Did you install Ant 1.6.5 yourself? This sounds like there may be
multiple Ant installations - for example, one might be packaged with
RedHat by default.

Trying something like "which ant" might give you some help.

FYI, in Ant 1.6 the Launcher class it's complaining about is in
ANT_HOME/lib/ant-launcher.jar. This is a change from Ant 1.5.

Subject: Problems installing Ant under Linux Red Hat: can't find
org.apache.ant.launch.Launcher class


 Hi all,
  
  I'm trying to instal Ant 1.6.5 under Red Hat, I have set all the env
variable required but I can't still  run ant.
  
  Actually I can run
  ant -version
  
  but when I try with
  
  ant -diagnostics or just ant
  
  I have to the following message from the shell
  
   ant -diagnostics
  Exception in thread "main" java.lang.NoClassDefFoundError:
org.apache.tools.ant.launch.Launcher
     at gnu.gcj.runtime.FirstThread.run() (/usr/lib64/libgcj.so.5.0.0)
     at _Jv_ThreadRun(java.lang.Thread) (/usr/lib64/libgcj.so.5.0.0)
     at _Jv_RunMain(java.lang.Class, byte const, int, byte const,
boolean) (/usr/lib64/libgcj.so.5.0.0)

     at __libc_start_main (/lib64/tls/libc-2.3.4.so)
     at _Jv_RegisterClasses (/net/hc291/gianni/java.version=1.4.2)
  
  
  I tried putting the jars in the lib directory into the CLASSPATH but
it doesn't work as well.
  
  Anybody has any suggestions?
  
  Thanks !
  
  Daniele
