Subject Execution error help - java.lang.NoClassDefFoundError
Date Sun, 07 Mar 2010 03:36:13 GMT
Hi,

I tried building the 6.0.x tomcat source. From the installation looks like
we had to execute "ant download" and then "ant".

Executing "ant download" completed fine and said build successful. But
executing "ant" after it fails with this error:

Any idea if some envt variable is messed up ?

sudo ant
Buildfile: build.xml

build-prepare:
   [delete] Deleting directory /usr/share/tomcat-trunk/
output/build/temp
    [mkdir] Created dir: /usr/share/tomcat-trunk/output/build/temp

compile:
    [javac] Compiling 1058 source files to
/usr/share/tomcat-trunk/output/classes

BUILD FAILED
