Possibility to configure RTC BuilfForge for ANT project

Hi Team,
We have a project which is not a Maven project but it is an ANT project(build.xml).
Please help me for following concerns :
1). Can we create automatic Build artifacts i.e BuildDefinition for this ANT project?
     If yes please guide me.
2). If No ,we need to convert ANT project into Maven project ?
3). In one of my Build definition XML, I have following :
<step id="4"
                    description="Copy Ears"
                    dir="${BASE_DIR}"
                    timeout="1000"
                    failnotify="29"
                    threadable="N"
                    onfail="H"
                    command="find . -name *8.5-SNAPSHOT*.jar -exec cp -p \{\} &quot;${BASE_DIR}${SWITCH}${PRIMARY_DIR}${SWITCH}Release${SWITCH}&quot; \\;"/>
This will find all the jars by searching name by "8.5-SNAPSHOT".
Can we use any regular expression while searching : for example :
command="find . -name *8.5-SNAPSHOT*.jar  --->can be written as ==>
command="find . -name [a-zA-Z_0-9]8.5-SNAPSHOT[a-z].jar
