在sbt插件中访问相关项目（非子项目） [英] accessing dependent (not child) projects in sbt plugin

问题描述

请在下面找到使用我们的插件的示例build.sbt文件。
在此示例BasePlugin中，我们想要完整路径到a / project，b / project目录：-

Please find below sample build.sbt file that uses our plugin. In this sample BasePlugin, we want to full path to a/project, b/project directory :-

import sbt._
import Keys._
import BasePlugin._


BasePlugin.settings

lazy val root = Project("root", file(".")).dependsOn(
                                                    ProjectRef( uri("../some/where/a"), "a" ),
                                                    ProjectRef( uri("../some/where/b"), "b" )
                                                )       




enablePlugins(BasePlugin)

此外，在下面找到简化的sbt插件BasePlugin.scala：-

Also, find below, simplified sbt plugin BasePlugin.scala :-

package base

import sbt.{ThisBuild, Def, TaskKey, AutoPlugin}
import sbt._
import Keys._

/**
 * Created by mogli on 4/23/2017.
 */
object BasePlugin extends AutoPlugin {

  object autoImport {
    lazy val customtask: TaskKey[Unit] = TaskKey("customtask")
  }

  import autoImport.customtask


  override def projectSettings: Seq[Def.Setting[_]] = Seq(
    customtask := {
      //expectation: to get an iterator or collection sort of thing for dependent projects, but they are not in this variable (projectDependencies)
      val deps = projectDependencies
      deps map { c => println("project : " + c) }
    }
  )
}

如何在sbt插件中访问依赖项目。

How to access dependent projects in sbt plugin.

推荐答案

要获取项目的依赖项，

val deps = thisProject.value.dependencies.map {dep => dep.project}

如果您在其中访问 thisProject ，这将按预期工作 projectSettings 方法的主体。

This will work as expected if you are accessing thisProject within the projectSettings method's body.
