[Scons-users] Customize build decision logic for phony targets, that doesn't involve files

[Bill Deegan]

Andrew,

No, Value() is specifically for any value, not just files, so you could
create a Value() node which holds the output from git ls-remote as the
source for your builder.
That should be sufficient, then if it changes, it would cause the builder
to run.
