Grails 4 application.groovy：是否允许变量声明？导致从micronaut报告的错误

Question

我们正在从Grails 2迁移到Grails4。极其简化，我们的application.groovy像这样：

def someVar = [:]

environments {

  myGreatApp.brandMap = [
    'dev.analyzor1.com': someVar
  ]
}

这将导致错误，抱怨未创建变量'someVar'。

[我正在迁移一个大型应用程序，将代码从Config.groovy和DataSource.groovy移到application.groovy之后，这样的事情就结束了。

是否存在无法在application.groovy中声明和使用变量的解决方法？谢谢

嗯，事实证明，只删除“ def”就能使错误消失，像这样：
