问题描述

Debug shows (in line loop(null, this, this) of List.scala: 调试显示List.scala（在loop(null, this, this) ：

在此处输入图片说明

and the line parents mapConserve this of TypeMaps.scala: 和parents mapConserve this行parents mapConserve this TypeTypes.scala：

在此处输入图片说明

How can I check what line is causing it? 我如何检查是哪条线引起的？

SBT compile takes 361 s and it throws: SBT编译需要361秒，并且抛出：

You should be able to use remote debugging. 您应该能够使用远程调试。 Create a remote debugger configuration in your favorite IDE ( http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Fconcepts%2Fcremdbug.htm for Eclipse, https://www.jetbrains.com/help/idea/2016.2/run-debug-configuration-remote.html for IDEA) containing scala-compiler-<your-scala-version>-sources.jar and scala-reflect-<your-scala-version>-sources.jar . 在您喜欢的IDE中创建一个远程调试器配置（ http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Fconcepts%2Fcremdbug.htm for Eclipse， https：/ /www.jetbrains.com/help/idea/2016.2/run-debug-configuration-remote.html（适用于IDEA），其中包含scala-compiler-<your-scala-version>-sources.jar和scala-reflect-<your-scala-version>-sources.jar scala-compiler-<your-scala-version>-sources.jar scala-reflect-<your-scala-version>-sources.jar 。 Add 加 

set javaOptions in compiler := List("-Xdebug", "-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8002")

(taken from https://groups.google.com/d/msg/scala-user/XI_Ujax_Oq8/o2Hrs-KjAgAJ ) in your SBT build. （摘自https://groups.google.com/d/msg/scala-user/XI_Ujax_Oq8/o2Hrs-KjAgAJ ）在您的SBT版本中。 Then when you run sbt compile it'll wait until you start a debugging session. 然后，当您运行sbt compile它将等待直到启动调试会话。 Set an exception breakpoint for StackOverflowError and you should localize the problem (not necessarily to a specific line). 为StackOverflowError设置一个异常断点，您应该将问题本地化（不一定要到特定的行）。
