I have the Ivy Eclipse Plugin installed to my Eclipse Luna Service Release 1 (4.4.1).
After creating my ivy.xml and selecting Add Ivy Library I get this error in the logfile:

Could somebody see, what I'm doing wrong?

Answer 1

For me updating to the latest Alpha release helped.
HOWTO:
1)
Uninstall the old Ivy eclipse plugin.
Help->Installation details->Installed Software, select all Apache Ivy entries and hit the uninstall button.
2)
Restart Eclipse
3)
Add a new update site:
Help->Install new software->Add...
Name: "IvyDE Alpha-Builds Update site"
Location: "https://builds.apache.org/job/IvyDE-updatesite/lastSuccessfulBuild/artifact/trunk/build/"
Hit the "OK" button to add the update site.
4)
In the "Install" dialog, select the "IvyDE Alpha-Builds Update site" from the "Work with:" drop down menu.
Select and install the desired plugins from the list.
It also fixed a problem with the context menus I encountered after updating Eclipse Luna to SR1.
