The intention of thisunsafeNullsis to give users a better migration path for explicit nulls. Projects for Scala 2 or regular Scala 3 can try this by adding-Yexplicit-nulls -language:unsafeNullsto the compile options. A small number of manual modifications are expected. To migrate to the full...
后者用于加载和执行Scala编译器和Scaladoc工具,应该只包含scala-compiler库及其依赖项。 除非显式配置了任务的scalaClasspath,否则Scala(基本)插件将尝试从任务的classpath推断出它。推断过程如下: 如果在classpath上找到scala-library jar包,并且项目至少声明了一个存储库,则将相应的scala-compiler存储库依赖项添加到scala...
若使用Scala 3，应添加scala3-library_3依赖项。在ScalaClasspath的自动配置上，ScalaCompile和ScalaDoc任务在两种情况下使用Scala代码：在classpath上定位源代码引用的类，通常包含scala-library以及其他库；在scalaClasspath上加载和执行Scala编译器和Scaladoc工具，仅包含scala-compiler库及其依赖项。配置Zinc...
The Scala 3 compiler, also known as Dotty. Mill 9.2 9.9 Scapegoat VS Mill Mill is a fast JVM build tool that supports Java, Scala, Kotlin and many other languages. 2-4x faster than Gradle and 4-10x faster than Maven for common workflows, Mill aims to make your project’s build ...
The compiler knows that the elements of seq3 are of type Option[Int], which could include None elements. At runtime, a MatchError will be thrown if a None is encountered. The fix is straightforward: // src/script/scala/progscala3/patternmatching/MatchExhaustiveFix.scala scala> val result3...
2. Scala 2 syntax can be replaced with Scala 3(Scala 2 语法可被替换为 Scala 3) 只有启用编译器选项-Xsource:3时,这个检查才有效。 它会报告可被替换为 Scala 3 的 Scala 2 语法。 如果为兼容性使用-Xsource:3,但不需要重写代码,则可以将其安全禁用。
