Gradle 脚本无法解析 Artifactory

Question

我正在使用 Gradle 访问 Artifactory。 Artifactory 具有特定的依赖关系，但不知何故 gradle 无法向 Artifactory 发送任何请求。即使我尝试清理缓存并运行 gradle build 命令来获取文件。但我没有取得任何成功。通过gradle.build文件如下。

buildscript {
    repositories {
        maven { url 'http://repo.jfrog.org/artifactory/gradle-plugins' }
    }
    dependencies {
        classpath(group: 'org.jfrog.buildinfo', name: 'build-info-extractor-gradle', version: '2.0.12')
    }
}

apply plugin: 'maven'
apply plugin: 'artifactory'
apply plugin: 'java'

repositories {
    maven {
      url 'http://artifactory/repo'
    } 
}

group = 'com.locationlabs'
version = '1.1'

artifacts {
   archives file("${project.name}-${project.version}-jstest.txt")

}

artifactory {
    contextUrl = 'http://artifactory'
    publish {
       repository {
          repoKey = 'autotest' 
          username = 'rakesh.kumar'  
          password = 'password'
       }
       defaults {
          publishBuildInfo = true
          publishArtifacts = true
          publishPom = true
          publishIvy = false
       }
    }
}

artifactoryPublish {
   publishConfigs('archives')
}

dependencies {
  compile group: 'com.locationlabs', name: 'gradletest', version: '1.0', classifier: 'jstest', ext: 'txt'
 }

每当我运行 gradle 脚本时，它都会失败并出现以下异常和堆栈跟踪。

一件非常奇怪的事情是，相同的脚本文件在另一台计算机上可以工作，但在我的计算机上却不起作用，即使另一台计算机具有相同的配置和设置。

我尝试在互联网上搜索但无法获得任何帮助。在此非常感谢任何形式的帮助。

Answer 1

昨天，在尝试更改 gradle.settings 中的项目名称(rootProject.name = 'something')后，我看到了完全相同的 NPE。当我从 gradle.settings 中删除这一行时，异常消失了。

经过一番调查并在 http://forums.gradle.org/gradle/topics/how_to_get_the_latest_integration_version_number 的帮助下我终于发现原因是一种循环依赖，当我的项目依赖于某个模块时，该模块又反过来依赖于与“当前”项目具有相同组和项目名称的模块。

这可能是你的情况吗？您的项目名称是什么？而gradletest的依赖是什么？请检查您引用的 gradletest 模块是否不依赖于您的项目。或者，如果您的项目本身名为 gradletest，那肯定可以解释该错误。
