注释处理器输出路径sbt？

Question

有没有办法在sbt中设置注释处理器输出路径？

目前，它将文件生成为：

target/scala-2.11/classes

不过，我更希望

target/scala-2.11/src_managed

Answer 1

有点像

// 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稍微更符合人体工程学。

在build.sbt中添加到sbt模块的设置

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

您也可以将这个插件放到project文件夹中。

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)
  )
}

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")
