You know that the filename will be after the 7th field,
so you could do something like this:

Code:
gawk --posix 'NR > 2 && !/\/$/ {
  sub(/([^ \t]+[ \t]+){7}/,"")
  print
  }' infile

Which produces:

Code:
zsh-4.3.10[t]% cat infile
sms_snath_hp_C/CORE BUILD PREREQUISITE:
total 1556
drwxrwxrwx 2 sn sn 4096 2008-06-27 08:31 ./
drwxrwxrwx 13 sn sn 4096 2009-07-22 14:48 ../
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file    name with      eight spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*
zsh-4.3.10[t]% gawk --posix 'NR > 2 && !/\/$/ {
  sub(/([^ \t]+[ \t]+){7}/,"")
  print
  }' infile
This is a file name with seven spaces.jar*
This is a file    name with      eight spaces.jar*
ibmjcefw.jar*
ibmjceprovider.jar*

If you don't want to modify the current record you can save it in a variable and then manipulate the saved record:

Code:
gawk --posix 'END {
  # print the filenames
  while (++i <= c) print fn[i]
  }
{
  # build an array to hold the filenames
  if (NR > 2 && !/\/$/) {
    rec = $0; sub(/([^ \t]+[ \t]+){7}/,"", rec)
    fn[++c] = rec
    }
  }' infile

mh_linkjar

MAVEN(1)							   User Commands							  MAVEN(1)

NAME

       Maven - Creates a link in /usr/share/maven-repo for an existing jar.

SYNOPSIS

       mh_linkjar [option]... [pom] [dest_jar] [link]...

DESCRIPTION

       Create  symlinks for a jar installed by other means. The symlinks created include links to the jar in /usr/share/maven-repo, at the correct
       location for Maven.  It can also create additional links to the jar, usually located in /usr/share/java.

       Where

	      [pom] is the location of the POM associated with the jar to install.

	      GroupId, artifactId and version will be extracted from this file.

	      [dest_jar] is the path of the installed jar, usually located in the

	      usr/share/java folder.

	      [link] is an additional link to the jar to install, usually there should

	      be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging  guidelines.	Note  that
	      there is no need to specify those particular links if the --java-lib option is used.

OPTIONS

       -h --help: show this text

       -V --version: show the version

       -p<package> --package=<package>: name of the Debian package which

	      will contain this jar file

       -e<version>, --set-version=<version>: set the version for the jar,

	      do not use the version declared in the POM file.

       -r<rules> --rules=<rules>: path to the file containing the

	      rules to apply when cleaning the POM.  Optional, the default location is debian/maven.rules Maven rules are used here to extract the
	      groupId, artifactId and version from the POM file.

       -l --java-lib: Optional, if given it will install the jar into

	      /usr/share/java to comply with the Debian Java specification.  The jar will be installed as /usr/share/java/$name-$version.jar and a
	      versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo

       -n<name> --usj-name=<name>: Optional, the name to use when installing the

	      library in /usr/share/java when --java-lib is used.  Defaults to the artifact id found in the POM.

       -j<version> --usj-version=<version>: Optional, the version to use when

	      installing the library in /usr/share/java when --java-lib is used.  Defaults to the version found in the POM.

       -s --no-usj-versionless: Optional, don't install the versionless link

	      in /usr/share/java.  This flag is used only when the -l or --java-lib option is given.

       -c<classifier> --classifier=<classifier>: Optional, the classifier for

	      the jar. Empty by default.

       -v --verbose: show more information while running

       -n --no-act: don't actually do anything, just print the results

       --skip-clean-pom: don't clean the pom, assume that a previous action ran

	      mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar
