我正在尝试在我的机器上构建spring-data-commons：
我做了以下事情：
$ git clone --depth 1 https://github.com/spring-projects/spring-data-commons.git
$ cd spring-data-commons
$ mvn clean install
我得到了：
[ERROR] COMPILATION ERROR :

此外，我可以在我的jdk中找到方法java.util.Date.toInstant。
更新
这是mvn clean install -X输出的一部分：
这是否与下面的代码段中的-target 1.6 -source 1.6有关？
