Last month I head the idea to only show the -rf option if you ran Maven
with at least the install goal. The next step was to fix this, either with
serialization of the MavenProjects or xml-file which could be picked when
continuing the build with the -rf argument. Hence, why not work on that
second part immediately, which would make the first step unnecessary.
Right now it's still an idea, haven't worked on it yet.
Also: don't underestimate the power of the -amd flag.

I am saying that *if* you _need_ to use "clean install" then your build

not the best it could be and you may have issues with your build that

haven't noticed.
To be fair, a lot of the "install hack" stuff I've seen is more
historical and related to issues in Maven <=2.2.1.
For example:
build a few modules that result in some jars/classes/whatever
build a maven plugin that uses those modules
use that plugin in later modules
That is likely one of the most common "install hack" cases as that never
seemed to work correctly (or at all) without actually installing the
jars and plugins. Honestly, until you mentioned it today, I hadn't
even tested this case with 3.0.4 to see if it's now fixed. Seems like
it is. Time to go update builds. :-)

If you have a big multi-module build and are only working in one small
part, by all means do
$ git pull
$ mvn clean install
$ mvn clean install -pl foo:bar -am (or -amd depending on your needs)
$ mvn clean install -pl foo:bar -am
...
$ mvn clean install -pl foo:bar -am
Just don't assume that you always have to run as far as install... and
make
sure your build doesn't require it also
Just another user trying to do things right,
Best,
Laird
