注释处理器输出路径sbt

Question

有什么方法可以在sbt中设置Annotation处理器输出路径吗？

目前它将文件生成为：

target/scala-2.11/classes

不过我更喜欢

target/scala-2.11/src_managed

Answer 1

类似的东西

// in build.sbt:
// create managed source directory before compile
compile in Compile <<= (compile in Compile) dependsOn Def.task { (managedSourceDirectories in Compile).value.head.mkdirs() },
// tell the java compiler to output generated source files to the managed source directory
javacOptions in Compile ++= Seq("-s", (managedSourceDirectories in Compile).value.head.getAbsolutePath),

Answer 2

配置sourceManaged而不是managedSourceDirectories稍微符合人体工程学。

添加到build.sbt:中sbt模块的设置

Compile / javacOptions ++= Seq("-s", (Compile / sourceManaged).value.getAbsolutePath)

您也可以将此插件放入project文件夹

package custom.sbt
import sbt.{Def, _}
import sbt.Keys._
object Compiler extends AutoPlugin {
  override def trigger = allRequirements
  override def buildSettings: Seq[Def.Setting[_]] = Seq(
    Compile / javacOptions ++= Seq("-source", "11", "-target", "11"),
    scalacOptions ++= Seq(
      "-target:11"              // Target JRE 11
    )
  )
  override def projectSettings: Seq[Def.Setting[_]] = Seq(
    Compile / javacOptions ++= Seq("-s", (Compile / sourceManaged).value.getAbsolutePath)
  )
}

Answer 3

在sbt 0.13.15 中

compile := ((compile in Compile) dependsOn Def.task {
      (sourceManaged in Compile).value.mkdirs()
    }).value,
javacOptions in Compile ++= Seq("-s", s"${sourceManaged.value}/main")
