groovy script classpath

Question

I\'m writing a script in Groovy and I would like someone to be able to execute it simply by running ./myscript.groovy. However, this script requires a 3rd party

Answer 1

You should be able to do:

import groovy.sql.Sql

@GrabConfig(systemClassLoader=true)
@Grab('mysql:mysql-connector-java:5.1.19')
def getConnection() {
    def dbUrl = 'jdbc:mysql://database1.c5vveqm7rqgx.eu-west-1.rds.amazonaws.com:3306/vouchers_prod'
    def dbUser = 'pucaroot'
    def dbPassword = 'bigsecret'
    def driverClass = "com.mysql.jdbc.Driver"

    return Sql.newInstance(dbUrl, dbUser, dbPassword, driverClass)
}

getConnection().class

Two more options:

1. Put the jar in ${user.home}/.groovy/lib

2. If the jar is in a known location, use this code to load it into the current class loader:

   this.class.classLoader.rootLoader.addURL( new URL() )
