issue in installing extension to knime-executor

Hi there,

I was installing an extension Vernalis, but I’m facing some issues doing that.

I entered the command shown below,

./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r 'http://update.knime.com/community-contributions/trusted/4.6' \
> -i com.vernalis.knime.feature.feature.group \
> -d /opt/knime/knime-executor

and I’m getting output:

Please help me with this!
