Hello

After updating the buckminster feature to 1.6.0.v20140801-0035 every action fails. Even buckminster.clean fails with a NPE.

Has anyone seen this error? Anything I can do about it?

Using the DEBUG Logging, I noticed that right before the build fails buckminster attempts to set an ant property:

[ant] Setting ro project property: eclipse.buildId -> 4.4.1.M20140925-0400
[ant] Setting ro project property: osgi.configuration.area.default -> null
org.eclipse.core.runtime.CoreException: BUILD FAILED

The workaround I found to keep my build working was to add the following empty property declarations the configuration/config.ini of my eclipse installation.

osgi.configuration.area.default=
osgi.user.area.default=
osgi.user.area=

This seems like a bug to me, so I filed Bug 448478.

Hi

What version of ANT are you using?

I've noticed that 1.9.4 is now available and it causes some XSLT scripts
to fail under Buckminster 4.2 with apparently undefined variables. I've
yet to diagnose the problem, but bad variable defaults seems
suspiciously similar to your issue.

Regards
