升级SBT错误

Question

我试图将Scala应用程序升级到2.8，这涉及到将SBT升级到1.x。

在我的build.propeties里我有sbt.version=1.3.5

在plugins.sbt中

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.7.4")

然而，我看到以下几点：

这是我的解决方案：

resolvers += Resolver.typesafeRepo("releases")
resolvers += Resolver.typesafeIvyRepo("releases")
resolvers += Resolver.sbtPluginRepo("releases")
resolvers += Resolver.url("heroku-sbt-plugin-releases", url("http://dl.bintray.com/heroku/sbt-plugins/"))(Resolver.ivyStylePatterns)
resolvers += Resolver.bintrayRepo("neomaclin", "maven")

是什么导致了关于使用https的所有这些警告？更重要的是，当我查找那些ivy.xml文件时，我得到404 s，但显然控制台中有那些PKIX错误。当我不是代理的时候，我为什么要得到这些？我想我使用了错误的坐标，但我不知道它们是怎么错的。

Answer 1

对我起作用的是将我的JDK升级到11，因为那个版本的Java在它的信任存储中拥有发出SBT想要发出的请求所必需的证书。

Answer 2

为了避免这些错误，请确保您对所需访问的存储库具有权限。此外，确保sbt凭据文件包含用于访问这些存储库的凭据。有多种方法可以通过IntelliJ preferences > build, Execution, Deployments > sbt或~/.sbt/.credentials设置这种设置。
