我在Java 8中使用了Grails 2.5.6(由sdkman设置)，当我将一些插件添加到依赖项时，例如“org.grails.plugins:quartz:2.0.12”或“org.grails.plugins:grails-java8”: 1.2.2'启动Grails应用程序时出现错误。

我得到的Stacktrace:

请您参考如下方法:

您正试图在Grails 2.x中使用Grails 3+插件，但它们不兼容。使用https://grails.org/plugins/中的插件信息，并确保将依赖项信息添加到BuildConfig.groovy的plugins块中，而不是dependencies块中，因为这是针对jar依赖项的(Grails 2插件打包为.zip文件)

看起来Grails 2的Quartz插件的最新版本是v1.0.2，因此您可以将其添加为

plugins { 
    ... 
    compile ':quartz:1.0.2' 
}
