android - Android Studio Gradle 构建错误类型代码 82

Question

我对 Kotlin 和 Android Studio 还很陌生。当我尝试向我的 Android 应用程序添加依赖项（依赖项是 json-simple）时，它向我抛出了一个错误，原因为Invalid type code: 82. Gradle 已正确同步，没有任何警告和错误，但是当我尝试运行我的代码时它会抛出这个错误。谁能告诉我如何解决这个问题？堆栈跟踪是： -

我已经尝试了描述这个特定问题的所有其他解决方案。他们都没有工作（包括执行clean任务并再次运行）。我也尝试使用该lintFix任务（尽管我不知道那是什么）来解决问题，但没有奏效。

That issue is describing a dependency conflict - basically the libraries you're using are bringing in two different copies of hamcrest-core, and Gradle doesn't know which one to use.

Googling around it looks like it is json-simple that's pulling in that dependency, and also junit. I don't know a lot about this, but one solution is to add

android {
    ....
    configurations { compile.exclude group: "junit", module: "junit"}
    ....
}

(so add that configurations block in your android section somewhere).

Honestly I'm not totally sure about all this - json-simple has a dependency on JUnit 4.10, and JUnit 4.11 added new Hamcrest matchers - maybe Gradle can't be sure that json-simple will work with the newer library. Excluding JUnit with that compile exclusion might make Gradle ignore it during non-test builds, I'm not sure if it will affect testing though. I'm just giving you stuff to think about if this fix doesn't work and you run into issues!
