When I install ant and ant-optional (version 1.6.2-r2), the commons-net jar is not installed properly. To fix it, I simply add a link in /usr/share/ant/lib to /usr/share/commons-net/lib/commons-net.jar. root:/usr/share/ant/lib# ln /usr/share/commons-net/lib/commons-net.jar Reproducible: Always Steps to Reproduce: 1.emerge ant-optional 2.Create a build.xml file with an ftp task Actual Results: BUILD FAILED java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient Expected Results: build successfully Portage 2.0.50-r9 (default-x86-2004.0, gcc-3.3.3, glibc-2.3.3.20040420-r1, 2.6.7-gentoo-r10) ================================================================= System uname: 2.6.7-gentoo-r10 i686 Intel(R) Pentium(R) M processor 1.60GHz Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium4 -O3 -pipe -funroll-loops" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -mcpu=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="ftp:///ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ http://mirror.datapipe.net/gentoo http://mirror.datapipe.net/gentoo http://gentoo.mirrors.pair.com/ http://open-systems.ufl.edu/mirrors/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acpi alsa apache2 arts avi berkdb bidi cdr crypt cups dvd emacs encode esd foomaticdb gdbm gif gpm gtk gtk2 imlib java jpeg libg++ libwww mad mikmod motif mpeg ncurses nls oggvorbis opengl oss pam pcmcia pdflib perl png python quicktime readline samba sdl slang spell ssl svga tcpd truetype usb x86 xml2 xmms xv zlib"
Actually, it appears that this is a classpath issue. The commons-net jar should be in the classpath when Ant runs. By creating a link in the lib directory, I had Ant automatically add the jar to the classpath (however, I don't believe that this is the correct way to fix the issue). Also, I get the feeling that there may be other jars that should be in the classpath too (try out all the options for the ftp task).
fixed in 1.6.2-r3
