Java 运行Linkedin'；李先生就是一个例子

我使用以下链接作为指导：和

• 我下载了Gradle1.4-其余的.li源代码需要1.2或更高版本。运行

  gradle-version

  时，我看到以下内容：

  Gradle 1.4
  
  Gradle build time: Monday, January 28, 2013 3:42:46 AM UTC
  Groovy: 1.8.6
  Ant: Apache Ant(TM) version 1.8.4 compiled on May 22 2012
  Ivy: 2.2.0
  JVM: 1.7.0_09 (Oracle Corporation 23.5-b02)
  OS: Windows 7 6.1 amd64
  

  那部分应该没问题

• 我从中下载了所有源代码并解压缩
• 我根据设置了RESTLI source/rest.li的路径（不确定是否需要这样做-确认无需）
• 我在命令行中导航到

  \rest.li master\example standalone app\api

• 我按照执行了

  gradle构建-stacktrace

  。这给了我以下堆栈跟踪：

  按需创建属性（又称动态属性）已被弃用，并计划在Gradle 2.0中删除。请阅读http://gradle.org/docs/current/dsl/org.gradle.api.plugins.ExtraPropertiesExtension.html 有关替换动态特性的信息，请参见。
  不推荐使用的动态属性：“根项目‘示例独立应用程序’”上的“pegasusVersion”，值：“1.8.3”。
  不推荐使用的动态属性：“根项目‘示例独立应用程序’”上的“spec”，值：“{product={pegasus={dat…”。
  不推荐使用的动态属性：“项目：api”上的“sourceCompatibility”，值：“1.6”。
  在多个位置创建了不推荐使用的动态属性“sourceCompatibility”。

  失败：生成失败，出现异常。
  *出了什么问题：
  任务“：api:GenerateDateTemplate”的执行失败。
  >方法java.net.URLClassLoader#的方法重载不明确。
