groovy grape verbose

Question

Is there a way to print Ivy output when using Groovy Grape.

when I use Grape, it's just hanging there till finishes downloading all dependencies. I would like to know what it's happening and what it's downloading.

Thanks,

Answer 1

Looks like this might be in Groovy 1.7.6

https://issues.apache.org/jira/browse/GROOVY-4014

i.e. -Dgroovy.grape.report.downloads=true in JAVA_OPTS or on the command line

The download report is useful. It would be better to get true verbose output that includes the repos it's searching – Nuncia

this is nice but only if it reported why it freezes after this line.. Preparing to download artifact javax.servlet#servlet-api;2.4!servlet-api.jar – Spatter

Answer 2

tim_yates answer is good but if you need to debug a problem with Grapes, then this might be useful:

-Divy.message.logger.level=4

Answer 3

For full debugging, you need to use both of these settings exported via JAVA_OPTS when running in a Groovy script.

export JAVA_OPTS='-Divy.message.logger.level=4 -Dgroovy.grape.report.downloads=true'
./myScript.groovy

windows set JAVA_OPTS="-Dgroovy.grape.report.downloads=true -Divy.message.logger.level=4 %JAVA_OPTS%" unix export JAVA_OPTS="-Dgroovy.grape.report.downloads=true -Divy.message.logger.level=4 $JAVA_OPTS"
