Question

当我尝试运行由sbt构建的jar时，会抛出

java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering。我反编译了那个jar，发现它缺少那个方法。

然而，在其他节点上，一切都很好。相同的项目和相同版本的sbt（0.13.8），不知道哪里出错了。

假设工作节点是A而功能失调的是B.我在两个节点上删除了jackson-core-2.1.1 jar，在sbt编译之后，节点A没有下载那个jar但是节点B没有。这真的很奇怪。

最终通过强迫sbt使用jackson-2.4.1来解决这个问题。

  , "com.fasterxml.jackson.core"       %   "jackson-core"             %   jacksonV force()
  , "com.fasterxml.jackson.core"       %   "jackson-annotations"      %   jacksonV force()
  , "com.fasterxml.jackson.core"       %   "jackson-databind"         %   jacksonV force()

我打印了整个项目的依赖树，发现没有对jackson 2.1.1的传递依赖，但不知何故sbt将它打包到fat-jar中。

在sbt建立的jar中缺少方法
