[英]How to get setting value of another project in multi-project build
I`m not sure that I get right the concept of sbt workflow.我不确定我是否正确理解了 sbt 工作流程的概念。 I have multi-project structure of an arbitrary depth in my build.sbt Now I want to define task which can show me library dependencies of project current subprojects depends on.
我的构建中有任意深度的多项目结构。sbt 现在我想定义可以显示项目当前子项目所依赖的库依赖项的任务。 Or, in common: is there any way to get setting value of another project?
或者,共同点:有没有办法获得另一个项目的设定值?
I`m trying to do somthing like this:我正在尝试做这样的事情:
val hierarchyDeps = taskKey[Seq[ModuleID]]("")
val hierarchyDepsImpl = Def.task {
loadedBuild.value.allProjectRefs.flatMap { case (projectRef, resolvedProject) =>
(projectRef / libraryDependencies).value
}
}
val cmn = project.in(file("cmn"))
val subA = project.in(file("sub_a")).dependsOn(cmn).settings(hierarchyDeps := hierarchyDepsImpl.value)
val subB = project.in(file("sub_b")).dependsOn(cmn).settings(hierarchyDeps := hierarchyDepsImpl.value)
but getting java.lang.IllegalArgumentException
:但得到
java.lang.IllegalArgumentException
:
java.lang.IllegalArgumentException: Could not find proxy for val projectRef: sbt.ProjectRef in List(value projectRef, value $anonfun, method $anonfun$hierarchyDepsImpl$1, value hierarchyDepsImpl, object $5879c5c8d08c0b0b007a, package <empty>, package <root>) (currentOwner= value hierarchyDepsImpl )
I think you are trying to do something outside of sbt philosophy.我认为您正在尝试在 sbt 哲学之外做一些事情。
You should define a task for each project that does something.你应该为每个做某事的项目定义一个任务。 Then add
aggregate
to your root project with the list of all sub-projects.然后使用所有子项目的列表将
aggregate
添加到您的根项目中。 Thus, when you call sbt taskName
, it will call taskName
for all sub-projects in aggregate
.因此,当您调用
sbt taskName
时,它将为所有子项目调用taskName
aggregate
。
Also, what you want to do can be just done with following另外,您想做的事情可以通过以下方式完成
sbt "show libraryDependencies"
given that you defined aggregate
for your root project假设您为根项目定义了
aggregate
val root = project.in(file(".")).aggregate(cmn, subA, subB)
