java - 为什么 hamcrest 在我的类(class)路径中？

Question

我已经将 gradle 与 intellij 集成在一起，我似乎无法弄清楚为什么 hamcrest 库在我的类路径中，即使它没有在 build.gradle 中列出。

Answer 1

因为 junit:junit:4.12 将其作为传递依赖引入。你可以通过运行看到这一点

./gradlew dependencies

这是 jUnit 文档中的相关部分

There is nothing extra that needs to be done in order to use a specific artifact of Hamcrest. In the past, there were two JUnit Maven artifacts: junit:junit and junit:junit-dep, where the latter version did not include a bundled copy of org.hamcrest:hamcrest-core and instead declared a transitive dependency on Hamcrest. In order to be more Maven-like, starting in version 4.11, there is only the junit:junit artifact which uses a transitive dependency on hamcrest-core.
