以编程方式编译 Scala 文件时检测到竞态条件

Question

我正在尝试按如下方式运行 Scala 编译器：

val settings = new Settings
settings.usejavacp.value = true
settings.embeddedDefaults[LmsCompiler]
val compilerOptions = "-d" :: jarPath :: config.extraCompilerOptions.toList
settings.processArguments(compilerOptions, false)
val reporter = new StoreReporter
val compiler: Global = new Global(settings, reporter)
val run = new compiler.Run
run.compile(List(srcFile))

（请参阅 object scala in compiler mirror not found - running Scala compiler programatically 了解 extendedDefaults）。但是，我遇到了类似的测试失败

[info] - logicalOps *** FAILED ***

即使我没有使用任何并发。我该如何解决这个错误？

Answer 1

问题是使用了错误的Global 类；我必须导入 scala.tools.nsc.Global 而不是 scala.tools.nsc.interactive.Global。
