My walkmod.xml 

<!DOCTYPE walkmod PUBLIC "-//WALKMOD//DTD" "http://www.walkmod.com/dtd/walkmod-1.1.dtd">
<walkmod>
    <transformation type="imports-cleaner"/>
</walkmod>

I am running the command : walkmod apply

I'm getting a similar error.

For me, I believe it's caused by not being able to resolve an artifact: org.gradle#gradle-tooling-api;2.10

org.walkmod.conf.ConfigurationException: Ivy can not resolve the artifacts. Cause: unresolved dependency: org.gradle#gradle-tooling-api;2.10: not found
