在Build.scala
中,项目之间存在依赖关系:
val coreLib = Projects.coreLib()
val consoleApp = Projects.consoleApp().dependsOn(coreLib)
val androidApp = Projects.androidProject().dependsOn(coreLib/*, exclusions = xpp */)
核心库项目在其libraryDependencies
(XPP解析器)中定义了一个库,我想在androidApp
中排除它,因为Android框架有自己开箱即用的XPP实现。
如何从coreLib
项目中androidApp
的传递依赖项中排除XPP库?
编辑:
根据我的研究,排除仅适用于与ModuleID
一起使用的libraryDependency
。同时dependsOn
将所有传递依赖项放到classpath中,api无法排除此项目的某些传递依赖项,dependsOn
详情:
我目前正在运行sbt 0.13.5。
commonLib的 libraryDependencies
以及build.sbt中提供的各种设置,以便此项目可以作为独立项重用,并且因为它感觉sbt
中提供设置的权利和自然方式。< / p>
答案 0 :(得分:33)
这似乎对我有用:
val someApp = project.settings(
libraryDependencies += "junit" % "junit" % "4.11"
)
val androidApp = project.dependsOn(someApp).settings(
projectDependencies := {
Seq(
(projectID in someApp).value.exclude("junit", "junit")
)
}
)
projectDepenendencies正在做的是默认情况下sbt尝试做什么。它将任何项目间依赖项转换为ModuleID
s,Ivy将在解析期间使用它们。由于Project
API无法指定当前的排除,我们会绕过此自动图层并手动声明Ivy依赖项。
结果:
> show someApp/update
