Target "provision.tests" does not exist in the project "Eclipse SDK build"

[Eric Jansen]

I tried to install eclipse from /usr/ports/java/eclipse, then some
restricted options demanding me to download directly from websites
listed on. I downloaded then and copy them into /usr/ports/distfiles/:
jce_policy-6.zip
jdk-6u3-fcs-bin-b05-jrl-24_sep_2007.jar
jdk-6u3-fcs-mozilla_headers-b05-unix-24_sep_2007.jar
jdk-6u3-fcs-src-b05-jrl-24_sep_2007.jar
jdk16.patches
diablo-caffe-freebsd7-i386-1.6.0_07-b02.tar.bz2
diablo-jre1.6.0_07
diablo-latte-freebsd7-i386-1.6.0_07-b02.tar.bz2

Error results:

What's exactly that I missed during the installation?
Thank you in advance.
