Re: [m2e-users] Understanding the Maven Project Builder 
I am not sure <execute> mapping is a good idea in your case. At least
set runOnIncremental=false to only run it after clean build.

There are couple of bugs in m2e bugzilla that talk about Maven console
oddities, but nobody cared enough to provide a patch

Ah, yes, I've looked at that wiki page many times, but I guess its words
and my experience have steered me strongly enough away from ever doing
<action><execute/></action> that I forgot to just try that.  I just did
that and it seems to do what I want.

As far as the background on the m2e builder, I guess I feel like it
could help some.  For example, v1.1 lacks some options that show up in
the v0.12 "Maven/Lifecycle Mapping" dialog in the project properties (in
particular related to what goals get built as a result of "clean"s or
resource changes).  What can/should I infer from that?  Also, in v0.12,
the "Maven Console" window shows me a lot of stuff that I assume is
telling me what the m2e builder is doing (or at least that it's doing
something).  In contrast, the v1.1 "Maven Console" window never seems to
have anything in it.  So I don't ever have a sense of when it's doing
something and what it's doing.

Thanks for your help.

    In short, antrun-plugin is not supported by m2e (and never was, btw).
    You need to reimplement properties file generation logic in
    eclipse-friendly manner. I assume you already saw m2e wiki on the
    subject [1], but have a read if you did not. I can provide more detailed
    explanation of how m2e builder actually works, but this is more a
    developer subject, so let me know on m2e-dev if you want to know
    nitty-gritty of it.

        I'm attempting to convert a large and complex multi-module project
        environment from m2eclipse (v0.12) to m2e (v1.1).  I have things
        pretty
        much working well but things are getting messed up by what I
        assume are
        differences between the way the Maven Project Builder works in
        v0.12 vs.
        v1.1.  In particular, one of my projects uses the
        /maven-antrun-plugin/ to do some stuff the net effect of which is to
        leave some Java properties files somewhere deep under
        /target/classes/.

           The problem arises in cases where the Eclipse "clean" operation
        occurs.  In v0.12 this seems to be OK because it looks like the the
        Maven Project Builder does enough of a “real” Maven build to
        recreate
        those files.  In contrast, in v1.1, well, I don’t know quite
        what the
        m2e Maven Project Builder does, but in any case I’ve configured
        m2e to
        ignore the /maven-antrun-plugin/ (which I need to do to make m2e not

        complain) so the Java properties file doesn’t get recreated and the
        launch of my application fails because those files are required.
          I can
        go back and do a Maven command line build, which fixes things
        until the
        next Eclipse "clean".  Not pretty.

        Any suggestions for a good way of dealing with this situation?  Any
        general background on the behavior of the Maven Project Builder
        would be
        helpful too/instead.

        Thanks.
