Re: [rules-users] Re: beginner needs help
Hello Alexander,
Thanks a lot!
I tried to install a fresh copy of Drools, and what I have done is:
1. checked out everything from
http://anonsvn.labs.jboss.com/labs/jbossrules/trunk using Subversion.
2. cd $DROOLS_HOME
3. mvn clean
4.mvn -Declipse -Ddocumentation clean install
-DlocalEclipseDrop=/folder/jboss-rules/local-eclipse-drop-mirror
But I got a lot of error from step 4. as

probably you have not all needed JAR files on your classpath.
It depends on your needs, which JAR files you have to include, but I think,
for the beginning, when you want to build rules using DRL, you have to
reference:
- drools-core***.jar
- drools-compiler***.jar
both from the drools main directory and further
- antlr-runtime***.jar
- core-3.2.3***.jar
- mvel***.jar
from the lib directory.
I guess you know how to include the JARs in the classpath?
If there will be similar exceptions afterwards, perhaps have a look at the
remaining JARs in these both directorys, if you need one of them.

The documentation of Drools should help you to continue. See
http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/html/ch03.html#d0e1349
for the section on needed JAR files. At bottom there is an interesting
document referenced: readme_dependencies.txt
