为什么 sbt 找不到这些杰克逊依赖项
Why is sbt failing to find these jackson dependency
我正在尝试添加依赖项以支持 java.time jackson 库。这些依赖项是：
val jacksonVersion = "2.9.7"
libraryDependencies += "com.fasterxml.jackson.module" % "jackson-module-parameter-names" % jacksonVersion
libraryDependencies += "com.fasterxml.jackson.module" % "jackson-datatype-jdk8" % jacksonVersion
libraryDependencies += "com.fasterxml.jackson.module" % "jackson-datatype-jsr310" % jacksonVersion
如指定的那样here
问题是 sbt 找不到它们。基于 Maven 网页 here，它们应该在 Maven Central 和 JCenter 可用，所以我将解析器添加到我的依赖项中：
resolvers += Resolver.JCenterRepository
resolvers += Resolver.DefaultMavenRepository
我知道一个应该足够了，但它们似乎不起作用。他们解析的网址是：

但显然他们不在那里。我不知道我错过了什么...
这是 jackson-datatype-jdk8 的错误。

知道为什么没有依赖关系吗？
根据您提供的 link，您的最后 2 个依赖项应该是 datatype :
val jacksonVersion = "2.9.7"
libraryDependencies += "com.fasterxml.jackson.module" % "jackson-module-
parameter-names" % jacksonVersion
libraryDependencies += "com.fasterxml.jackson.datatype" % "jackson-datatype-jdk8"
% jacksonVersion
libraryDependencies += "com.fasterxml.jackson.datatype" % "jackson-datatype-jsr310" % jacksonVersion
顺便说一句，已经有更新的版本 - 2.9.8 - 看看 here
