Dots in this context work, because pom.repository.url is not a name of a
variable - it is an expression! The original variable is 'pom', then
'repository' property is read from it bean-ways, and then 'url' property
is read from the previous result.
The other thing is why empty() returns false even if the actual value
of the expression is null? I don't know why. I wasn't able to find
any reference of the jexl syntax...

Re: Jelly: ${empty(pom.repository.url)} doesn't work
I've often found it useful to overtest on those kinds of things.
test=${!empty(pom.repository.url == 'true' and
!pom.repository.url.trim().equals('true')}
I discovered that if you set a goal on the command line, as in
-Dgoal
but forget to give it anything (-Dgoal=something)
the variable goal will exist and yet somehow fail the !empty test.
the extra trim().equals('true') business seems to work for that.

RE: Jelly: ${empty(pom.repository.url)} doesn't work
Sorry for incomplete info:
here is the complete path:
maven-xdoc-plugin-XXX/plugin-resources/site.jsl
line :195.
to test, in project.xml you can omit repository completely, or create
a nested empty tag url /
Thank you.

It's in plugin-resources/navigation.jelly.
I haven't checked the behaviour myself, though, so I can't warrant the

Jelly interprets dots.

That's because of line 442 of org.apache.maven.cli.App.java, where it
checks for an '=' in the -D args, and if one's not found, sets the
variable to true.
