在Kotlin中使用哪个标准库 [英] Which standard library to use in Kotlin

问题描述

在Kotlin中，使用JVM时，标准库似乎有多种选择，分别是kotlin-stdlib，kotlin-stdlib-jdk7和kotlin-stdlib-jdk8.

In Kotlin, when working with the JVM, it seems there is multiple choices for standard library, namely kotlin-stdlib, kotlin-stdlib-jdk7 and kotlin-stdlib-jdk8.

但是，我找不到任何能告诉我两者之间差异的信息. 我发现的唯一可见区别是我不能将com.fasterxml.jackson.databind.exc.MismatchedInputException与kotlin-stdlib一起使用，但是可以与kotlin-stdlib-jdk8一起使用.

I cannot, however, find anything telling me the difference between these. The only visible difference I have found is that I cannot use com.fasterxml.jackson.databind.exc.MismatchedInputException with kotlin-stdlib, but I can with kotlin-stdlib-jdk8.

在任何地方我都可以使用一个优势来了解其优势，或者有人可以通俗易懂地解释这一优势?

Is there anywhere I can read about the advantages using one over the others, or can anyone explain this in layman terms?

推荐答案

顾名思义，在使用JDK8时应使用-jdk8.它包含用于将JDK 8中所做的更改集成到Kotlin标准库中的代码.

As the name indicates, -jdk8 is supposed to be used when using the JDK8. It contains code used to integrate the changes made in the JDK 8 into the Kotlin standard lib.

如pom所示，它依赖于-jdk7，该代码包含将JDK 7中所做的更改集成到Kotlin标准库中所需的代码.

As its pom indicates, it depends on -jdk7, which contains the code needed to integrate the changes made in the JDK 7 into the Kotlin standard lib.

-jdk7的pom表示，它取决于stdlib.

And as the pom of -jdk7 indicates, it depends on the stdlib.

因此，简而言之，请使用与您的JDK匹配的一个.将其添加到依赖项中还将通过传递方式添加JDK早期版本中的所有依赖项.

So, in short, use the one matching your JDK. Adding it to the dependencies will also, transitively, add all the ones for the previous versions of the JDK.
