I followed the following steps it worked:
我按照以下步骤操作：
- Properties->project facets->check java->ok
- convert to maven project.
- 属性->项目方面->检查java->确定
- 转换为 Maven 项目。

assuming you're expecting a call hierarchy in your own code, ensure that all sources are located in src/main/java directory.
假设您希望在自己的代码中使用调用层次结构，请确保所有源都位于 src/main/java 目录中。
Did you installed eclipse m2e plugin ? Do your eclipse recognize the project as a maven project ? (right click > maven > convert to maven project)
您是否安装了 eclipse m2e 插件？您的 Eclipse 是否将该项目识别为 Maven 项目？（右键单击 > maven > 转换为 maven 项目）

I have this quite often. Seems bug in Eclipse. Quit/restart Eclipse seems the easiest to get things working again.
我经常有这种情况。似乎是 Eclipse 中的错误。退出/重新启动 Eclipse 似乎最容易让事情重新开始工作。

Since you are working on a maven project, so Every resource must be included in pom.xml file, if not, the external file must be included as a jar file. Also, if you are not able to open the call hierarchy, the project which is being referred must be open in your Eclipse workspace.
由于是maven项目，所以每个资源都必须包含在pom.xml文件中，如果没有，则必须将外部文件作为jar文件包含。此外，如果您无法打开调用层次结构，则被引用的项目必须在您的 Eclipse 工作区中打开。
