类必须声明为抽象或实现convertToLegacyCheckingEqualizer [英] class must either be declared abstract or implement convertToLegacyCheckingEqualizer

问题描述

我在IntelliJ 2017.1 Ultimate中编写了一个简单的测试用例.而且我在IntelliJ中看到一个绝对虚假的错误消息

I wrote a simple Test case in IntelliJ 2017.1 Ultimate. And I see an absolutely bogus error message in IntelliJ

class must either be declared abstract or implement convertToLegacyCheckingEqualizer

我的代码可以编译并运行得很好，但是IntelliJ版始终为每个测试类显示此消息.

My code compiles and runs absolutely fine but IntelliJ edition always shows this message for each and every test class.

我在Google上搜索后发现完全不令人满意的答案，例如

I googled and found totally unsatisfactory answers like

* I restarted my IDE to solve the problem
* I deleted my idea project and recreated it to solve the problem
* I cleared ivy cache to solve the problem.

此解决方案只是错误的，不能真正解决问题.

This solutions are just wrong and don't really address the problem.

推荐答案

尝试一下:在 IntelliJ 中，转到 File 菜单，然后选择使缓存无效/重新启动... 选项.在出现的对话框中，点击无效并重新启动按钮.

Give this a try: in IntelliJ, go to the File menu, then select the Invalidate Caches / Restart... option. On the resulting dialog, click the Invalidate and Restart button.

IntelliJ 重新启动后，检查是否仍然存在相同的问题.

After IntelliJ has restarted, check whether you still have the same problem.
