Jenkins脚本控制台/ Scriptler中的Connector/J MySQL驱动程序

Jenkins接缝忽略来自/ etc/environment或/etc/profile.d/jdk.sh的系统CLASSPATH参数.我尝试在Scriptler中运行Groovy脚本,但是我收到此错误:

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
    at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:321

我已经在Jenkins中安装了MySQL数据库插件(https://wiki.jenkins-ci.org/display/JENKINS/MySQL+Database+Plugin),但仍然无法通过在Jenkins控制台和Scriptler中找到的MySQL驱动程序加载:

import groovy.sql.Sql
Sql.newInstance("jdbc:mysql://HOST:3306/DB", "USER", "PASS", "com.mysql.jdbc.Driver")

在我将Jenkis"全局属性">"环境变量"下的CLASSPATH设置为

Name CLASSPATH
Value .:/var/lib/jenkins/plugins/database-mysql/WEB-INF/lib/mysql-connector-java-5.1.21.jar

Jenkins能够运行Jobs,但Jenkins Script Console/Scriptler仍无法找到jar文件.
