Android:使用junit 4.13时无法解析的参考 [英] Android: Unresolved reference when using junit 4.13

问题描述

在gradle依赖项中将junit版本更新为4.13之后，在我的代码中使用时，junit包下的类和批注(例如Assert，@Test等)显示为红色.皮棉检查说:

After updating junit version to 4.13 in gradle dependencies, classes and annotations like Assert, @Test, etc. under the junit package are displayed as red when used in my code. Lint check says:

Unresolved reference: <any junit class>

但是，当我构建并运行测试时，它就可以构建并运行.

However, when I build and run my tests, it will build and run just fine.

我尝试过:

• 重新启动Android Studio
• 使缓存无效并重新启动
• 清理并重建项目
• 添加了testImplementation "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version"

• restarting Android Studio
• Invalidate caches and restart
• Clean and rebuild project
• added testImplementation "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version"

有效的方法是将junit降级为4.12.如何在不降级的情况下摆脱此皮棉错误?

What works is downgrading junit to 4.12. How to get rid of this lint error, without downgrading version?

更新:

• 当我检查ALT + ENTER选项并选择Inspection 'Unresolved reference, in wrong test scope' options> Suppress 'IncorrectScope' for file <name of file>时，它将消除该特定文件的这些皮棉错误.我仍然喜欢不使用Suppress来解决此问题.
• 根据此问题，看来此错误尚未修复.现在我降级到4.12.
• 从依赖项中删除浓缩咖啡和热流道也可以解决此问题.

• When I check ALT + ENTER options and select Inspection 'Unresolved reference, in wrong test scope' options > Suppress 'IncorrectScope' for file <name of file>, it gets rid of these lint errors for that particular file. I still like to solve this problem without using Suppress though.
• According to this issue, it looks like this bug is not fixed yet. For now I'm downgrading to 4.12.
• Removing both espresso and runner from dependencies also fixes the problem.

推荐答案

只需将以下内容添加到您的build.gradle(App)文件中:

Just add the following to your build.gradle (App) file:

configurations.all {
    resolutionStrategy.force "junit:junit:$junit_version"
}

dependencies {
...
}
