安卓构建系统Gradle

Question

我正在测试仍处于Beta版的Android新构建系统。我已经实现了一些代码，但是出现了以下错误：

No such property: resolutionResult for class: org.gradle.api.internal.artifacts.ivyservice.ErrorHandlingArtifactDependencyResolver$ErrorHandlingResolvedConfiguration

build.gradle

buildscript {
  repositories {
      mavenCentral()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:0.2'
  }
}
apply plugin: 'android'

android {
  sourceSets {
      main {
          manifest {
              srcFile 'AndroidManifest.xml'
          }
          java {
              srcDir 'src'
          }
          res {
              srcDir 'res'
          }
          assets {
              srcDir 'assets'
          }
          resources {
              srcDir 'src'
          }
      }
  }
}

我也试过示例，但出现了相同的错误。问题出在哪里？

你能发布完整的堆栈跟踪吗？我猜测你正在错误的Gradle版本上运行它（也许是早期或预览版本？）这是在配置解析期间引发的内部错误，因此可能是Android插件试图访问Gradle属性，而该属性不存在于你的Gradle安装中。gradle -v显示什么？ - mxk

在回答中添加了完整的堆栈跟踪和Gradle版本。 - endian

Android插件是为Gradle 1.2构建的。尝试降级您的Gradle安装程序，看看是否有帮助。 - mxk

我走了几步，但在构建应用程序时又出现了另一个异常。请参见编辑后的帖子以获取更多信息。 - endian

你必须将“target”属性设置为你的应用所针对的平台版本。你是否遵循了http://tools.android.com/tech-docs/new-build-system/using-the-new-build-system？ - mxk

Answer 1

版本0.2是使用Gradle 1.2（1.3尚未发布）开发的。我们知道目前正在使用一些内部内容，因此在1.3上可能会出现问题（尚未测试，即将进行测试）。

目前，请使用Gradle 1.2。

- Xavier Ducrohet

---

快速更新，我们已经修复了问题，因此下一个更新将可与1.3一起使用（实际上，它将需要1.3，并且我们已经放置了检查以确保使用正确的版本）。 - Xavier Ducrohet

这真的是我们的错。我们正在使用一个孵化特性。下一个版本将在1.3 / 1.4上运行（我们正在两个版本上进行测试）。 - Xavier Ducrohet

0.3仍在开发中，需要一个尚未发布的平台工具版本。 - Xavier Ducrohet

@Xav 我在0.3和1.3版本中遇到了这个问题，它抱怨目标不能为空...稍后会发布SO问题。 - Jimmy

目标已更名为compileSdkVersion。请确保阅读新文档。 - Xavier Ducrohet

Answer 2

您需要在gradle.build文件中添加compliedSdkVersion 17：
