我正在尝试使用带有gradle的scss来生成css文件。但是，在运行gradle build
时出现错误我收到的错误是
Execution failed for task ':sassCompile'.
> java.lang.NullPointerException (no error message)
我有以下scss代码

这是我的build.gradle，至少是相关部分
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
}
错误确实消失了我将导入从bootstrap_overrides移到同一行，但输出文件基本上是oit-brand文件，没有任何替换，大约150行。我用ruby编译了这些文件，css大约是5000行。
这是请求的堆栈跟踪
