我尝试按照github上Spring OAuth项目的"入门"部分安装并运行示例：https://github.com/spring-projects/spring-security-oauth.我尝试了不同的方法，在maven测试阶段运行mvn install -P bootstrap 时总是遇到相同的错误
以下是我尝试过的一些变体：
- 已使用Eclipse egit下载v.2.0.9-SNAPSHOT
- 已更改为带标签的v2.0.8版本
- 已更改为带标签的v2.0.7版本
- 已更改为带标签的v2.0.6版本
- 已从master下载2.0.9-SNAPSHOT作为zip
- 下载了2.0.8版本的zip
- 清除了本地maven存储库（实际上在maven-settings.xml中引用了一个空白的dir）
- 用于不同的maven版本（3.0.5和3.3.3）
- 使用了三个不同的JDK
测试阶段的结果总是这样：

由于显然没有其他人遇到这种行为，我一定做错了什么，但我不知道可能是什么
希望得到帮助，比约恩
我认为这实际上是操作系统上嵌入式Redis的问题。我们试图在Spring Session中利用嵌入式Redis，但它给各种操作系统带来了许多问题。参见春季会议/问题/121
简而言之，我认为这是测试中的一个错误。
