java.io.FileNotFoundException: Could not locate clojure/contrib/duck_streams__in
it.class or clojure/contrib/duck_streams.clj on classpath: (NO_SOURCE_FILE:0)
Clojure.contrib is in CLASSPATH still it is throwing Exception. Do I need some other Jar?
Use clojure.java.io instead, it's included with 1.2.
I highly recommend using leiningen to sort this out.
try the lein repl command to get a quick repl with a working classpath.
According to this message:
http://osdir.com/ml/clojure/2010-10/msg00834.html
clojure.contrib.duck-streams has been deprecated.

When I add :repl-options {:init (print "x..")} to ~/.lein/profiles.clj it does what it should on every repl start-up. however, when I add the same to my local project.clj, I receive this error:
Exception in thread "main" java.lang.RuntimeException: Unable to resolve symbol: do in this context, compiling:(/tmp/form-init5885833654225579206.clj:1:886)
I'm using leiningen 2.5.3
I've stumbled across this issue as well - I tried to use multiple profiles, each with its own :repl-options.
The issue is that Leiningen doesn't merge `:init: correctly. You can refer to this issue for more details.
Unfortunately, I couldn't find any fix that would work for me. And the issue itself won't be fixed till Leiningen 3.0.
I am trying to setup autotest for midje. Currently, running lein midje works. However running lein midje :autottest gives me the stack trace below.
I run through my different namespaces and they all compile

See this: https://github.com/marick/Midje/issues/215
It says:
If a file being loaded by Midje at startup has a parse error (a reference to an unknown
symbol, etc.) that prevents it from being loaded successfully, Midje swallows the original
load error and instead prints the following error, which is much less useful.
I have suffered from this too: any little typo brings up this misleading error message.
I remember having problems with autotest and namespaces that :require or :use other namespaces using the [prefix ns1 ns2 ...] form. So, the following did not work:
(ns abc
(:use [abc def ghi]))
while this was okay:
(ns abc
(:use abc.def
abc.ghi))
Are you using that kind of syntax?
Programmin Clojure by "Stuart Halloway" book talks about Lancet, Very first step is (use 'lancet) which is throwing some Exception,
Exception
user=> (use 'lancet)
java.io.FileNotFoundException: Could not locate lancet__init.class or lancet.clj
on classpath: (NO_SOURCE_FILE:0)
Is any jar file or some package is required to make this work?
You need lancet installed to use lancet. I'm surprised the book doesn't mention anything like that. Anyway, I would strongly recommend you use leiningen instead. Lancet is out of date and leiningen is the most popular build tool for clojure these days.
I am trying to compile some Clojure code to Java using the Clojure 1.2 compiler. I am including the Clojure and Clojure-contrib 1.2 jars in the classpath. When I do the compile it fails and I get the folowing error:
Exception in thread "main" java.lang.ClassNotFoundException: clojure.contrib.io.Streams (io.clj:121)
: Has anyone seen this before?
Update:
Here is the line I use to compile my clj files:
java -cp "..\lib\h2.jar;..\lib\vaadin-6.4.4.jar;..\lib\clojure.jar;..\lib\clojure-contrib.jar;..\lib\wlfullclient-10.3.0.0.jar;..\..\..\..\..\jre1.6windows32bit\lib\rt.jar;." -Dclojure.compile.path=cljclasses clojure.lang.Compile oe.main.oe-main
clojure.contrib.io.Streams is a protocol defined in clojure.contrib.io
To help you more you have to share more details about how and what you are trying to compile.
use (compile 'oe.main.oe-main) from a clojure REPL using the same class path, and this works
I'm playing around with Clojure, and I can't figure out how to import a function from clojure-contrib.jar. Working from this answer, I'm doing the following:
Running the REPL like so:
java -cp clojure.jar:clojure-contrib.jar clojure.main
Then trying to import a function:
user=> (use '[clojure-contrib.duck-streams :only (writer reader)])
It doesn't work, and I get the following error:
java.io.FileNotFoundException: Could not locate clojure_contrib/duck_streams__init.class or clojure_contrib/duck_streams.clj on classpath: (NO_SOURCE_FILE:0)
Trying it with a dot instead of a dash also doesn't work:
user=> (use '[clojure.contrib.duck-streams :only (writer reader)])
I get mostly the same error:
java.io.FileNotFoundException: Could not locate clojure/contrib/duck_streams__init.class or clojure/contrib/duck_streams.clj on classpath: (NO_SOURCE_FILE:0)
What am I doing wrong?
Is clojure.jar and clojure-contrib.jar in your current working directory? If not, you need to specify the full path to the JAR files in the CLASSPATH.
This should work
(use 'clojure.contrib)
I don't have clojure handy right now to check, but
(use 'clojure.contrib :only (writer reader))
should also work
It's clojure.contrib, not clojute-contrib. Note dot versus dash.
