yes, it is expected behaviour: see "inheritance assembly" step of model
builder [1]
in your case, your config cause artifactId to be added twice: one on
project.url and one on site.url before ${project.url} is interpolated
You should just not use ${project.url} in distributionManagement/site: that's
what is causing you the issue
Notice: this strategy (adding artifactId) was perfect for a good number of
years, when sites were deployed to filesystems: with sites deployed to git, it
is known that it does not fit this case, and you're not the first to complain
(without really understanding why "it does not work as expected" on your case:
the important part here is *on your case*, because this git case is what cause
some new requirements that did not exist before)
I have prepared a new feature for (future) Maven 3.4.0 in MNG-5951 [2]
This will give attributes to disable artifactId addition on fields that have
this url inheritance feature
