When you are using ProGuard for obfuscation of some of your NetBeans module code on a Mac running OS X and you will most likely refer to rt.jar in your build.xml and get and error about missing rt.jar.
One quick fix solving this could be the following which helped me.
On your Mac open a terminal and change directory to
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib
now just softlink to classes.jar via
me$ sudo ln -s ../../Classes/classes.jar rt.jar
Brilliant! Thanks both...google and you!
ReplyDeleteGREAT!!!!!!!
ReplyDeleteHi,
ReplyDeleteI have this with the Lion 10.7.3 jdk 1.6.0
$pwd
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib
$ls -l rt.jar
lrwxr-xr-x 1 root wheel 25B Mar 14 23:18 rt.jar -> ../../Classes/classes.jar
$pwd
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/jre/lib
$ls -l
total 8
lrwxr-xr-x 1 root wheel 16B Mar 14 23:20 rt.jar -> ../../lib/rt.jar
Thanks again for this nice post....
Thanx. Do I read this that you simply created 2 softlinks on 10.7.3 with jdk 1.6.0 to support both jdk and jre consumption ?
DeleteHi,
ReplyDeleteThanks for this workaround! I'm using:
Darwin ArjonesBook.local 11.4.0 Darwin Kernel Version 11.4.0: Mon Apr 9 19:32:15 PDT 2012; root:xnu-1699.26.8~1/RELEASE_X86_64 x86_64
And besides the SYMLINK you described, on my env I had to create a ref. to jre. see commands below.
Hope it can be useful!
cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
sudo ln -s /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar rt.jar
# ALSO NECESSSARY
cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
sudo ln -s . jre
Live saver!
