我正在使用 Eclipse STS 3.2.0。这是我到目前为止所做的：
- grails run-app 命令有效
- 圣杯战争指挥部作品
我单独运行 Tomcat，并通过 Tomcat 部署生成的战争。我还粘贴了错误（在 STS 错误报告之后）。
我必须使用 Maven，所以我执行了命令“grails create-pom”，并添加了“pom true”，如下所述：http: //grails.org/doc/2.3.x/ref/Command%20Line/create -pom.html
- 我尝试使用 Maven（添加“pom true”行）和不使用（注释“pom true”行）
我删除了文件夹：“C:\Users\ch.grails\ivy-cache”、“project\target”，再次运行命令“grails clean”和“grails run-war”，错误结果相同。
A) 这是 STS 的完整错误报告：
