Warning the selected directory is not a valid tomcat home

Question

I installed Tomcat with home brew brew install tomcat. On Selecting Tomcat server to add a server to the application server I get this

Warnin

Answer 1

This recently came up for me on Ubuntu 17.04

What worked for me

cd /var/lib/tomcat8
rmdir lib/
ln -s /usr/share/tomcat8/lib/ .
ln -s /usr/share/tomcat8/bin/ .

I'm not sure this is the best fix but it worked for me. For some reason the default install left the tomcat8/lib directory empty while the real libraries are under the share directory.
