如何在playframework 2.1.1中配置aspectj编译

Question

我已将此声明添加到plugins.sbt中

addSbtPlugin("com.typesafe.sbt" % "sbt-aspectj" % "0.9.0")

现在我想配置这个插件，使用方面库org.springframework:spring-aspects:3.1.4编译我的java控制器类，就像使用aspectj-maven-plugin一样

我已经设置了这个配置：

import sbt._
import Keys._
import play.Project._
import com.typesafe.sbt.SbtAspectj._
import com.typesafe.sbt.SbtAspectj.AspectjKeys._

object ApplicationBuild extends Build {

    val appDependencies = Seq(javaCore)

    val main = play.Project(appName, appVersion, appDependencies).settings(
        AspectjKeys.verbose in Aspectj := true,
        AspectjKeys.showWeaveInfo in Aspectj := true,
        AspectjKeys.inputs in Aspectj <+= compiledClasses
    )

}

但它确实失败了。

[error] Reference to undefined setting: 
[error] 
[error]   aspectj:inputs from aspectj:inputs

我真的是sbt的新手。

好的，我让它工作，感谢sbt邮件列表，cf。https://groups.google.com/forum/?fromgroups=#!topic/simple-build-tool/MUXyfKigC7w

以及播放框架邮件列表，参见。https://groups.google.com/forum/?fromgroups=#!topic/play-framework/RfJFEwVbUUk

事实上，这并不是很难，但却是你看不到的东西。

import sbt._
import Keys._
import play.Project._
import com.typesafe.sbt.SbtAspectj._
import com.typesafe.sbt.SbtAspectj.AspectjKeys._

object ApplicationBuild extends Build {

    val appDependencies = Seq(javaCore, filters)

    val main = play.Project(appName, appVersion, appDependencies)
            .settings(aspectjSettings: _*)
            .settings(
                    libraryDependencies += "org.springframework" % "spring-aspects" % "3.1.4.RELEASE",
                    libraryDependencies += "org.springframework.security" % "spring-security-aspects" % "3.1.4.RELEASE",
                    sourceLevel := "-1.7",
                    verbose in Aspectj := false,
                    showWeaveInfo in Aspectj := false,
                    inputs in Aspectj <+= compiledClasses,
                    binaries in Aspectj <++= update map { report =>
                        report.matching(
                                moduleFilter(organization = "org.springframework", name = "spring-aspects")
                                || moduleFilter(organization = "org.springframework.security", name = "spring-security-aspects")
                        )
                    },
                    products in Compile <<= products in Aspectj,
                    products in Runtime <<= products in Compile
                )
}

别忘了在plugins.sbt中添加这个，在声明之间加一个新的行分隔符

addSbtPlugin("com.typesafe.sbt" % "sbt-aspectj" % "0.9.0")
