Answer 1

我相信您需要将xml-apis的排除添加到您的http-builder依赖项中。

  org.codehaus.groovy.modules.http-builder http-builder 0.5.0 compile    xml-resolver xml-resolver   xml-apis xml-apis    

Answer 2

做一个maven清洁。 当你出去dectates。

首先执行刷新依赖

 grails clean mvn clean grails create-pom grails referseh dependency // this not command line use your STS /GGTS MENU
