can't run monkeybars example

I get the following when attempting to setup the project for the monkeybars example:

C:\Users\cod2\Documents\NetBeansProjects\bookie>jruby -S rake generate ALL=src/bookie
(in C:/Users/cod2/Documents/NetBeansProjects/bookie)
rake aborted!
Don’t know how to build task ‘generate’

thanks

Hi, Charles.

I’ve seen issues like this before if I ran the generate step before the rawr step. Have you run rawr install from inside the project directory?

If the error persists even after doing another rawr install, can you post the versions of the monkeybars and rawr gems on your system? I can try to recreate the issue here. (I may need a few days before I have access to a Windows 7 machine, but I will eventually be able to try it.)

thanks , I’ll try to get back to this , but I first decided to conquer the generating of jars which I’m posting about an issue now

Hello all,

I followed the monkeybars example on the book, but I have a traceback when I attempt to add/use the RedCloth lib.

In particular, I have a traceback:

Exception in thread “main” org.jruby.exceptions.RaiseException: (LoadError) no such file to load—redcloth at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1033) at (Anonymous).(root)(C:/Documents and Settings/roberto.gianassi/Documenti/WORK/hello/build/classes/manifest.rb:61) ...

The manifest.rb around line 61 is:

add_to_load_path ’../lib/ruby/redcloth/lib’
require ‘redcloth’

require ‘swing_ext’

so nothing strange.

The RedCloth library is there.

I’m new to Ruby and jRuby, so I’m probably missing something stupid, but I don’t know what to debug.

Hi, Roberto.

Sorry about this error. I’m not around a machine where I can test this, but I can look into it next week. In the meantime, you may be able to load the RedCloth file using its absolute path.

Hi Ian,

thank you for your replay. No problem about the error: that’s software!

After some more investigation it seems something related to rake 0.8.4. Some slashes are not handled correctly.

So I have now 2 questions:
1. How may I downgrade to rake 0.8.3?
2. I see on rake site that last rake version is 0.8.7. I tried jruby -S gem update, but it doesn’t update anything and it says all is up-to-date. Is there any reason to not update to last version? Is possible, in some way, to force the update to a specific rake version?

Thanks again,
Roberto

Hi, Roberto.

I was able to replicate the no such file error; it looks like in more recent versions of NetBeans / monkeybars, the redcloth directory wasn’t getting copied into the build folder.

Here’s how I got it running again on my machine. In the Projects pane, right-click on Libraries and choose Add JAR/Folder.... Browse to lib/ruby/redcloth/lib and click Open. The next time you run your app from NetBeans, it will copy RedCloth into the build folder where it needs to be.

In answer to your follow-up questions:

1. You can type jruby -S gem uninstall rake, followed by jruby -S gem install rake -v '=0.8.3'.
2. Rake 0.8.7 may indeed work better for you. Try jruby -S gem update rake or jruby -S gem install rake.

Hope this helps.

It works!

Thank you and Happy Easter!
