gradle idea plugin: libraries marked as "unresolved dependencies"

Question

When trying to run the idea plugin for my gradle project, a number of my intellij libraries are in error with Library: 'gradle: unresolved_dependency_blah_blah' has broken classes path. the library itself is marked as "unresolved dependencies"

My gradle project is a multi module, I have applied the idea plugin to allprojects.

Intellij version is #IU-134.1007

gradle version is 1.11

Any help would be appreciated.

UPDATE: these are an example of some of the dependencies i have:

apply plugin: 'groovy'
dependencies {
 compile 'org.eclipse.jgit:org.eclipse.jgit:3.2.0.201312181205-r'
 compile 'org.codehaus.groovy:groovy:2.2.1'
 testCompile 'org.junit:junit:4.11'
}

all three have the errors

• Peter Niederwieser: You'd have to provide more details, such as which exact dependencies can't be resolved. It could mean that you didn't declare any repositories, misspelled the dependencies, the dependencies don't exist, etc. gradle build would likely fail in such a case.
• coderatchet: I have adjusted the question with my failing examples
• fge: And what if you use gradle from the command line? Does it succeed then?

Answer 1

Solved...

The issue was that i had not declared any repositories. (thank you peter)

adding the following to my root project resolved the dependencies correctly:

allprojects {
 repositories { mavenCentral() }
}
