how to set the contextPath of jetty on xsbt-web-plugin? - jetty

Question

I'm on sbt 0.11.1 and xsbt-web-plugin 0.2.10
here goes the build.sbt and plugins.sbt
build.sbt
organization := "org"
name := "demo"
version := "0.1.0-SNAPSHOT"
scalaVersion := "2.9.1"
seq(webSettings :_*)
configurationXml :=
<configuration>
<webApp>
<contextPath>/foo</contextPath>
</webApp>
</configuration>
libraryDependencies ++= Seq(
"org.eclipse.jetty" % "jetty-webapp" % "7.4.5.v20110725" % "container",
"javax.servlet" % "servlet-api" % "2.5" % "provided"
)
resolvers += "Sonatype OSS Snapshots" at "http://oss.sonatype.org/content/repositories/snapshots/"
project/plugins.sbt
libraryDependencies <+= sbtVersion(v => "com.github.siasia" %% "xsbt-web-plugin" % (v+"-0.2.10"))
It seems the configurationXml doesn't work, after running container:start in sbt console, the contextPath gets the default value "/"
how can I change the contextPath? any tips? thanks in advance!

Here's a solution from scalatra-user group
Add jetty-plus to dependencies:
"org.eclipse.jetty" % "jetty-plus" % "7.4.5.v20110725" % "container"
Add this to build.sbt:
env in Compile := Some(file(".") / "jetty-env.xml" asFile)
In the same directory as build.sbt, create the jetty-env.xml:
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<Set name="contextPath">/foo</Set>
</Configure>
