http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26901 regex with file mapper incorrectly handles ${file.separator} Summary: regex with file mapper incorrectly handles ${file.separator} Product: Ant Version: 1.6.0 Platform: PC OS/Version: Windows XP Status: NEW Severity: Normal Priority: Other Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The documentation for <mapper> states: "Note that Ant will not automatically convert / or \ characters in the to and from attributes to the correct directory separator of your current platform. If you need to specify this separator, use ${file.separator} instead." We are using <mapper type="regex"> to copy a directory structure that looks like this: /Root/ /sub1/ /src/scripts/files.. /sub2/ /src/scripts/files.. /sub3/ /src/scripts/files.. /sub4/ /src/scripts/files.. to this: /NewRoot/ /sub1/ /files.. /sub2/ /files.. /sub3/ /files.. /sub4/ /files.. To do it we are using <mapper> with <copy> like this: <copy todir="NewRoot"> <mapper type="regexp" from="(.*?).src.scripts.(.*)" to="\1${file.separator}\2"/> <fileset dir="Root"> <include name="**/src/scripts/*"/> </fileset> </copy> The problem happens with the ${file.separator}, we expect the results as stated above, what we are actually getting is this: /NewRoot/ /sub1/ /2 /sub2/ /2 /sub3/ /2 /sub4/ /2 (the 2's are files) If we modify the mapper's "to" regex to this: to="\1${file.separator}${file.separator}\2" The results are what we expect. I believe the problem lies in the handling of regular expressions and how ant is using substitution. We are on a windows machine, so the "to" regex (in the buggy case) will resolve to something like this before sending the regular expression off to Java (using the standard Reg ex handling with Java 1.4): sub1\\2 Java then interprets the 2 "\"s to be a literal "\" and ant is then left to map everything to the filename "2". Let me know if you need more information. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
