Question

使用grails GWT plugin时，我很难刷新我的依赖项。

我插入了

compile ":gwt:0.8"

进入我的BuildConfig.groovy并运行：grails refresh-dependencies。我的Grails版本是2.3M1。

进程因以下错误而停止。我该如何解决这个问题？

Answer 1

我成功安装了gwt插件。步骤进行：

已安装Grails 2.3.0.M1，已创建GRAILS_HOME。
已安装的GWT SDK
创建了指向gwt文件夹的env var GWT_HOME。
创建了一个新项目
更改了BuildConfig.groovy，添加了依赖项compile ":gwt:0.8"
运行命令grails compile --refresh-dependencies

Grails 2.3.M1中的默认依赖项解析引擎更改为Aether（因此排除在外）。由于这是一个里程碑版本，最初可能会有一些hickup。如果您希望作为依赖项解析程序返回maven或ivy，请使用

grails.project.dependency.resolver = "maven" // or ivy
