I don’t know. What is a “gradle cache”? Is that related to #50? For the best results you need to use the maven local cache I think so that you actually generate a pom.xml, but if you are a gradle expert you might know a better way. Please open another issue if you have any ideas (PR more than welcome).

I found the problem is my build.gradle removed this line: apply plugin: ‘io.spring.dependency-management’ that caused thinResolve task not download dependencies

Another problem is thinResolve not use gradle caches but use maven local repo, how can I use gradle caches?
