SQL Server地理结果格式(SQL Server geography result format)

 “聚合”是使test在其他项目（称为聚合项目或“执行依赖项”）以及当前项目上执行的功能的名称。 您可以在“ 多项目构建”页面上找到更多信息。 
 
 我会在“主”项目中创建一个自定义任务，该任务取决于您要运行的任务。 例如， 
 
myTestTask <<= Seq(
  test in (main, Test),
  test in (abc, Test),
  test in (deff, Test)
).dependOn
 
 其中val myTestTask = TaskKey[Unit]("my-test-task")和main, abc, and deff是对Projects的引用。 
 
 聚合仅应用于命令行上指定的顶级任务。 因此，如果您调用my-test-task ，那将是唯一聚合的任务（在这种情况下，它不会在任何子项目上定义，因此不会通过聚合添加任务）。 特别是，它的依赖项（明确列出的test任务）不会被聚合。 结果是，当你调用my-test-task时test in xyz中的test in xyz不会被执行。 
 
 最后，请注意，您可以说xyz/test-only test-only xyz项目运行test-only而不更改为该项目。 

"Aggregation" is the name of the feature that makes test execute on other projects (known as aggregated projects or "execution dependencies") as well as the current one. You can find more information on the Multi-Project Builds page.
 
I would create a custom task in the "main" project that depends on the tasks you want to run. For example,
 
myTestTask <<= Seq(
  test in (main, Test),
  test in (abc, Test),
  test in (deff, Test)
).dependOn
 
where val myTestTask = TaskKey[Unit]("my-test-task") and main, abc, and deff are references to your Projects.
 
Aggregation is only applied to the top-level task specified on the command line. So, if you call my-test-task, that will be the only task aggregated (in this case, it won't be defined on any subprojects, so no tasks get added through aggregation). In particular, its dependencies, the explicitly listed test tasks, don't get aggregated. The consequence is that test in xyz doesn't get executed when you call my-test-task.
 
Finally, note that you can say xyz/test-only to run test-only for the xyz project without changing to that project.
