从sbt:
运行TwitterServer时出现此错误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杰克逊的依赖从其他地方(circe)传递过来。我以为我可以用这种方式将它覆盖到2.6.7,但似乎没有效果:
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?
答案 0 :(得分:3)
看起来我也需要在这些覆盖上导入库依赖项,即使我没有直接使用它们:
libraryDependencies ++= Seq(
`jackson-databind`,
`jackson-core`,
`jackson-annotations`,
`jackson-datatype-jsr310`,
// ...
)
