無法在Grails 3中導入grails.plugin.springsecurity.annotation？

我一直在關注Spring Security for Grails 3的Burt Beckwith教程。我在教程中安裝了插件build.gradle，並運行了s2-quickstart，這似乎工作正常。該項目無需投訴即可編譯。無法在Grails 3中導入grails.plugin.springsecurity.annotation？

然而，當我嘗試導入語句

import grails.plugin.springsecurity.annotation.Secured

進口不被識別，也不會建立，與錯誤

Error:(2, 1) Groovyc: unable to resolve class grails.plugin.springsecurity.annotation.Secured

缺少了什麼？

依賴的build.gradle的部分：

dependencies { 
    compile "org.springframework.boot:spring-boot-starter-logging" 
    compile "org.springframework.boot:spring-boot-autoconfigure" 
    compile "org.grails:grails-core" 
    compile "org.springframework.boot:spring-boot-starter-actuator" 
    compile "org.springframework.boot:spring-boot-starter-tomcat" 
    compile "org.grails:grails-dependencies" 
    compile "org.grails:grails-web-boot" 
    compile "org.grails.plugins:cache" 
    compile "org.grails.plugins:scaffolding" 
    compile "org.grails.plugins:hibernate4" 
    compile "org.hibernate:hibernate-ehcache" 
    compile 'org.grails.plugins:spring-security-core:3.1.1' //*** 
    console "org.grails:grails-console" 
    profile "org.grails.profiles:web" 
    runtime "com.bertramlabs.plugins:asset-pipeline-grails:2.8.2" 
    runtime "com.h2database:h2" 
    testCompile "org.grails:grails-plugin-testing" 
    testCompile "org.grails.plugins:geb" 
    testRuntime "org.seleniumhq.selenium:selenium-htmlunit-driver:2.47.1" 
    testRuntime "net.sourceforge.htmlunit:htmlunit:2.18"

嘗試清理並編譯您的項目。 – quindimildev

另外它有助於強制Gradle更新IDE中的依賴項或通過'gradle --refresh-dependencies'。 – Yuri

謝謝你們兩位。 – user1023110
