Re: [joshua-support] Tuning error

[Luke Orland]

can you do a grep for output-format to find all the files under a directory where the files you've changed are located?

I have changed some file but i dont know which file because earlier i did not get this error.

This probably means you are using the official version of Joshua, and not the development version.

[Matt Post]

The build.xml file is distributed with Joshua. What would be useful is to see the error message you get.

It looks like you're missing all the dependencies under $JOSHUA/lib/

In the joshua directory /home/bibek/Desktop/joshua-devel/src/joshua/ , run these commands:

export JOSHUA=$PWD

ant devel

"Ivy requires Ant version 1.8.0 or greater. Please upgrade to the latest version."

You should do just that.

[Luke Orland]

If you are in Ubuntu, it looks like you will have to do:

sudo apt-get install ant1.8

[Luke Orland]

It looks like the download url for the ivy jar is being redirected to an IITB mirror that uses SSL (https:// ) but the SSL certificate is missing or bad. I'm not sure at the moment how to prevent the maven server from redirecting to that mirror.

Actually, it seems like the issue may be your school's proxy. Can you use a network with a direct connection to the web, or does all traffic have to go through this proxy?

Are you on a wifi network?

Bibek,

Perhaps the info on this page about using Ivy behind a proxy might lead you toward a solution: http://ant.apache.org/ivy/faq.html

Here are more websites you could check out:
http://www.google.com/#q=ant+ivy+behind+a+proxy&oq=ant+ivy+behind+a+proxy

Please let us know what solution works for you.
