Ant on Mac OS X
I have been trying to get Ant working on my Mac. The problem I am
running into is whenever I type 'ant' from the command line, I get
the following error:
java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/AntMain
at java.lang.ClassLoader.defineClass1(Native Method)

at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67)
I have cleared out my CLASSPATH. Ant is currently installed at: /
Developer/Java/Ant. I have set ANT_HOME to /Developer/Java/Ant. I
have added $ANT_HOME/bin to my PATH, too. What gives?
I am running 10.4.10. I have tried running 'ant -version' but I still
get the same error. Can someone clue me in on what I am doing wrong?
Thanks,
Jason

Re: Ant on Mac OS X (Solved)
Posted by Jason Barker <ja...@phonedir.com>.
I have figured it out. I have a jar file (selenium-server.jar) in my
Extensions folder (/Library/Java/Extensions) which also contained the
class files for Ant. As soon as I removed the jar file from that
folder, I was able to run Ant without any problems. What's more is
that it seems like Ant can be run from the command line without
having to set ANT_HOME and JAVA_HOME.
Thanks!

From the command line, when I type:
% ls $ANT_HOME/lib
I get the following output:
README ant-apache-resolver.jar ant-
jmf.jar ant-stylebook.jar ant-xslp.jar
ant-antlr.jar ant-commons-logging.jar ant-
jsch.jar ant-swing.jar ant.jar
ant-apache-bcel.jar ant-commons-net.jar ant-

launcher.jar ant-vaj.jar xercesImpl.jar
ant-apache-log4j.jar ant-jai.jar ant-
netrexx.jar ant-weblogic.jar xml-apis.jar
ant-apache-oro.jar ant-javamail.jar ant-
nodeps.jar ant-xalan1.jar
ant-apache-regexp.jar ant-jdepend.jar ant-
starteam.jar ant-xalan2.jar
Also, I have tried setting JAVA_HOME to /System/Library/Frameworks/
JavaVM.framework/Home and also leaving it empty. It does not seem to
have an effect.
Any other ideas?

You must not have the Ant jar in $ANT_HOME/lib. Or something. You are
receiving the
classic error meaning the Ant classes were not found by Java itself.
