將Grails應用程序從1.3.7升級到2.0時，拋出了Java NullPointerException異常（完整的錯誤如下）。在從grails 1.3.7升級到2.0之後執行引導時出錯
我使用的是debian squeeze和java版本的OpenJDK「1.6.0_18」，雖然也嘗試過使用預先打包的debian sun-jdk。
我試圖卸載所有的插件沒有運氣;調試模式也不能給我提供線索。我也在開發環境中檢查了我的數據源：
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"
}
}
沒有運氣..任何想法？我查過相關的職位，但不能在這裏找到了同樣的問題...
在此先感謝
