• Status: Resolved

Environment

Description

When starting eclipse all projects with any ivy dependency library in their build path generate this error :

An internal error occurred during: "Resolve project 'acceptance' and ivy file 'ivy.xml' dependencies".

I also notice that although the ivy.xml file is still present in the project root the library entry (which usually appears underneath the JRE System Library entry) is not present.

Work Around
-----------
If I remove the ivy library from the build path , close the dialog and then re-open the dialog and re-attached the ivy library then everything compiles correctly.

ivy.properties
--------------
org.name=tallyman
repository.root=**REDEDACTED*
ivy.repository=/tallyman/ivyrepos/trunk
ivy.resolver.default.check.modified=true
trunk.dir=${ivy.settings.dir}/..
ivy.cache.dir=${trunk.dir}/.ivycache
svn.user=
svn.password=

I've redacted the repository.root but it's just a standard http: based svn location, of the form http://server/svn/product - I'm making sure I don't end up in the smelly stuff with my manager.
