我下载了 gradle 1.4 - rest.li 源需要 1.2 或更高版本1。运行时，
gradle -version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所以那部分应该没问题。
- 我从2下载了所有资源并解压缩。
- 我
RESTLI_HOME=/path-to-restli-source/rest.li按1设置（不确定我是否需要这样做 - 确认不需要）。 <my path>\rest.li-master\example-standalone-app\api我在命令行中导航到。我
gradle build -stacktrace按照3执行。这给了我以下堆栈跟踪：Creating properties on demand (a.k.a. dynamic properties) has been deprecated and is scheduled to be removed in Gradle 2.0.
