Hi,
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
<properties>
<lopt>en_US</lopt>
</properties>
this proposal wants you to write
<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>
Of course, Maven should display an error if a required variable is
missing. And it would be nice to have "help:describe-properties"...
Regards,
Jochen
