加特林斯卡拉地图

Question

我正在将加特林从1.5.6版本升级到2.3.1 这样做我也有2.10.4

下面的代码给出了编译错误：

Map("somedata1" -> somedata1,
  "somedata2" -> somedata3,
  "somedata3" -> somedata3
)

错误

Reference to method -> in class ArrowAssoc should not have survived past type checking,
[ERROR] it should have been processed and eliminated during expansion of an enclosing macro.
[ERROR]       Map("somedata1" -> somedata1,
