Doesn't work if more recent clojure exists

[jamesonquinn]

I'm trying to get meteor-load-test working and I think I'm still seeing something like grinder bug 235 on the latest code. Here's what I've done:
-installed meteor-load-test (on OSX with homebrew)
-manually deleted all the 3.11-related files/dirs from ~/.m2/...
-pulled and built 3.12-SNAPSHOT
-edited meteor-load-test/project.clj to refer to 3.12-SNAPSHOT
-run an agent and a console, and pressed "start workers"
and here's the error I get:

...
SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
2014-07-08 10:30:42,016 ERROR worker-bootstrap: Error running worker process
net.grinder.engine.common.EngineException: Clojure is not on the classpath
at net.grinder.scriptengine.clojure.ClojureScriptEngineService.createScriptEngine(ClojureScriptEngineService.java:56) ~[grinder-core-3.12-SNAPSHOT.jar:na]
...

Note that I did NOT deliberately change anything about my clojure version; but I may have had a different version of clojure already installed from something else.

Hi @jamesonquinn, thanks for reporting this.

In the project.clj file, is the clojure dependency set to, [org.clojure/clojure "1.4.0"]?

It should be pulling in the clojure version from the project.clj file so I'm confused why this is happening. On my box I have Clojure 1.5.1 installed as the default but meteor-load-test still uses Clojure 1.4.0 as it should.

Here's a test to try:

1. Run lein repl from your home directory, note the clojure version (1.5.1 for me)
2. Run lein repl from the meteor-load-test directory, note the clojure version (1.4.0 for me)

In case your repl doesn't auto-report the version, you can print it in the repl like this: (clojure-version)

[jamesonquinn]

home: 1.6.0
meteor-load-test: 1.4.0

Yet still, the error. I don't get it.

[alanning]

Hmm, and it didn't work with the stock, Clojure 1.4.0 and The Grinder 3.11 either?

I'm not sure what's happening either. I've done the install with a clean VM both locally (virtualbox) and in the EC2 cloud and its worked before. Could be some change in leiningen that's causing problems here.

One thing you could try is to move your .m2 repo to a totally different location and let lein reinstall all the deps. You should see it download a bunch of stuff when you run lein deps from the project directory. If that still doesn't work then we probably need to set up a Google Hangout to screenshare and figure it out. My contact info is in my github profile.

[jamesonquinn]

I just tried that, and yes, a bunch of stuff reinstalls, but I get the same problem. I think we'll have to troubleshoot in realtime... I've sent you a contact request on google, so let me know there what time is good for you. Thanks!

[alanning]

Good chatting with you. Still not sure why its not working with the pinned Clojure 1.4.0 and Grinder 3.11. But I was able to also get it working with Clojure 1.5.1 and Grinder 3.12-SNAPSHOT.

You'll need to do two things to get it to work:

• Install the latest grinder snapshot from source.

  git clone git://git.code.sf.net/p/grinder/code grinder-code
  cd grinder-code
  mvn -DskipTests install
  

• Update your project.clj file like so:

(defproject meteor-load-test "0.5.1"
    :description "Meteor load testing tool"
    :min-lein-version "2.0.0"
    :url "https://github.com/alanning/meteor-load-test"
    :license {:name "Eclipse Public License"
                          :url "http://www.eclipse.org/legal/epl-v10.html"}
    :dependencies [[org.clojure/clojure "1.5.1"]
                   [org.clojure/data.json "0.2.2"]
                   [com.google.code.gson/gson "2.2.2"]
                   [com.keysolutions/java-ddp-client "0.5.7.5"]]
                   ; :exclusions [org.java-websocket/Java-WebSocket]]
                   ;[com.palletops/java-websocket "1.3.1-SNAPSHOT"]]
    :profiles {:dev
                {:dependencies
                 [[clj-http "0.2.7"]
                  [clj-stacktrace "0.2.4"]
                  [org.clojars.runa/conjure "2.1.3"]
                  [net.sf.grinder/grinder "3.12-SNAPSHOT"]] }}
    :repositories {"sonatype" "https://oss.sonatype.org/content/repositories/releases/"}
    )

Please have a try and let me know how it goes.

[jamesonquinn]

I did as you suggested (to use 1.5.1 and 3.12-SNAPSHOT), and still get the
same problem (though l see 1.5.1 and 3.12 in the classpath and lein repl
etc). I think I'll just do this on some other box, as this one seems to
have its java classes subtly contaminated somehow.

[jamesonquinn]

You may have seen my other bug. Also, I tried installing on a different mac, and I had this same problem. The other is a desktop (imac), also with Mavericks, and has also been used run the applet at gokgs.com. What platform do you use, so I can reproduce that in vbox?

[jamesonquinn]

For future reference: this bug is still a mystery. I'm using a vbox to run the software.

[alanning]

Could it also be related to the Leiningen version? What's the result of lein --version on the Mavericks box?

[jamesonquinn]

2.3.3... so that's not it. Still, it could be that I used homebrew. I'll try doing it direct from the website.

[jamesonquinn]

Nope... same problem still. But while I uninstalled brew's leiningen, I may not have uninstalled all of brew's leiningen dependencies, so that may still be the problem. If someone else has this problem later, that's certainly something I would look at.

[vanamco]

Not sure if this is the same problem, but I got the same message - further down, it told me that the problem was actually a class version problem. I was using java 1.6. Changing to 1.8 fixed it. Running OS X 10.11
