导入 SBT 项目时出错答案

【问题标题】：Error while importing SBT project导入 SBT 项目时出错
【发布时间】：2018-04-20 04:52:31
【问题描述】：

下面是我在构建 SBT 项目时看到的日志。下面想说什么！

我正在使用 IntelliJ IDE 和 Scala 2.12 和 SBT 1.0.3 来构建项目。我已经验证了 IDE 代理设置，它的设置并且适用于其他构建工具。是否缺少我的 SBT 安装？我尝试访问日志中的失败链接，但它们也出现错误。

更新 SBT

name := "untitled3"

版本 := "0.1"

scalaVersion := "2.12.4"

excludeDependencies += "org.apache.logging.log4j"

【问题讨论】：

嗨，你怎么能解决这个问题？谢谢。

标签： scala intellij-idea sbt

【解决方案1】：

就我而言，这与任何代理无关。我在 project/build.properties 中指定了 sbt.version=1.0.3，并且我安装了 sbt 版本 1.1.1。失败模式令人费解。

【讨论】：

【解决方案2】：

对我来说，这是在升级 scala 2.12.11 -> 2.13.2 时发生的。原来我正在使用当时不支持 scala 2.13 的库。我的 build.sbt 看起来像这样（简化）：

scalaVersion := "2.12.11"

libraryDependencies += "org.apache.spark" %% "spark-core" % "2.4.0"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.0"
libraryDependencies += "org.apache.spark" %% "spark-mllib" % "2.4.0"

当使用 double percent 时，工件名称会获得一个带有 scala 主要和次要版本的后缀，例如 spark-core 被转换为 spark-core_2.12。当我将 scalaVersion 更改为 2.13.2 时，我将依赖带有 _2.13 后缀的依赖项，它不存在（我检查了 maven central，2.12 是支持的最新 scala。

【讨论】：

这对我有用。在我的情况下，依赖问题是由不支持 2.13 的插件引起的。
@mjuanes 很高兴听到这个消息，考虑支持答案

【解决方案3】：

在过去的几天里，似乎 SBT 的发布缓存中已经消失了一些 0.13.x 和 1.x.x 的 SBT 所需的东西。仍在寻找答案，我在 Maven 2 中为此添加了一个解析器，它应该可以找到这个东西（它是来自 Maven 2 的 DOWNLOADABLE ...），但它忽略了这个东西

我很快就被 sbt 深深打动了，就像我对 Autotools 一样（这是一件非常非常糟糕的事情......）。无论如何，工具都应该尽可能复杂，并且在使用时要适度直接。它们应该是自给自足的，而不是像 sbt 似乎习惯做的那样，随意地从以太中拉出一堆东西。

我会自己进一步挖掘，看看能否以某种方式解决它并相应地更新答案。

【解决方案4】：

在我的例子中，启动 sbt 服务器影响了重新加载一个 sbt 项目。关闭服务器帮了我

【解决方案5】：

在 sbt 设置中将堆大小增加到 5GB 解决了我的问题
