Hi,
Could you enable stack trace in your console please ?

codenvy> stack-traces-print
Printing of stacktraces set to true

and then reproduce your step please ?

[paulvi]

similar to #102

stack-traces-print also gives NullPointerException

Could you print the Java version that you're using ?

[paulvi]

E:\Codenvy\cli>java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

Thanks Paul

FYI the master branch is now including Karaf version 3.0.2 which is now compliant to JDK 8

Could you try to use cli on the master branch please ?
If you don't want to recompile you may use binaries from Nexus repository:
http://maven.codenvycorp.com/content/repositories/public/com/codenvy/cli/cli-assembly/2.2.0-SNAPSHOT/

similar to #103 was Java 8 issue
