error when running build.sh

[cristinadp]

I am getting the following error:

$ bash -x build.sh
....

[error] Server access Error: Network is unreachable (connect failed) url=http://nexus.opencollab.co.za/nexus/content/repositories/releases/coza/opencollab/epub/epub-creator/1.0.3-GDL/epub-creator-1.0.3-GDL.pom

Apparently, nexus.opencollab.co.za has been down the whole day...

Is there an OpenCollab Nexus Repo mirror that I could use? Thanks!
