These commands work well with mono-module too, even if mono-module could permit some optimizations (everything can be run
in only one Maven invocation).
+
+* Avoiding Extra Path During Staging
+
+ When staging the site, sometimes extra directories appear between <<<target/staging>>> and the effective root of the site:
+ this is caused by the auto-detection algorithm of site root, which cannot detect at which level to stop.
+
+ This can be fixed by configuring the {{{/plugins/maven-site-plugin/stage-mojo.html#topSiteURL}site plugin's topSiteURL parameter}}
+ (added in version 3.3) with top distribution management site url in a parent pom:
+
++-----+
+ <distributionManagement>
+ <site>
+ <id>site</id>
+ <url>scm:svn:https://svn.apache.org/repos/asf/maven/sandbox/bimargulies/site-test</url>
+ </site>
+ </distributionManagement>
