英文:
Gradle project builds successfully but IntelliJ cannot resolve references
问题
以下是翻译好的部分：
每次使用以下Kotlin库进行编译并且可以使用，但是IntelliJ的自动补全（以及可能其他一些工具）无法解析这些引用。
https://gitlab.com/7Hazard/altv-kotlin
我通过JitPack将其作为依赖项：https://jitpack.io/#com.gitlab.7Hazard/altv-kotlin
JDK 11，Gradle 6.3（使用wrapper）
Gradle项目可以正常构建，但自动补全功能失效。其他依赖项（如kotlinx.coroutines）正常工作。

altv-kotlin是一个fatjar，甚至在jar中包含了源代码：https://gitlab.com/7Hazard/altv-kotlin/-/blob/master/build.gradle#L53
它本身使用了一个Java依赖项，因此altv-kotlin使用了一些Java代码，最终的fatjar包含了Kotlin和Java的源代码，如果这可能会有影响的话。
是否可能是由于某种原因导致源代码没有正确地放入JAR文件中？我甚至无法让IDEA反编译用于自动补全的引用。我强烈感觉这是与altv-kotlin库特定相关的问题，而不是我的任何环境设置的问题。
我尝试过删除.idea文件夹，使缓存失效/重新启动，为IDEA和Gradle项目更新Kotlin插件，甚至将IDEA从2018更新到2020，但都没有解决问题。我也尝试过以下答案，但问题没有解决：

我还注意到有关Kotlin运行时与库捆绑在一起的警告，但即使不捆绑在一起，IDEA也会报错。
英文:
Every usage of the following Kotlin library compiles and can be used, but IntelliJ's autocomplete (and perhaps others) cannot resolve the references.
https://gitlab.com/7Hazard/altv-kotlin
I am using it as a dependency via JitPack: https://jitpack.io/#com.gitlab.7Hazard/altv-kotlin
JDK 11, Gradle 6.3 (wrapper)
The gradle project builds fine but just autocompletion is broken. Other dependencies like kotlinx.coroutines work fine.
It altv-kotlin is a fatjar and even includes the sources in the jar: https://gitlab.com/7Hazard/altv-kotlin/-/blob/master/build.gradle#L53
It in turn uses a java dependency, so altv-kotlin uses some Java and the end fatjar includes both Kotlin and Java sources if that makes a difference.
Could it be that the source are not being put in the JAR correctly for some reason? I couldn't even get IDEA to decompile the references for autocompletion. I have a strong feeling this is an issue tied to altv-kotlin library specifically, and not any of my environment setup.
I've tried to delete the .idea folder, Invalidate Caches / Restart, update Kotlin plugin for both IDEA and gradle projects and even updated IDEA from 2018 to 2020 with no avail whatsoever.
I tried these answers as well but did not solve the problem:

I also noticed the warning about Kotlin Runtime being bundled with the library, but even without it being bundled in it IDEA complains.

所以，就在本地，我似乎通过重新创建项目并将源代码复制到其中解决了这个问题。似乎起作用了，为什么我不知道。
然而，当从JitPack使用远程依赖时，因为我在JAR中包含了所有的类文件，以使其成为一个fatjar。
jar {
from configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
自从我从jar任务中移除了那行代码以后，IntelliJ IDEA能够正常解析引用了。
英文:
So, locally I seem to have resolved the issue by recreating the project and copying the sources into there. Seems to have worked, why I don't know.
However, when using the remote dependency from JitPack, because I was including all the classfiles in the JAR to have it be a fatjar.
jar {
from configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it)
}
Ever since I removed that line from the jar task, IntelliJ IDEA was able to resolve the references normally.
