java - 构建 JAR 后无法构建 Android，并出现错误 "Failed resolution of R$color"

Question

当我使用实现 project(path: ':rocket_library') 运行项目时，资源(例如:R.color.color_rocket_web)文件工作正常。但是在构建 JAR 文件并包含 JAR 后，找不到项目资源。是否可以将资源文件附加到 JAR 中？

从项目中找不到颜色:

库代码:在运行时也没有从 Libray 中找到。

import infix.imrankst1221.rocket.library.R

fun getThemePrimaryColor(mContext : Context): Int {
    return PreferenceUtils.getInstance().getIntegerValue(Constants.KEY_COLOR_PRIMARY, ContextCompat.getColor(mContext, R.color.my_color))
}

运行时异常:

这一定是评论!!我没有发表评论的特权

你尝试过这些吗..？

1. 清理项目并重建。(构建 -> 清理项目并重建)
2. 使缓存无效并重新启动(文件 -> 使缓存无效/重新启动)
