Great.....
I was just responding with a different soln:
'---------------
Looks like the fatjar does not include junit class. Also, the -jar option
does not use the classpath environment variable.
Here is an excerpt from the man page of java:
-jar
Execute a program encapsulated in a JAR archive. The first argument is the
name of a JAR file instead of a startup class name. In order for this
option to work, the manifest of the JAR file must
............
"When you use this option, the JAR file is the source of all
user classes, and other user class path settings are ignored."
................
So you will have to use the main class in fatjar with the java -classpath
option with all the libraries in the classpath.
Java -cp log4j:junit:fatjar org.apache.zookeeper.util.FatJarMain server
.......
But putting it in build and including it as part of fatjar is much more
convenient!!!
Thanks
