I am not sure what the classloader business is about. I get your -e
examplke running on Linux:
$ groovy -e "import groovy.xml.MarkupBuilder;
import groovy.sql.Sql
groovy.grape.Grape.grab(group:'com.h2database', module:'h2', version:'1.4.188')
def sql = Sql.newInstance('jdbc:h2:mem:test_mem', 'sa', '', 'org.h2.Driver');
println(sql)
"
