I have added a parent pom file with an URL to our company logo. This
worked fine and the company logo appeared on the right side of the
header section.
I then was looking in changing the default build configuration by
enabling the component
org.apache.maven.continuum.configuration.ConfigurationService in the
file WEB-INF/classes/META-INF/plexus/application.xml and changing the
default-m2-goals value.
After restarting I now get a NullPointerException locate in the header
section that seems to come from the logo configuration I did.
Everything else works fine except that if I click on Appearance I get
again the NullPointerException.
How can I fix this?
