Question

我正在尝试将Grails应用程序从1.0.3升级到1.3.7。

我已经创建了一个Grails 1.3.7项目，并且尽力将新项目和其他文件复制到新项目中。当然，出了点问题：

$ grails run-app

如果查看此堆栈跟踪，您将找不到我的应用程序代码的引用，这使我很难跟踪。

我需要一些建议，我可以检查这可能是这个错误。这是我的applicationContext.xml，这似乎不太可能是问题所在：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

非常感谢帮助，如果需要更多信息，请告诉我。

Answer 1

从我将项目从Grails 1.0.3升级到1.3.7时所做的注释（并非所有这些步骤都可能是必需的）：

确保您的项目源位于包中（即“com.companyname.projectname”，而不是默认包中）
确保插件源也在包中（即“org.grails.pluginname”，而不是默认包中）
从project \ lib目录中删除hibernate.jar（hibernate现在是一个插件）
将GRAILS_HOME设置为新版本，创建一个虚拟项目并将新的BuildConfig.groovy复制到要升级的项目中
运行“grails升级”并在提示中回答“y”

Answer 2

看看stacktrace.log，它可能会让你更好地了解实际问题。还要在“grails run-app”之前尝试“grails clean”和“grails compile”，看看它是否是旧垃圾的问题。

将Grails升级到1.3.7，需要故障排除帮助
