Question

我尝试添加drools插件： https://grails.org/plugin/drools 到Grails中的webapp，只需在BuildConfig.groovy中添加它：

plugins {
    // plugins for the build system only
    build ":tomcat:7.0.55"

    // plugins for the compile step
    compile ":scaffolding:2.1.2"
    compile ':cache:1.1.8'
    compile "org.grails.plugins:mail:1.0.7"
    compile ":rest-client-builder:2.0.3"
    compile ":spring-security-core:2.0-RC3"
    compile ":spring-security-oauth2-provider:1.0.5.2"
    compile ":browser-detection:0.4.3"
    compile ":asset-pipeline:2.1.5"
    compile ":remote-pagination:0.4.8"
    compile ":drools:1.1.0"

    // plugins needed at runtime but not for compilation
    runtime ":hibernate4:4.3.6.1" // or ":hibernate:3.6.10.18"
    runtime ":database-migration:1.4.0"
    runtime ":jquery:1.11.1"
    runtime ':twitter-bootstrap:3.3.1'
}

，但我收到了一个错误：

似乎Drools和spring-security-oauth2-provider之间存在冲突。

好的，我通过添加：

解决了这个问题

compile ":cxf:2.1.1"

到BuildConfig插件。
