Gradle 1.12 mentions needed jar but does not download it nor put it onto the CLASSPATH

Hate to post a question for such an ancient version of Gradle, but upgrading is on the pile of tech debt over there ==>

We use a plugin to provide build functionality adapted from our Ant/Ivy builds. Part of what the plugin does is resolve and publish artifacts. We recently migrated from an on-prem version of Artifactory to a SaaS version, which requires credentials. As such, the plugin was modified for the new URL and credentials. The project.repositories block addresses two repos, one for our locally-generated artifacts (ivy), the other for 3rd party jars (maven). It looks like this:

            project.repositories {
                    ivy {
                            name "gid-only"
                            url "${artifactoryURL}/gid-only"
                            layout "pattern", {
                                    ivy "[organization]/[module]/ivy-[revision].xml"
                                    ivy "[organization]/[module]/[revision]/ivy.xml"
                                    artifact "[organisation]/[module]/[revision]/[type]/[artifact]-[revision].[ext]"
                                    artifact "[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"
                                    artifact "[organisation]/[module]/[revision]/[organisation]-[artifact]-[revision].[ext]"
                            }
                            credentials {
                                    username System.getenv("ARTIFACTORY_USERNAME")
                                    password System.getenv("ARTIFACTORY_PASSWORD")
                            }

                    }
                    maven {
                            name "maven-repos"
                            url "${artifactoryURL}/maven-repos"
                            credentials {
                                    username System.getenv("ARTIFACTORY_USERNAME") 
                                    password System.getenv("ARTIFACTORY_PASSWORD") 
                            }
                    }

When I run a build with this configuration, the debug log mentions a a needed jar several times:

However, it never downloads the jar and puts it onto the CLASSPATH, resulting in a compilation error.

The dependency declaration looks like this:

[ group: ‘com.google.guava’, name: ‘guava’, version: “15.0”, configuration: ‘compile(*)’],

If I change the “configuration” declaration to ", configuration ‘*’, it does download the jar and adds it to the CLASSPATH. The problem is, this used to work prior to the SaaS migration, and I have literally hundreds of build.gradle files that would need to be modified as such if I take that approach. I would prefer not to do that but, rather, get it working by modifying the plugin as necessary.

Thanks for any advice anyone can render!
