Test fails with StackOverflowError

[prestontim]

I'm attempting to write a Spock test that's verifying a custom 'artifactory.license' property that I'm setting on the artifactoryPublish task. The problem is that every time I try to access the task.properties property, the test throws a StackOverflowError.

The entirety of my test case is below. Can somebody please tell me what I'm doing wrong here? (I am currently using org.jfrog.buildinfo:build-info-extractor-gradle:4.4.0.)

import org.gradle.api.Project
import org.gradle.testfixtures.ProjectBuilder
import spock.lang.Specification

public class ArtifactoryTest extends Specification {
    def "project has license property set on artifactoryPublish task"() {
        given: "a test project"
        Project proj = ProjectBuilder.builder().build()
        proj.version = '1.0-SNAPSHOT'
        proj.group = 'com.demo'
        proj.description = 'Test case'

        when: "the plugin is applied"
        proj.apply(plugin: 'com.jfrog.artifactory')
        proj.artifactoryPublish {
            properties = ['artifactory.licenses': 'foo-bar-license']
        }
        proj.evaluate()

        then: "the project has the license property set"
        def task = proj.tasks.getByName("artifactoryPublish")
        task.properties.get('artifactory.licenses') == 'foo-bar-license'
    }
}
