NullPointerexception while runnig windup tool

[sbyapaneni]

I am using windup 2.4.0 version. When I try to run the tool getting the below exception.

WARNING: No packages were set in --packages. This will cause all .jar files to be decompiled and can possibly take a long time. Check the Windup User Guide for performance tips.

Writing graph config to /tmp/windupgraph_PMVgXC/TitanConfiguration.properties

Windup execution failed due to: null

Please help me to resolve the issue.

what command line options did you use?

Btw there is already 3.0.0.Final released

[sbyapaneni]

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?
