不兼容的 Jackson 版本:sbt 中的 2.7.1?

Incompatible Jackson version: 2.7.1 in sbt?

当 运行 来自 sbt 的 TwitterServer 时我收到此错误:

SEVERE: LoadService: failed to 
instantiate 'com.twitter.finagle.stats.MetricsExporter' 
for the requested service 'com.twitter.finagle.http.HttpMuxHandler'
com.fasterxml.jackson.databind.JsonMappingException: 
Incompatible Jackson version: 2.7.1

2.7 Jackson 依赖项正在从其他地方 (circ) 传递过来。我以为我可以通过这种方式覆盖它到2.6.7,但它似乎没有效果:

val jacksonV = "2.6.7"
val `jackson-core` = "com.fasterxml.jackson.core" % "jackson-core" % jacksonV
val `jackson-databind` = "com.fasterxml.jackson.core" % "jackson-databind" % jacksonV
val `jackson-annotations` = "com.fasterxml.jackson.core" % "jackson-annotations" % jacksonV
val `jackson-datatype-jsr310` = "com.fasterxml.jackson.datatype" % "jackson-datatype-jsr310" % jacksonV
dependencyOverrides += `jackson-core`
dependencyOverrides += `jackson-databind`
dependencyOverrides += `jackson-annotations`
dependencyOverrides += `jackson-datatype-jsr310`

知道为什么这不会覆盖任何东西吗?

看来我也需要导入这些覆盖的库依赖项,即使我没有直接使用它们也是如此:

libraryDependencies ++= Seq(
    `jackson-databind`,
    `jackson-core`,
    `jackson-annotations`,
    `jackson-datatype-jsr310`,
    // ...
)
