Gradle unnable to resolve archiva dependencies

Question

I have looked at the answer here, but it did not quite apply: Gradle Not Resolving Maven Repo on localhost

basically, I have a trivial gradle project and corresponding build.gradle:

apply plugin: 'maven'
apply plugin: 'java'

repositories {
  mavenRepo (
    name: 'Snapfish Repo',
    url: 'op2-ivy1.hpd5.aus1.snapfish.com:40000/archiva/repository/snapfish/'
  )
  // mavenCentral()
}

dependencies {
  compile group:'org.slf4j', name: 'slf4j-api', version: '1.6.6'
}

when I run

gradle dependencies

I get the following output:

compile - Classpath for compiling the main sources.
No dependencies
:dependencies FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':dependencies'.
> Could not resolve all dependencies for configuration ':compile'.
   > Could not resolve group:org.slf4j, module:slf4j-api, version:1.6.6.
     Required by:
         :junk:unspecified
      > Target host must not be null, or set in parameters.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

If I use mavenCental(), it works correctly. The relevant debug output is this:

I cannot see why gradle does not work against archiva. In our network, the link op2-ivy1.hpd5.aus1.snapfish.com:40000/archiva/repository/snapfish/org/slf4j/slf4j-api/1.6.6/slf4j-api-1.6.6.pom retrieves the POM. What am I doing wrong? Any help would be appreciated.

Try adding http:// at the beginning of your URL:

url: 'http://op2-ivy1.hpd5.aus1.snapfish.com:40000/archiva/repository/snapfish/'
