The line it complains is std.file.FileException at std\file.d(3713): 
even after enabling debug it points to the same

Output:
D:\DScript>rdmd -debug Test.d -r  dryrun

std.file.FileException at std\file.d(3713): 
N:\PROD_TEAM\TST_BACKUP\abcyf0\TST_BATS\j2ee_backup\cluster\states0\apps\bat.com\tc~bat~agent~application~e2emai~std~collectors\servlet_jsp\tc~bat~agent~application~e2emai~std~collectors\root\WEB-INF\entities\DataCollectionPushFileContentScannerTypeBuilder: The system cannot find the path specified.
