Re: [m2e-dev] Providing alternative "root dependencies" for the project 
From what I remember, maven core APIs require actual file name to read,
i.e. explicit 'pom.xml' for regular maven projects. Is polyglot smart
enough to intercept/redirect requests to read pom.xml or would m2e need
to be explicit about pom.clj?

    Take a look at this for ideas:

    https://github.com/sonatype/polyglot-maven

    Specifically the Clojure work:

    https://github.com/sonatype/polyglot-maven/tree/master/pmaven-clojure

    What you want is probably already implemented on the Maven side.



Hello Jason, thanks for the links.
I'll look at them again, but I was already aware of these. So maybe I
don't understand what you're implying.

To restate my problem more briefly : is it possible to have m2e work
with something else than a pom.xml file for loading the pom in memory
? Can I replace the loading of the pom in memory with my own
"strategy" in m2e ?



That is what you would use to use a pom.clj to create a
org.apache.maven.model.Model. m2e uses Maven's internals to load models.
To load any source into an org.apache.maven.model.Model you would create
a ModelReader and there's an example exists:

https://github.com/sonatype/polyglot-maven/tree/master/pmaven-clojure/src/main/java/org/sonatype/maven/polyglot/clojure

The ModelReader and ModelWriter are the place the start.

m2e works with Models internally, but there are no editing facilities
for anything other than a pom.xml files and some changes would have to
be made in m2e to make this work generally. There's no facility to
incorporate models coming from alternate sources at the moment.

    Hello,

    Is it possible to extend/reuse m2e so that root project
    dependencies could be provided by an extension of mine ?

    I'm thinking of the best way to reuse m2e from not a pom.xml
    file, but from a leiningent's project.clj file.

    Granted, some features of m2e will make no sense (esp. the pom
    editors, the maven goal launchers), but all the machinery which
    is only driven from the contents of pom.xml in their AST form
    could potentially be reused if I'm able to load from not a
    pom.xml file, but a project.clj file, no ?

    I've searched through the existing "*maven" extension points,
    without success, so far.

    I know I could go ahead with just using Aether for my own feature
    independent of m2e, but in the end I would en up rewriting lots
    of supporting code e.g. in the GUI area, for user options (one
    example among others: support for user configurable "force check
    of remote repositories for SNAPSHOT deps" option, etc.).


    I am asking here if you think it is a reasonable expectation for
    me to think what I want to achieve is feasible ; and if so, if
    you could help me start by givin me some advices.

    Thanks in advance,

People develop abstractions by generalizing from concrete examples.
Every attempt to determine the correct abstraction on paper without
actually developing a running system is doomed to failure. No one
is that smart. A framework is a resuable design, so you develop it by
looking at the things it is supposed to be a design of. The more examples
you look at, the more general your framework will be.
