SBT,Jetty和Servlet 3.0

Question

我有一个非常小的问题.

我有以下build.sbt文件:

name := "Tueet"

libraryDependencies += "org.eclipse.jetty" % "jetty-webapp" % "8.1.2.v20120308"

在调用sbt update之后,我得到以下内容:

这很愚蠢,因为它在Maven中无效.我发现这是因为Orbit用包装做了一些事情(他们明确地将它设置为轨道).

我尝试做了exclude("org.eclipse.jetty.orbit","javax.servlet"),但没有发生任何事情,它仍然需要依赖.

我找不到任何关于如何实际解决这个问题的信息,也许有人会在这里帮助我:)

更新:提供的错误提供了一种解决方法,因此为了解决这个问题,我实际上将build.sbt更改为

name := "Tueet"

libraryDependencies += "org.eclipse.jetty" % "jetty-server" % "8.1.2.v20120308"

ivyXML := 
<dependency org="org.eclipse.jetty.orbit" name="javax.servlet" rev="3.0.0.v201112011016">
<artifact name="javax.servlet" type="orbit" ext="jar"/>
</dependency>

Answer 1

看到这个bug:https://jira.codehaus.org/browse/JETTY-1493

问题的症结在于常春藤不支持轨道延伸,需要将轨道包装类型映射到jar.不确定你是否使用常春藤,但根本原因是相同的,你可以看到它是从maven中心下载的网址.

这个bug有一点背景,我们首先切换到这些依赖项.

Answer 2

我找到了一个解决方法.更多信息可以在这里找到:SBT,Jetty和Servlet 3.0.

classpathTypes ~= (_ + "orbit")

libraryDependencies ++= Seq(
  "org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" % "container"         artifacts (Artifact("javax.servlet", "jar", "jar")
  )
)

libraryDependencies ++= Seq(
  "org.eclipse.jetty" % "jetty-webapp" % "8.1.4.v20120524" % "container" artifacts            (Artifact("jetty-webapp", "jar", "jar"))
)
