編譯失敗安裝

Question

我想要編譯我的Maven項目和我有這個奇怪的例外。經過Google搜索了很多，但我沒有找到任何東西。 我的JDK是Sun JDK 7，這是我的Maven編譯器插件配置

 <plugin> 

      <artifactId>maven-compiler-plugin</artifactId> 
      <configuration> 
       <compilerArgument>-Xlint:all</compilerArgument> 
       <showWarnings>true</showWarnings> 
       <showDeprecation>true</showDeprecation> 
       <source>1.7</source> 
       <target>1.7</target> 
       <encoding>UTF-8</encoding> 
       <debug>true</debug> 
       <optimize>true</optimize> 
      </configuration> 
     </plugin> 

和異常

你可能已經在編譯器中的錯誤絆倒了。

「請在檢查Bug Parade上的重複項後，在Java開發人員連接（http://java.sun.com/webapps/bugreport）上提交錯誤信息，並在報告中包含您的程序和以下診斷信息，謝謝。

您可能需要更新您的JDK之前的最新版本，雖然。
