如何在Scala IDE中将源附加到SBT托管依赖项？

Question

我正在使用Scala IDE 2.0.1和SBT 0.11.2从Akka 2.0.1开始.我的build.sbt看起来像这样:

name := "akka"

version := "0.1"

scalaVersion := "2.9.2"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies += "com.typesafe.akka" % "akka-actor" % "2.0.1"

如你所见,没有什么了不起的.

现在,我如何告诉Eclipse将工件与源分类器一起用于akka-actor库？

在SBT中,我可以使用update-classifiers将源代码和Javadocs下载到Ivy存储库,但即使我在从sbteclipse插件运行eclipse命令之前执行此操作,Eclipse仍然不知道源代码.当然,我可以手动执行此操作,但这对于更多库来说不能很好地扩展.

我还尝试将IvyDE插件与deliver-local命令一起使用.虽然这集成了依赖关系管理,但它似乎对源代码没有帮助.

有线索吗？

编辑:这是从deliver-local生成的ivy.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">

    <dependency org="com.typesafe.akka" name="akka-actor" rev="2.0.1" conf="compile->default(compile)"/>
    <exclude org="org.scala-lang" module="scala-library" artifact="*" type="jar" ext="*" matcher="exact"/>
    <exclude org="org.scala-lang" module="scala-compiler" artifact="*" type="jar" ext="*" matcher="exact"/>
    <override org="org.scala-lang" module="scala-library" matcher="exact" rev="2.9.2"/>
    <override org="org.scala-lang" module="scala-compiler" matcher="exact" rev="2.9.2"/>
</dependencies>
</ivy-module>

我是Ivy的新手,所以这并没有告诉我多少.我只是觉得它提到了源代码和javadoc,但不知怎的,IvyDE并没有提起它.

你可以放

EclipseKeys.withSource := true

对你来说build.sbt,这让sbteclipse下载所有资源并让它们在Eclipse中可以访问.请注意,这将从所有已配置的依赖项下载所有源.我不知道如何告诉sbt只下载单个依赖项的源代码.

Answer 2

最后,我找到了一个解决方案,让sbt下载源代码并告诉Eclipse在哪里找到它们.

添加build.sbt:

EclipseKeys.withSource := true

然后运行:

rm -rf  ~/.ivy2/cache/

sbt update-classifiers

sbt eclipse

奇怪的是,如果你已经在ivy中下载了依赖项,那么你将它们放在缓存中,你将无法下载它们的源代码.

好吧，我已经放弃了，回到了 NetBeans 7.1.2 + Scala 插件 + Maven。这种组合集成得更好，开箱即用，无需修改。
