在eclipse中，不小心点击删除后，再导入工程时老是提示错误：Failed to read the project description file (.project) for Bluetooth. The file has been changed on disk, and it now contains invalid information. The project will not function properly until the description file is restored to a valid state.
解决办法，将工程从workspace中备份，并删除workspace中的工程文件，再重新导入，成功
，你的内心会被洗成一片空白，自由而宁静，
