sbt 子项目 testOnly ( scalatest ) 不工作

Question

我遇到的问题是我无法使用 testOnly 为特定模块运行一项测试..

lazy val root = (project in file("."))
  .settings(Commons.settings: _*)
  .aggregate(utils, `some-service`, otherService)

如果在 sbt 我这样做：project some-service 然后testOnly *MyTest 我收到一个错误：

[error] Expected ID character
[error] Not a valid command: testOnly
[error] Expected project ID
[error] Expected configuration
[error] Expected ':' (if selecting a configuration)
[error] Expected key
[error] Expected '::'
[error] Expected end of input.

运行所有测试都很好，但不仅仅是特定的。 有人知道怎么做吗？ 谢谢！

好的，我找到了原因。

testOnly in Test := (testOnly in Test).dependsOn(startDynamoDBLocal).value

应该改为：

testOnly in Test := (testOnly in Test).dependsOn(startDynamoDBLocal).evaluated
