Gradle找不到参数的方法XYZ

Question

gradle和groovy有点新事物，试图使用以下任务：http：//bmuschko.github.io/gradle-docker-docker-plugin/docs/groovydoc/grovydoc/com/bmuschko/gradle/gradle/gradle-/docker/tasks/image/dockerpushimage.html

作为folows：

task pushImageDev(type: DockerPushImage) {
    imageName "xxxxxx:5000/${project.name}-${appEnviroment}:${version}"
    registryCredentials {
        email = '[e-mail]'
        url = 'xxxxxx:5000'
        username =  'xxxxxx'
        password =  'xxxxxx'
    }
}

，但我一直得到...

Could not find method registryCredentials() for arguments [build_21ymvy7kfomjn3daqwpuika10$_run_closure8$_closure18@dd69c19] on task ':pushImageDev' of type com.bmuschko.gradle.docker.tasks.image.DockerPushImage

我相信您只能在docker任务配置中使用registryCredentials方法，而不是在自定义任务中，例如

docker {
    registryCredentials {
        url = 'https://gcr.io'
        username = '_json_key'
        password = file('keyfile.json").text
    }
}

如果要创建一个自定义任务，则可能必须创建一个dockerregistrycredentials的实际实例，例如

task pushImageDev(type: DockerPushImage) {
    imageName "xxxxxx:5000/${project.name}-${appEnviroment}:${version}"
    registryCredentials(new DockerRegistryCredentials(...));
}

原因是 registryCredentials {...}是dockerextension.groovy中定义的扩展名，它不适用于自定义任务。它不是类registryCredentials的固定器DockerPushImage。

也有效的是嵌套注册表凭据调用docker在自定义任务中，尽管我不确定为什么：

task pushImageDev(type: DockerPushImage) {
    appEnviroment = 'dev'
    imageName "xxxxxx/${project.name}-${appEnviroment}:${version}"
    docker {
        registryCredentials {
            username = "${nexusUsername}"
            password = "${nexusPassword}"
        }
    }
}
