对于我的多项目构建,我尝试创建一个只导致scct:test的验证任务,然后按顺序执行scalastyle。我想scct:test来执行所有子项目,但不是顶层项目。 (如果它是针对顶级项目执行的,我会等待覆盖报告"来自scct,因为该项目中没有来源且没有测试。)我曾想过做的是创建验证作为依赖于scct:test和scalastyle的任务。事实证明这是相当巴洛克式的。这是我的顶级项目/目录中的Build.scala:
object MyBuild extends Build {
val verifyTask = TaskKey[Unit]("verify", "Compiles, runs tests via scct:test and then runs scalastyle")
val scctTestTask = (test in ScctPlugin.Scct).scopedKey
val scalastyleTask = PluginKeys.scalastyleTarget.scopedKey
lazy val root = Project("rootProject",
file("."),
settings = Defaults.defaultSettings ++
ScalastylePlugin.Settings ++
ScctPlugin.instrumentSettings ++
ScctPlugin.mergeReportSettings ++
Seq(
verifyTask in Global := {},
verifyTask <<= verifyTask.dependsOn(scctTestTask, scalastyleTask)
)
) aggregate(lift_webapp, selenium_tests)
lazy val subproject_1 = Project(id = "subproject_1", base = file("subproject_1"))
lazy val subproject_2 = Project(id = "subproject_2", base = file("subproject_2"))
}
但是,验证任务似乎只存在于根项目中;当我运行它时,我看不到在子项目中运行相同的任务。这与我想要的完全相反;我想发布sbt verify
并在每个子项目中运行scct:test和scalastyle,但不在顶级项目中运行。我该怎么做呢?

首先要注意的是,如果您想在某些项目中运行某个任务(verify
,test
等),则需要将它们定义为子项目的范围。因此,在您的情况下,最直接的做法是在verifyTask
和subproject_1
中定义subproject_2
。
lazy val scalaTest = "org.scalatest" %% "scalatest" % "3.0.4"
lazy val verify = taskKey[Unit]("verify")
def verifySettings = Seq(
skip in verify := false,
verify := (Def.taskDyn {
val sk = (skip in verify).value
if (sk) Def.task { println("skipping verify...") }
else (test in Test)
}).value
)
lazy val root = (project in file("."))
.aggregate(sub1, sub2)
.settings(
verifySettings,
scalaVersion in ThisBuild := "2.12.4",
skip in verify := true
)
lazy val sub1 = (project in file("sub1"))
.settings(
verifySettings,
libraryDependencies += scalaTest % Test
)
lazy val sub2 = (project in file("sub2"))
.settings(
verifySettings,
libraryDependencies += scalaTest % Test
)
最近Reddit thread提到了这个问题,所以我发布了我在那里所做的事情。 如果您想手动聚合某些子项目,还有一种名为ScopeFilter的技术。
请注意,我在这里使用的是sbt 1.x,但它应该与sbt 0.13一起进行一些小改动。
lazy val packageAll = taskKey[Unit]("package all the projects")
lazy val myTask = inputKey[Unit]("foo")
lazy val root = (project in file("."))
.aggregate(sub1, sub2)
.settings(
scalaVersion in ThisBuild := "2.12.4",
packageAll := {
(packageBin in Compile).all(nonRootsFilter).value
()
},
myTask := {
packageAll.value
}
)
lazy val sub1 = (project in file("sub1"))
lazy val sub2 = (project in file("sub2"))
def nonRootsFilter = {
import sbt.internal.inc.ReflectUtilities
def nonRoots: List[ProjectReference] =
allProjects filter {
case LocalProject(p) => p != "root"
case _ => false
}
def allProjects: List[ProjectReference] =
ReflectUtilities.allVals[Project](this).values.toList map { p =>
p: ProjectReference
}
ScopeFilter(inProjects(nonRoots: _*), inAnyConfiguration)
}
在上文中,myTask
取决于packageAll
,它会为所有非根子项目聚合(packageBin in Compile)
。

我可能错了,但您只是为当前项目定义了验证任务依赖项。
也许你可以试试:
Seq(
verifyTask in Global := {},
verifyTask <<= (verifyTask in Global).dependsOn(scctTestTask, scalastyleTask)
)
或者您可以将verifyTask设置添加到所有模块中。
