java FileNotFoundException:[excel在本地计算机上的位置]文件名、目录名或卷标语法不正确

Question

（我已经尝试了stackoverflow上的所有可用答案，但似乎没有任何帮助） 我在Eclipse（Luna）IDE的两个不同项目中编写了两个脚本。此脚本从excel中读取，然后写入。（注意#我在两个项目中都使用了ExcelReadWrite类）两个脚本几乎相同，但只有一个工作正常，另一个脚本抛出异常。 错误日志

Exception in thread "main" java.io.FileNotFoundException: ‪D:\AutomationMobile\Testing.xls (The filename, directory name, or volume label syntax is incorrect)
    at java.io.FileOutputStream.open0(Native Method)
    at java.io.FileOutputStream.open(Unknown Source)
    at java.io.FileOutputStream.<init>(Unknown Source)
    at java.io.FileOutputStream.<init>(Unknown Source)
    at apr_package_mortgage_day4.ExcelReadWrite.save_excel(ExcelReadWrite.java:126)
    at apr_package_mortgage_day4.Driver_Age_apr.main(Driver_Age_apr.java:32)

在上面的错误日志中，我单击了本机方法（超链接），这将打开FileOutputStream。班 其中包含“源未找到源附件不包含文件FileOutputStream.class的源” 我点击了一个按钮——“更改附加源”，打开了一个名为“源附加配置”的向导，上面写着“选择包含rt.JAR源的位置（文件夹、JAR或zip）” 我是Java新手，因此我不知道这里需要做什么。请帮忙
