[英]Getting an error “unable to resolve class org.jfree.util.Log grails” after upgrading grails from 1.3.x to 2.0.4
我已经在grails 1.3.x版本中开发了应用程序，我已升级到2.0.4，我有一个Log.debug()语句并导入import org.jfree.util.Log Log.debug()包，当我运行该应用程序时，它给了我错误。
unable to resolve class org.jfree.util.Log grails
升级后log4j的配置是什么，如何解决此问题。
这是登录grails 2.0的方法
package org.other
import org.apache.commons.logging.LogFactory
class MyClass { private static final log = LogFactory.getLog(this) … }
然后使用log.debug（...）
请参阅日志指南
