central has elapsed or updates are forced. Original error: Could not transfer artifact com.fasterxml.jackson.core:jackson-

- Missing artifact com.fasterxml.jackson.core:jackson-databind:jar:2.9.0.pr3

其实已经说的很清楚了。

因为那个 2.9.pr3.jar 已经缓存在了本地，所以下载（transfer ）失败。只有过了指定的时间间隔，或强制更新，才会去重新解析。

—— resolution will not be reattempted until the update interval of
central has elapsed or updates are forced

那么，把 jackson-databind-2.9.0.pr3.jar.lastUpdated 删除后， maven 就会去重新下载。

修改 pom，（增加了一空行），还是不行。。。

手动将jackson-databind-2.9.0.pr3.jar 下载到本地，放到 mvn 仓库中，再次修改 pom， ok了！
