For my example, I have 2 artifacts that I depend on for compile and I am using gradle 1.5. Both artifacts are stored in our Artifactory server but only artifactA has a POM, artifactB does not.

build.gradle

dependencies {
compile(group: 'com.test', name: 'artifactA', version: '3.18.2.+')
compile(group: 'com.test', name: 'artifactB', version: '3.18.2.+')
}

task dumpResolved << {
def arts = project.configurations.compile.resolvedConfiguration.resolvedArtifacts
arts.each { println "${it.moduleVersion.id.group}, ${it.moduleVersion.id.module.name}, ${it.moduleVersion.id.version}" }
}

Now, when I display dependencies, only the artifact with the POM, artifactA, displays the resolved version number:

$ ./gradlew dependencies
compile - Classpath for compiling the main sources.
--- com.test:artifactA:3.18.2. -> 3.18.2.0.999
--- com.test:artifactB:3.18.2.+

Similarly, my dumpResolved task only shows the fully resolved version number for artifactA:

$ ./gradlew dumpResolved
:dumpResolved
com.test, artifactA, 3.18.2.0.999
com.test, artifactB, 3.18.2.+

Why the difference in behaviour? Is there a way to make my dumpResolved task work without POMs?
