通过 SBT 下载插件时如何修复 SSL 错误？

Question

我有一个相当小的示例SBT 项目。

特别是，这是我的project/plugins.sbt ：

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.9")

这是我的project/build.properties ：

sbt.version = 1.2.8

加载我的项目时我在 SBT 中遇到的错误是这样开始的：

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

这是我安装的JVM版本：

$ /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

虽然，当我运行sbt console （从没有 SBT 项目的目录）时，我得到：

Welcome to Scala version 2.10.6 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_31).
Type in expressions to have them evaluated.
Type :help for more information.

我有 macOS Mojave 10.14.5。

我假设我需要更新我的证书存储。 我该怎么做？

或者我应该做些什么来解决这个问题？

Answer 1

通过执行 sbt 控制台仔细检查 sbt 使用的 java 版本。 它应该说类似于Welcome to Scala 2.12.7 (OpenJDK 64-Bit Server VM, Java 1.8.0_202) 。 就我个人而言，我建议清理当前安装并尝试像这样采用openjdk8

brew cask install adoptopenjdk8
