编译期间未捕获的异常：java.lang.AssertionError

时间：2015-04-15 17:58:16

标签： scala sbt jodatime

这是我学习scala的第二天，所以我无法自信地说，但它看起来像编译器错误，不是吗？

我的项目中有一个代码文件：

import org.joda.time.DateTime
import org.joda.time.DateTimeZone

object CheckCompilation {
  val time = new DateTime(DateTimeZone.forID("Europe/Minsk"))
}

build.sbt：

name := "ScalaCompilerCheck"

version := "1.0"

libraryDependencies += "joda-time" % "joda-time" % "2.7"

`sbt compile`输出：

fromString取决于joda-convert。将其添加到您的build.sbt文件中：

libraryDependencies ++= Seq(
  "joda-time" % "joda-time" % "2.7",
  "org.joda" % "joda-convert" % "1.7"
)
