Intellij doesn't show run button
提问by Ugnius Malūkas
Intellij doesn't show run button even if that file is in srcfolder.
即使该文件在src文件夹中，Intellij 也不显示运行按钮。
Maybe do you know what to do?
也许你知道该怎么做？
P. s. It's strange because that file used to show run button but after recloning git repository it just doesn't show any more.
P.S. 这很奇怪，因为该文件曾经显示运行按钮，但在重新克隆 git 存储库后，它不再显示。

In my case Run/Debugbuttons disappeared for all projects after updating from IDEA 2019.2 to 2019.3. Tried checking Sources Root, Invalidate Caches, Run/Debug configurations etc - no luck. Only restoring Run/Debug action group helped:
在我的情况下，从 IDEA 2019.2 更新到 2019.3 后，所有项目的运行/调试按钮都消失了。尝试检查 Sources Root、Invalidate Caches、Run/Debug 配置等 - 没有运气。只有恢复运行/调试操作组有帮助：
Right click on main toolbar (where the button disappeared) > Customize Menus and Toolbars... > select Run/Debug > Restore Run/Debug.
右键单击主工具栏（按钮消失的地方）> 自定义菜单和工具栏... > 选择运行/调试 > 恢复运行/调试。
