http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17154 concat task: if destination file is used as source infinite looping occurs Summary: concat task: if destination file is used as source infinite looping occurs Product: Ant Version: 1.5.1 Platform: PC OS/Version: Other Status: NEW Severity: Minor Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I want to prepend the current changes to my changes file: <target name = "Produce changes file"> <concat destfile = "Temp.changes" append = "true"> <filelist dir = "${basedir}" files = "CurrentChanges, Temp.changes"/> </concat> </target> Ant output: Produce changes file: [concat] Temp.changes: input file is output file. Result: infinite loop, which prepends the contents of "CurrentChanges" over and over again. Expected: stop after one loop iteration (because detection of unusual state seems to take place already) I know this problem can be circumvented by writing to a temporary file and moving it afterwards.
