如何找到导致Scalac编译器崩溃的源文件

 夜晨在行动 发布于 2022-12-07 12:15
  • 编译
  • 文件
  • 搜索
  • java
  • int
  • io

    • 我正在将大型项目升级到2.10.4到2.11.4.我有一个编译器崩溃,无论如何显示导致崩溃的源文件的名称？我能够通过'last everitt/compile:compile'获得完整的跟踪

    我将恢复擦除项目的大块以二进制搜索崩溃的原因.

    这是跟踪btw:

    编辑:删除并评论出大量文件后,我将其简化为:

    case class A(x: String)
case class B(a: A, y: String)
class C(var b: B) {
  def a = b.a
  b.copy(a = a.copy())
}

    编辑2:我能说的最好的是,没有一个好的选择,我将继续前进,我提交了一个关于这个问题的错误报告(SI-9035).如果有人知道选项/方式,请发表答案!与此同时,我将继续使用自2.6以来一直使用的方法:擦除文件并注释掉行,直到我将其归结为最小示例并提交错误报告.谢谢你的想法.
