Problem with org.apache.commons.logging while exporting RCP product [message #523751]

Hi,

I am trying to export my Eclipse RCP product with "Product Export Wizard" and I always have the following error:

Missing requirement: product requires 'org.apache.commons.logging [1.0.4.v200904062259]' but it could not be found

Of course I checked that org.apache.commons.logging was included in my plugin.xml dependencies and my product configuration, but I found out that there were two versions of org.apache.commons.logging: 1.0.4 and 1.1.1. Could the problem be there?

The only topic I found on the subject was http://www.eclipse.org/forums/index.php?t=tree&goto=3334 67& but it got no answer.

If you have any idea to solve my problem, that would be very kind of you.

Thanks in advance,

Armand

(I'm using Eclipse Platform 3.5.2)

I guess this was done intentionally so you can choose the logging bundle for your application yourself. Because of this, you have to add org.apache.commons.logging as required plug-in. Otherwise you will get an error when starting the application:
Missing requirement: Apache Commons Httpclient 3.1.0.v20080605-1935
(org.apache.commons.httpclient 3.1.0.v20080605-1935) requires
'package org.apache.commons.logging [1.0.4,2.0.0)' but it could not be found

does this help you in any way?

Thank you for your help. As a matter of fact, I had added it as a required plugin indeed, but it still couldn't find it.
At last I could solve my problem, and here is the solution if anyone encounters the same problem:

In the product configuration dependencies tab, you have to specify org.apache.commons.logging version with "Properties..." button, in my case 1.1.1, otherwise it will look for version 1.0.4.

I had already tried that, I don't understand why it works now but I won't complain!

Thanks again for your help,

Armand

Hi Armand,

you don't have to add it as dependency to a plug-in, instead add it to your product
(either directly if you have a plug-in based product or via a feature of your application).

btw, I guess this is caused by including the p2.user.ui feature, I opened a bug about the
missing bundle:

I am facing the same problem.

org.apache.commons.logging shows up in my Dependencies, but it has version
1.1.1.v200904062255 while org.eclipse.pde.core requires
1.0.4.v200904062259

I use eclipse-modeling-galileo-SR2-incubation-win32 (downloaded on 2010-04-14).

Am I doing something wrong or is this a bug?

Hi Peter,

you could just try to add the bundle to one of your application features so that it's
included into the exported product. But if you're building a RCP application, it would be
a strange thing to include "org.eclipse.pde.core" except if you're building an application
that includes a Plug-in Development Environment :)

Greetings,

Ralf

Thanks for your reply!

I'm not building an RCP-application - agreed that I wouldn't need it then :)

When I press "Add Required Plug-ins", org.apache.commons.logging is added to my dependencies, so that works fine.

The problem is that the versions do not match. The workaround suggested by Armand works for me too, but I think that something is wrong with either the Dependency or the bundle version.

Best regards, Peter

Select the org.apache.commons.logging and click on properties button where a dialog box will ask you for version number. Give the complete version number as 1.0.4.v200904062259.
And it will work... Very Happy
