nightly extension builds
Indeed, looking at the dashboard only few extensions are build. See here

I am looking into it and will report back.

Look at the log, I found:

[  7%] Building CXX object ScanConvertPhasedArray3D/CMakeFfatal: reference is not a tree: aaedd3e108ae3f07f38aa517b14bc00b86ded170
CMake Error at XNATSlicer-prefix/tmp/XNATSlicer-gitclone.cmake:75 (message):
  Failed to checkout tag: 'aaedd3e108ae3f07f38aa517b14bc00b86ded170'

This is causing the extension build process to stop because checkout of extension sources is not sandboxed. Currently only the build and test steps are.

Here is the commit that recently implemented sandboxing for the test step: r25439

I am working on a fix.
