Jgrapht: Unable to setup jgrapht with gradle

Hi,

I'm new to both jgrapht and gradle so it is entirely possible that I'm missing something that is absolutely trivial.

I have added this to my build.gradle
compile 'org.jgrapht:jgrapht:0.9.0'

After this I do a gradle build and this is my gradle cache, it seems that it is unable to download the jar for jgrapht.
nikhil ~/.g/c/m/files-2.1> find . | grep '.jar$' ./junit/junit/4.11/28e0ad201304e4a4abf999ca0570b7cffc352c3c/junit-4.11-sources.jar ./junit/junit/4.11/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar ./org.hamcrest/hamcrest-core/1.3/1dc37250fbc78e23a65a67fbbaf71d2e9cbc3c0b/hamcrest-core-1.3-sources.jar ./org.hamcrest/hamcrest-core/1.3/42a25dc3219429f0e5d060061f71acb49bf010a0/hamcrest-core-1.3.jar ./org.slf4j/slf4j-api/1.7.5/654135274d4c27132ea208a4ec07f344bdb83bcb/slf4j-api-1.7.5-sources.jar ./org.slf4j/slf4j-api/1.7.5/6b262da268f8ad9eff941b25503a9198f0a0ac93/slf4j-api-1.7.5.jar

But I can see that the pom has been downloaded

I only have maven central in my sources. Is jgrapht not present there?
If not is there some other source I could add to my build.gradle to get this to work. I don't want to be downloading jars and adding them to the classpath all the time.
