I too have this same problem on Eclipse Indigo (3.7), when trying to upgrade Jaspersoft Studio from 1.1.2 to the latest version 1.3.1 :

An error occurred while collecting items to be installedsession context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).No repository found containing: osgi.bundle,org.eclipse.nebula.cwt,0.9.0.201210100641No repository found containing: osgi.bundle,org.eclipse.nebula.widgets.cdatetime,0.14.0.201210100641

The above error looks like it needs the Nebula Widgets. In the Eclipse Marketplace (Help menu), I searched on 'nebula' and found 'Nebula Stable Widgets' which I installed. This made the installation get a lot further. Is this something that can be installed automatically when doing the JasperStudio plugin install/update?

Now I get the following error:

Cannot complete the install because one or more required items could not be found.Software currently installed: Jaspersoft Studio 1.3.1 (com.jaspersoft.studio.feature.feature.group 1.3.1)Missing requirement: Data Adapters 1.3.1 (com.jaspersoft.studio.data 1.3.1) requires 'bundle org.apache.commons.pool 1.6.0' but it could not be foundCannot satisfy dependency:From: Drivers 1.3.1 (com.jaspersoft.studio.data.drivers 1.3.1)To: bundle com.jaspersoft.studio.data 1.3.1Cannot satisfy dependency:From: Jaspersoft Studio 1.3.1 (com.jaspersoft.studio.feature.feature.group 1.3.1)To: com.jaspersoft.studio.data.drivers [1.3.1]

I located a jar elsewhere on my system (org.apache.commons.pool_1.6.0.v201204271246.jar) and copied it into the eclipse plugins dir.

Now this apache-xalan is missing:

Missing requirement: JasperReports Library and Tools 4.8.1 (net.sf.jasperreports 4.8.1) requires 'bundle org.apache.xalan 2.7.1' but it could not be found

I will stop now because I expect to have many more missing dependencies. Is there some way that the installer can be configured to install ALL bundles that it needs?

I got past the original dependency error as well. But have had to install dependency after dependency manually. I am currently stuck on org.eclipse.equinox.p2.artifact. I agree downloading all dependencies would be most helpful.

Hi guys,the plugin installation was already tested before release for both 3.6/3.7/3.8 and worked fine.I tried to replicate right now your problem installing the plugin in an Indigo Java for Developers version 3.7.2. I both tried from Market Place and plugin from update site http://jasperstudio.sf.net/updates/They worked both and after restart I was able to create and run a Coffee report using the SampleDB.Are you sure that the flag "Contact all update sites during install to find required software" is enabled?Right now we suggest a set of update sites in order to smoothly install all needed dependencies (i.e: Xtext, Xalan, Nebula Widgets etc.), so the user does not have to install all the required stuff by itself.From a technical point-of-view we do this during the update site building, where the final content.jar file is enriched using the information inside the associateSites.xml.Can please try to verify if you have the sites listed in here (http://jasperstudio.sourceforge.net/updates/associateSites.xml) among the "Available software sites"? From Preferences under Install/Update.Maybe for some reason they are not enabled, but they were added during the unsuccessful installation you tried.Another thing... what JDK are you currently using? JDK 1.6 or 1.7?Regards,Massimo.

Thx for your help. My issue appears to have been eclipse based. Ultimately I had to uncheck the contact all sites flag, get out of eclipse and turn it back on. Once I did this it appears to have worked fine.

Ok perfect. Glad you were able to solve it. Let's see if also robnewton had the same problem. For now I will keep the bug open, I will close it maybe at the beginning of the next week.

I wasn't sure if I should start a new thread or not.

I tried unchecking and re-checking the "Contact all update sites during install" option, but I didn't exit Eclipse in-between like dprokosch did, so that didn't help.

However, as per advice from mrabbi, I examined the associated sites xml file, and then looked for them in my "Available Software Sites". They were there, but they were not checked. So I checked them, but still had a problem with missing the apache-xalan bundle. So I checked one other that seemed related, and they install finally worked! As dprokosch suggests, our Eclipse must be a bit messed up.

The given associated sites were:

http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/http://download.eclipse.org/tools/orbit/downloads/drops/R20120526062928/repository/http://download.eclipse.org/technology/nebula/snapshot

The extra one I needed to check was one of these (I cannot remember exactly which one):

http://download.eclipse.org/modeling/tmf/xtext/updates/http://download.eclipse.org/modeling/tmf/xtext/updates/

Any way, it is working OK now. Many thanks mrabbi for the quick response.

Hi guys,I will close this bug.dprokosch could you please open a new one attaching a txt with the exception you got? Thanks.However, could you please first try to uninstall the Studio plugin and re-install it. Just to try if this can fix the problem.Moreover can you give me some more details about your actual Eclipse configuration? Plus JDK version etc.In your stacktrace I saw something related to Python... so probably you are using PyDev or something similar.With a quick overview I can maybe be able to reproduce the problem. If you can solve the problem with uninstall-reinstall attach a comment here, you should be able to do it even if the bug is closed.If you can not, feel free to open the new bug with all the details (steps, configuration, stacktrace txt ,etc.).Massimo.
