Hello
I have Myeclipse 6.0.1
Build Id 6.0.1-GA-200710
I am doing SWT or RCP development through plug in projects…
when I try to export the plugin using this phrase ‘Eclipse Product Export wizard’ I get a circular dependancy error that says ‘ A cycle was detected when generating the classpath’.
If I try to export a plugin individually I still get the same error. I have checked all the plugins using ‘dependency analysis’ and did not find any cycles but I still get this error.
I was wondering if someone could help me out here.
thanks

I didnt undertand how you are exporting your project. Can you list the steps for me.

Are there any errors being logged under <workspace>/.metadata/.log file.

Hi Nipun
Thanks for your reply…Is there a way to send you attachments.
Anyways I have tried to document the steps below, By the way the same procedure for the same project with the same manifest files works in MyEclipse 5.1.0.

Steps
1. I right click on a project in the Navigator view and select export from the context Menu.
2. Under the resulting ‘Export’ dialog under the ‘plug-in Development’ folder, I select ‘Deployable plug-ins and fragments with AspectJ support’
3. I then click on ‘Next’ and then ‘finish’
MyEclipse then starts doing its mojo but fails with the error ‘A cycle was detected when generating the classpath’, It shows a dialog with a list of few jars..one of them is ours…the same information is printed into the log file under
<workspace>/.metadata/.log. I am reproducing the same

!ENTRY org.eclipse.pde.build 4 14 2007-11-16 09:34:35.453
!MESSAGE A cycle was detected when generating the classpath org.calgb.domain_0.5.0, org.eclipse.ui_3.3.1.M20070910-0800b, org.eclipse.swt_3.3.2.v3347, org.eclipse.atf.mozilla.ide.core_0.2.2.zmyeclipse601200710, org.eclipse.atf.core_0.2.2.zmyeclipse601200710, org.eclipse.ui_3.3.1.M20070910-0800b.

org.calgb.domain_0.5.0 is our project that I right clicked on from the Navigator view..

Hope this helps..I can send attachments if you tell me where to or how..
thanks

You can pm the attachment to me. You can do this by clicking the pm button at the bottom of my post.

Also, please go to MyEclipse > Installation Summary > Installation Details and paste the information here for me so that I can try reproducing this with the same configuration.

It seems like you have loads of pluings installed with MyEclipse. They could be causing a conflict here. Can you send me the project so that I can try exporting it with a clean install ? Or you can install MyEclipse to a brand new location and try exporting your project to make sure that this is not being caused by plugins.

Hi Nipun
I tried exporting it with bare minimum the only plugins I had were eclipse-RCP-3.3.1.1-delta-pack (need this to do a build for mac) and AspectJ along with eclipse plugin environment and it still failed…do you still need the project

[rsood]

ok ignore my previous message..it did work with those plugins..i am now going to add other plugins and will let you know

[Loyal Water]

Thanks for updating me.

Nipun
Thanks for your help, it all worked out..I finally added the following additional plugins testing after adding each plugin if the expot would work. Compared to last time I avoided adding plugins that I did not need or were marked (incubation)

1. RCP Delta Pack
2. Mylin
3. AspectJ
4. Plugin Development
5. JIRA
6. Subclipse
7. BuckMinster for core, maven, pde support
8. Q4e
9. Jadeclipse
10. Matisse
11. Eclipse updates except rcp patch it has a strange red square box overlay to it ( any idea what it means), anyways it has caused trouble in the past
12. Birt reporting
13 GEF

thanks again for your help , really appreciate it.
