我试图在Grails 2.4 上的grails-vaadin插件中使用自定义主题，但是每次显示页面时，我都会遇到以下错误:

我的用户界面带有注释: 
@Theme("mytheme")
class MyUI extends UI {
   ...
}

我关注了 this guide

所以我在以下路径中创建了一个styles.scss文件: 
web-app/WEB-INF/themes/mytheme/styles.scss

有人在Grails 2.4上成功使用了Vaadin scss编译吗？

注意:我的插件配置是: 
plugins {
    // plugins for the build system only
    build ":tomcat:7.0.55"

    // plugins for the compile step
    compile ":scaffolding:2.1.2"
    compile ':cache:1.1.7'
    compile ":asset-pipeline:1.9.6"
    compile ":vaadin:7.2.5"

    // plugins needed at runtime but not for compilation
    runtime ":hibernate4:4.3.5.5" // or ":hibernate:3.6.10.17"
    runtime ":database-migration:1.4.0"
    runtime ":jquery:1.11.1"
}

最佳答案

您应该尝试升级到Vaadin 7.3.0.beta1，然后查看它是否可以解决问题。

最新的vaadin-sass-compiler版本(依赖于7.3.0)已经重构了使用序列化/反序列化的有问题的DeepCopy部分。

或者，您可以强制将新的vaadin-sass-compiler版本与Vaadin 7.2.6一起使用。
