我正在尝试使用Grails 2.4 上的grails-vaadin插件自定义主题，但每次显示我的页面时都会出现以下错误：

我的用户界面已注释：

@Theme("mytheme")
class MyUI extends UI {
   ...
}

我关注this guide

所以我在这条路径中创建了一个styles.scss文件：

web-app/WEB-INF/themes/mytheme/styles.scss

是否有人在Grails 2.4上使用Vaadin scss汇编成功？

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"
}

2 个答案:

答案 0 :(得分：1)

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

使用序列化/反序列化的有问题的DeepCopy部分已在最新的vaadin-sass-compiler版本（7.3.0依赖于此版本）中进行了重构。

或者，您可以强制使用较新的vaadin-sass编译器版本与Vaadin 7.2.6一起使用。

这是插件本身或Vaadin内部的问题。感谢@ artur-signell的评论，现在的实际解决方法是在BuildConfig.groovy中添加更新版本的SASS编译器：

dependencies {
    // ...
    compile 'com.vaadin:vaadin-sass-compiler:0.9.9'
}

编辑 Grails 2.4.3和Vaadin插件7.3.0.1工作直接分叉我
