请您参考如下方法:

因为您正在使用2.3.4
不建议安装插件

这是你在做什么

步骤1:打开BuilConfig.groovy

第2步:将此行添加到存储库中

mavenRepo "http://repo.spring.io/milestone/" 
 
repositories { 
        mavenRepo "http://repo.spring.io/milestone/" 
    } 

compile ":spring-security-core:2.0-RC2" 
 
plugins { 
    compile ':spring-security-core:2.0-RC2' 
} 

grails compile
