在sbt-native-packager中擴展「通用」配置

Question

我正在使用sbt 0.13.8和sbt-native-packager 1.0.3。

我想用不同的java選項設置開發和生產打包配置。這個想法是通過UniversalPluguin從sbt-native-packager : "universal:packageZipTarball"創建一個軟件包壓縮包。我也使用「JavaServerAppPackaging」原型。

我想這Build.scala：

Error:Error while importing SBT project:

[error] Use 'last' for the full log.

我創造與SBT命令「dev:packageZipTarball發展的兩個壓縮包打包的想法背後：

import sbt._ 
import Keys._ 
import com.typesafe.sbt.packager.universal.UniversalPlugin.autoImport._ 
import com.typesafe.sbt.packager.archetypes.JavaServerAppPackaging 

object Build extends Build { 

    lazy val commonSettings: Seq[Setting[_]] = Seq(
    scalaVersion := "2.11.7", 
    crossScalaVersions := Seq("2.11.7"), 
    scalacOptions in Compile ++= Seq("-unchecked", "-feature", "-language:postfixOps", "-deprecation") 
) 

    lazy val devConfig = config("dev") extend Universal 
    lazy val prodConfig = config("prod") extend Universal 

    lazy val root = (project in file(".")) 
    .settings(commonSettings : _*) 
    .enablePlugins(JavaServerAppPackaging) 
    .configs(devConfig, prodConfig) 
    .settings(
     javaOptions in devConfig ++= Seq(
     // -J params will be added as jvm parameters 
     "-J-Xmx384m", 
     "-J-Xss512k"), 
     javaOptions in prodConfig ++= Seq(
     // -J params will be added as jvm parameters 
     "-J-Xmx384m", 
     "-J-Xss740k") 
    ) 
} 

使用這個配置，SBT保持與失敗「，並用」prod:packageZipTarball「生產不同的jvm選項。

任何想法爲什麼我不能使用自定義配置來擴展「universal」配置以實現該方法或替代方法？

Answer 1

我強烈建議不要擴展配置。行爲不是預期的行爲。實現不同構建配置的最佳方法是爲每個配置創建子模塊。

請參閱this answer，其中詳細解釋瞭如何創建具有不同配置的子項目。
