[cdt-dev] Unable to build CDT from latest source

[Avi Kivity <avi@xxxxxxxxxxxx>]

Hello, heroic CDT developers,

I regularly build CDT from source (since I need a patch, not good enough for upstream, for C++14 lambdas).  I just hit an error with git master:

[ERROR] Failed to execute goal org.eclipse.tycho.extras:tycho-eclipserun-plugin:0.25.0:eclipse-run (default) on project org.eclipse.cdt.doc.user: Error while executing platform: Error while executing platform (return code: 13) -> [Help 1]

Here is the log:
