“在osx上构建WALA”；无法解析导入java.lang.invoke“；

我试图在OSX上编译WALA，但遇到了一个令人困惑的错误，即它找不到java.lang.invoke.CallSite。奇怪的是，我可以编写一个简单的项目，导入java.lang.invoke.*并用javac很好地编译它

谢谢你的帮助

`java 7中引入了

java.lang.invoke

包。正如您的

mvn版本

命令所示，Maven正在使用java 6：

Java version: 1.6.0_65, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

---

您需要将Maven配置为使用Java 7。

谢谢。我可能应该指出一个绊脚石，以防其他人遇到相同的问题，在链接的文章中，它在路径名周围显示了一个“环绕，它应该是”。不过，这可能只是一个奇怪的html格式问题。谢谢。我可能应该指出一个绊脚石如果其他人遇到同样的问题，在链接的文章中，它会在路径名周围显示一个“环绕，它应该是”。也许这只是一个奇怪的html格式问题。
