It is indirectly referenced from required .class files(導入項目報錯原因與解決方法)

http://blog.csdn.net/hello_yz/article/details/40113213

The project was not built since its build path is incomplete.The type Java.util.Arrays cannot be resolved. It is indirectly referenced from required .class files.

顯然不是代碼的問題，都木有找到util包下的內容，就很容易想到是jdk版本問題啦！

通常來說，你應該安裝了幾個版本的jdk。

 

做個解決方法的筆記：

1.進入windows\preferences\java\Installed JREs

  add--->Standard VM --->next--->接下來就是選擇JRE home，選擇另一個jdk安裝目錄

2.選中報錯的項目，右鍵，properties\Java Build Path

 add library-->JRE System Library -->next -->workspace default JRE--->finish

刷新項目，已經OK啦！
