我创建了一个带有5个Domain类的Grails 3.1.0项目3个域是Spring Security Plugin中的User，Role和UserRole，另外2个是1对多关系。
我正在连接到MySQL 5.6，我的dbCreate设置为更新。
当使用干净的数据库启动项目时，会创建表并且一切都很顺利但是当我使用已创建表的数据库启动项目时，启动失败并出现NullPointerException。
每次运行应用程序时，我都需要删除并创建数据库。
堆栈跟踪：
@AfterMethod(alwaysRun=true)
public void catchExceptions(ITestResult result){
Calendar calendar = Calendar.getInstance();
SimpleDateFormat formater = new SimpleDateFormat("dd_MM_yyyy_hh_mm_ss");
String methodName = result.getName();
if(!result.isSuccess()){
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
try {
FileUtils.copyFile(scrFile, new File((String) PathConverter.convert("failure_screenshots/"+methodName+"_"+formater.format(calendar.getTime())+".png")));
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
