what command line options did you use?
Btw there is already 3.0.0.Final released
sudo docker run -it -v /var/lib/docker/data:/var/lib/docker/data:rw jboss/windup /opt/jboss/windup/bin/windup --input /var/lib/docker/data/jee-example-app-1.0.0.ear --output /var/lib/docker/data/windupreport --target eap6
This is the command used.
But only this version is available in the client system. Requested for the 3.0.0,but did not get the approvals yet.
This worked for me:
docker run -it -v /path/to/samples/:/var/lib/docker/data:rw jboss/windup:2.4.0.Final_jdk7 /opt/jboss/windup/bin/windup --input /var/lib/docker/data/jee-example-app-1.0.0.ear --target eap6
Is it possible that the rulesets have been updated to a newer version than 2.4.0 can support?
