Substitution
...
of
...
Custom
...
Maven
...
Components
...
We're
...
already
...
starting
...
to
...
see
...
an
...
emerging
...
need
...
to
...
customize
...
Maven,
...
by
...
adding
...
new
...
types
...
of
...
artifact
...
resolvers,
...
project
...
builders,
...
etc.
...
Since
...
we've
...
taken
...
so
...
much
...
care
...
to
...
design
...
Maven
...
as
...
component-oriented
...
software,
...
we
...
need
...
to
...
open
...
up
...
those
...
component-oriented
...
aspects.
...
State
...
of
...
the
...
Art
...
Currently,
...
if
...
a
...
user
...
wants
...
to
...
add
...
a
...
custom
...
artifact
...
handler
...
to
...
Maven,
...
the
...
cleanest
...
way
...
to
...
do
...
it
...
is
...
to
...
write
...
the
...
resolver
...
along
...
with
...
a
...
new
...
components.xml.
...
This
...
components.xml
...
must
...
define
...
a
...
new
...
component
...
descriptor
...
that
...
overrides
...
the
...
default
...
one.
...
After
...
that,
...
the
...
user
...
will
...
have
...
to
...
stash
...
this
...
resolver
...
jar
...
into
...
a
...
new
...
directory,
...
most
...
likely
...
under
...
someplace
...
like
...
${maven.home}/custom.
...
Finally,
...
they
...
have
...
to
...
add
...
a
...
new
...
line
...
to
...
the
...
${maven.home}/bin/m2.conf
...
file,
...
to
...
add
...
the
...
new
...
directory
...
to
...
the
...
front
...
of
...
the
...
classpath,
...
like
...
this:
| Code Block |
|---|
} load ${maven.home}/custom/*.jar <-- this one has to come first, to override. load ${maven.home}/lib/*.jar {code} h3. Where can we go from here? It would be *much* nicer to have the ability to simply dump the new resolver jar into |
Where can we go from here?
It would be much nicer to have the ability to simply dump the new resolver jar into ${maven.home}/lib,
...
and
...
change
...
the
...
selection
...
priority
...
for
...
the
...
ArtifactResolver
...
to
...
use
...
the
...
new
...
implementation
...
instead
...
of
...
the
...
default
...
one...this
...
would
...
happen
...
in
...
a
...
master
...
config
...
XML
...
file,
...
maybe.
...
It
...
would
...
also
...
allow
...
the
...
new
...
resolver
...
to
...
delegate
...
to
...
the
...
default
...
implementation
...
without
...
redefining
...
it's
...
descriptor
...
(right
...
now,
...
we'd
...
be
...
overriding
...
the
...
default
...
implementation's
...
component
...
descriptor,
...
effectively
...
wiping
...
it
...
out
...
of
...
the
...
container).
