Gradle-获取MavenDeployer URL

Question

我当前正在尝试在任务中获取Maven Deployer的URL，但是失败了。 我可以获取Maven Deployer本身，但是在调用方法mavenDeployer.getRepository()时，显然无法创建RemoteRepository类型的对象。

这是build.gradle文件：

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "file:///path/to/maven/repo/")
        }
    }
}

在我的任务中：

Upload uploadArchives = project.getTasks().withType(Upload.class)
                          .findByName(BasePlugin.UPLOAD_ARCHIVES_TASK_NAME);

for(ArtifactRepository repo : uploadArchives.getRepositories()) {
    if (repo instanceof MavenDeployer) {
        MavenDeployer mavenDeployer = (MavenDeployer) repo;
        System.out.println(repo) //Returns org.apache.maven.artifact.ant.RemoteRepository

        RemoteRepository l = (RemoteRepository) mavenDeployer.getRepository() // Crashes here
    }
}

它显示：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':myTask'.
> org/apache/maven/artifact/ant/RemoteRepository

stacktrace结尾于：

Caused by: java.lang.ClassNotFoundException: org.apache.maven.artifact.ant.RemoteRepository

显然，即使我成功导入了Gradle，也无法找到org.apache.maven.artifact.ant.RemoteRepository类。 如果我注释掉创建类MavenDeployer ，则它可以正常工作。

有没有办法解决这个问题？ 如果不是，是否还有另一种方法来获取Maven Deployer的存储库URL？

构建脚本类加载器不会公开RemoteRepository。 但是您应该能够解决这些信息，感谢您使用groovys ducktyping：

task printDeployerUrl << {
    tasks.withType(Upload) { uploadTask ->
        for(ArtifactRepository repo : uploadArchives.getRepositories()) {
            if (repo instanceof MavenDeployer) {
                MavenDeployer mavenDeployer = (MavenDeployer) repo;
                System.out.println(repo.repository.url)
            }
        }
    }
}
