在Jenkins中运行groovy脚本

Question

我试图在詹金斯上运行groovy脚本。 但我越来越错误。

            import groovy.sql.Sql
            def output = []
            def sql = Sql.newInstance('jdbc:mysql://localhost:3306/logging_schema',     'root', '****', 'com.mysql.jdbc.Driver')
            String sqlString = "SELECT * debug DESC Limit 10;"
            sql.eachRow(sqlString){ row ->  
                output.push(row[0])`enter code here`
            }
            return output

如果需要任何全局配置或任何其他解决方案，请帮助我。

我找到了解决方案，我们必须添加适当的jar文件来运行sql实例。 可以从类路径或工作空间中加载jar文件，在这种情况下，您必须先创建classloader对象，然后尝试如下所述加载jar文件。

import groovy.sql.Sql;

def classLoader = ClassLoader.systemClassLoader
while (classLoader.parent) {
    classLoader = classLoader.parent
}
classLoader.addURL(new File("/var/lib/jenkins/workspace/egsdloen-
logging/mysql/mysql.jar").toURL())
def sql = 
Sql.newInstance('jdbc:mysql://server/dbname', 
'user', 'password', 'com.mysql.jdbc.Driver')
sql.execute 'SELECT * FROM tablename limit 10'
sql.close()
