It seems that since eclipse v4.7.1a (fresh install), it is no more possible to execute any ant build.
Each time it fails with the following message:
Launch configuration <name of build file> references non-existing project <name of the containing project>
We have tested it with many different configuration (eclipse-jee, eclipse-rcp ...), each time with a fresh eclipse v4.7.1a install.
After further investigation, this occurs only if the build.xml file in not under a "java" kind of project, which is the case for all of our workspaces (30+...).
Everything worked well with v4.7.0
In the .logfile we can see:

[UPDATE]
If the build.xml file is inside a Java project. Everyhting works fine as before
If the build.xml file is in a regular project or a EAR project (our case) it does not work...
It seems there is a way to make it work in those cases:
- right click on build.xml
Run As->Ant Build...-> Select the "JRE" tab,- check "
Run in the same JRE as the workspace"...
and it works as before...
It is clearly a regression from previous version...
