我试过下面的代码......
@Grapes([
@Grab('org.hsqldb:hsqldb:2.0.0'),
@GrabConfig(systemClassLoader=true, initContextClassLoader=true)
])
import groovy.sql.Sql
println Class.forName('org.hsqldb.jdbc.JDBCDriver').newInstance()
它适用于groovyConsole,但无法使用Web Start运行.以下是错误消息.
startup failed:
General error during conversion: No suitable ClassLoader found for grab
