否]：是

我解决了这个问题。问题是缺少typesafe.com的证书。
