大佬教程小编现在分享给大家，也给大家做个参考。

//----------------------------------------------------------------------------------
println new File('/doesnotexist').exists()  // => false
println new File('/doesnotexist').delete()  // => false

new File('/createme') << 'Hi there'
println new File('/createme').exists()  // => true
println new File('/createme').delete()  // => true

names = ['file1','file2','file3']
files = names.collect{ new File(it) }
// create 2 of the files
files[0..1].each{ f -> f << f.name }

def deleteFiles(files) {
    def problemFil@R_197_8371@s = []
    files.each{ f ->
        if (!f.delete())
            problemFil@R_197_8371@s += f.name
    }
    def delCnt = files.size() - problemFil@R_197_8371@s.size()
    println "successfully deleted $delCnt of ${files.size()} file(s)"
    if (problemFil@R_197_8371@s)
        println "Problems file(s): " + problemFil@R_197_8371@s.join(',')
}

deleteFiles(files)
// =>
// successfully deleted 2 of 3 file(s)
// Problems file(s): file3

// we can also set files for deletion on exit
tempFile = new File('/xxx')
assert !tempFile.exists()
tempFile << 'junk'
assert tempFile.exists()
tempFile.deleteOnExit()
assert tempFile.exists()
// To confirm this is working,run these steps multiple times in a row.

// Discussion:
// Be careful with deleteOnExit() as there is no way to cancel it.
// There are also mechanisms specifically for creaTing unqiuely named temp files.
// On completion of JSR 203,there will be additional methods available for
// deleting which throw exceptions with detailed error messages rather than
// just return Booleans.
