Grails 2.3.0升级问题与windows斜杠

Question

在升级现有应用程序(最近升级,并使用Grails 2.2.4)时,我升级了应用程序的两个组件中使用的公共模块(称为myApp-common).这顺利进行,但是当我尝试升级第一个依赖模块时,我在运行"grails upgrade"命令时收到了这个堆栈跟踪.

1 error (Use --stacktrace to see the full trace)

After some googling, it looked like this was related to a known issue with having \u in the code when not followed by a hex code. After removing all instances thereof, it still gave the same error. Next I changed the workspace where the code was at the time from C:\unique_workspace\Iteration21 to C:\x_unique_workspace\Iteration21 to remove the \u in the workspace address. Doing this and attempting the upgrade again resulted in this stacktrace:

It appears that the upgrade script is choking on the '\' character while it updates the common plugin that the module requires, but I am having trouble discerning a way around it.

我在尝试执行升级（spring-security-core 插件）时遇到了同样的问题。我将以下属性添加到 BuildConfig.groovy 中来修复它：

grails.project.work.dir = "target/work"
grails.project.plugins.dir = "${grails.project.work.dir}/plugins"
