...
currently,
...
Maven
...
does
...
not
...
require
...
declaration
...
of
...
properties
...
used
...
in
...
the
...
pom,
...
you
...
just
...
use
...
them
...
anywhere
...
you
...
like.
...
Usually,
...
if
...
a
...
property
...
is
...
missing,
...
bad
...
things
...
tend
...
to
...
happen
...
because
...
it
...
is
...
replaced
...
with
...
the
...
string
...
"null".
...
On
...
a
...
good
...
day,
...
resources
...
from
...
"translations-null-null"
...
aren't
...
included
...
in
...
the
...
build,
...
on
...
bad
...
days
...
it's
...
worse...
...
And
...
when
...
you
...
find
...
the
...
missing
...
property
...
in
...
a
...
pom
...
you
...
haven't
...
written,
...
you
...
have
...
to
...
figure
...
out
...
what
...
"${lopt}"
...
means
...
and
...
what
...
its
...
legal
...
values
...
are...
...
So
...
instead
...
typing
...
| No Format |
|---|
<properties> <lopt>en_US</lopt> </properties> {noformat} |
this
...
proposal
...
wants
...
you
...
to
...
write
...
| No Format |
|---|
<properties> <property> <name>lopt</name> <defaultValue>en_US</defaultValue> <required>true</required> <description>Locale to use</description> <options> <option> <value>de_DE</value> <description>Use German locale</description> </option> </options> </property> </properties> {noformat} |
Of
...
course,
...
Maven
...
should
...
display
...
an
...
error
...
if
...
a
...
required
...
variable
...
is
...
missing.
...
And
...
it
...
would
...
be
...
nice
...
to
...
have
...
"help:describe-properties"...
