这是我的版本gradle至少是相关的部分

plugins {
    id 'maven-publish'
    id 'java'
    id "it.tellnet.sass" version "1.2"
}

apply plugin: "it.tellnet.sass"
configurations {
    runtime
    configurations.runtime.extendsFrom configurations.sassRuntime
}

sass {
    sassDir = 'server/src/main/webapp/stylesheets/scss'
    cssDir = 'server/src/main/webapp/stylesheets/css'
    minify = false
    silenceErrors = false
}
错误确实消失了，因为我将导入从bootstrap_覆盖移动到同一行，但输出文件基本上是oit品牌文件，没有任何替换，大约150行。我使用ruby编译了这些文件，css大约有5000行长

这是所要求的stacktrace

BUILD FAILED
我不知道如何解决这个问题。

可能是gradle插件中的一个bug。以防万一，使用--stacktrace重新运行构建。您将获得NullPointerException stracktrace。它可能会帮助你找到你为什么得到它。@dwursteisen我已经把它缩小到引导导入。当我将该行注释掉时，SCS将编译。我还将stacktrace添加到了原始问题中。我在同一个地方得到了相同的异常（
adjust
call），对于将来的参考来说似乎很奇怪：在我的案例中，问题在于定义为
rgba（255，41，41）
的颜色变量不正确，并且在用
rgb（255，41，41）替换它之后
