从Grails1.3.7升级到2.0后执行引导时出错

将grails应用程序从1.3.7升级到2.0后，将抛出一个java NullPointerException（下面是完整的错误）

我使用的是debian squeeze和java版本OpenJDK“1.6.0_18”，不过我也尝试过使用预先打包的debian sun jdk

我尝试卸载所有插件，但没有成功；调试模式也没有给我任何线索。我还检查了开发环境中的数据源：

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    dialect = org.hibernate.dialect.MySQLInnoDBDialect
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = true
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    development {
        dataSource {

        dbCreate = "create-drop" // one of 'create', 'create-drop','update'
    //url = "jdbc:hsqldb:mem:devDB"  //hsql
        url = "jdbc:mysql://server.domain/database" //mysql
        username = "user"
        password = "password"

    }
}

一点运气都没有。。有什么想法吗？我查看了相关帖子，但在这里找不到相同的问题

提前谢谢

检查BuildConfig.groovy 确保已启用相应的JDBC库，如以下行中所述：

依赖关系{ 运行时“mysql:mysql连接器java:5.1.16” }

---

或者，如果您希望添加库而不依赖于Grails加载库机制，只需将jar放到项目的/lib文件夹中即可

仅为了解决此问题，它与acegi插件中的spring安全插件ugprade有关。我使用了spring安全插件的默认类和属性，一切正常。

我收到了类似的错误，在.groovy域类中使用了Java关键字

protected

。我刚刚删除了

protected

关键字，效果很好。我想如果我将文件重命名为

.java

，它也会工作得很好
