I have the following jars under /Users/joe/.scala/lib:
commons-codec-1.4.jar
httpclient-4.1.1.jar
httpcore-4.1.jar
commons-logging-1.1.1.jar
httpclient-cache-4.1.1.jar
httpmime-4.1.1.jar
Below is my test.sh written in scala.
#!/bin/sh -v
L=`cd /Users/joe/.scala/lib;pwd`
cp=`echo $L/*.jar|sed 's/ /:/g'`
echo $cp
exec scala -classpath $cp $0 $@
!#
println(new org.apache.commons.httpclient.HttpClient())
Here is the error that I get:
$ ./test.sh
#!/bin/sh -v
L=`cd /Users/joe/.scala/lib;pwd`
cd /Users/joe/.scala/lib;pwd
cp=`echo $L/*.jar|sed 's/ /:/g'`

/Users/joe/Desktop/scala/./test.sh:7: error: object httpclient is not a member of package org.apache.commons
println(new org.apache.commons.httpclient.HttpClient())
^
one error found
However, simple ones without any classpath dependencies work though: hello.sh
#!/bin/sh
exec scala "$0" "$@"
!#
println(new java.util.Date())
Any idea what I am doing wrong in the first example? Alternatively, what is the best way to set classpath dependencies when working with scala scripts?
I'm not going to answer your question, but you might be interested in this.
Suppose you download and install SBT (version 0.10.0 or higher), and create a shell script called "scalas":
java -Dsbt.main.class=sbt.ScriptMain \
-Dsbt.boot.directory=/home/user/.sbt/boot \
-jar sbt-launch.jar "$@"
And then you write your script like this:
#!/usr/bin/env scalas
!#
/***
scalaVersion := "2.9.1"
libraryDependencies ++= Seq(
"commons-codec" % "commons-codec" % "1.4",
"org.apache.httpcomponents" % "httpclient" % "4.1.1",
"org.apache.httpcomponents" % "httpcore" % "4.1",
"commons-logging" % "commons-logging" % "1.1.1",
"org.apache.httpcomponents" % "httpclient-cache" % "4.1.1",
"org.apache.httpcomponents" % "httpmime" % "4.1.1"
)
*/
println(new org.apache.http.client.DefaultHttpClient())
I think with 4.1.1 the class is org.apache.http.client.HttpClient instead of org.apache.commons.httpclient, and it's an interface. So you might want
new org.apache.http.client.DefaultHttpClient()
instead of
new org.apache.commons.httpclient.HttpClient()
It might well have been different in an earlier version.
