Confluence docs: adding info about how to recognize a maven/tomcat user permission error

Opened this issue · 0 comments

https://wiki.lyrasis.org/display/VIVODOC114x/Installing+VIVO

has a "Permissions" section stating:
The maven user has write permission to the Tomcat webapps directory. Maven will fail silently if it cannot copy files to tomcat.

(if my understanding of maven installing vivo is correct)
Can the wiki be amended to state:
Adding your linux user to the 'tomcat' group is one solution.
This silent failure can be observed by mvn install failing to create a folder at /webapps/vivo.
(Your is set in installer/example-settings.xml)

As a non-Java programmer, I wouldn't expect a full education on Java within the doc. But a practical hint like this would be very useful.
