Should we ditch lfc -r (rebuild)?

[cmnrd]

I am trying to fix the rebuild option of lfc (see #521 and #524). While working on this, it occurred to me that the rebuild causes quite some trouble. While we can certainly fix the discussed issues, the whole thing seems to be pretty fragile. And we need to be aware that this mechanism only works in a developer setup. If we take a pre-built lfc and run lfc -r bad things will happen.

I am thinking that we should let gradle handle the building altogether (it's what it is made for after all). We already have the buildLfc target for gradle. So instead of using lfc -r we could simply do ./gradlew --runLfc --args, which will rebuild lfc and run it.

What do you think?

As per 84efdc8, the rebuild feature no longer exists. We added a -r/--run flag to build-lfc instead. This allows one to rebuild and then subsequently run lfc with whatever arguments come after the -r switch.

For instance, build-lfc -r --help will build and then invoke lfc --help.
