Java Maven throws "package does not exist"

Question

I have an APIClient class autogenerated from an OpenAPI yml file. Compiling was successful but running the app throws exceptions "java: package com.google.gson.reflect does not exist" and "java: package okhttp3 does not exist". The pom file contains these two packages. The digitalform ords client used the same codes but worked fine. I compared these two pom files and there are no differences. why does it throw runtime errors?

Error message:

Answer 1

after clone/rebuild the application, I got everything working now. Intellij is just weird.

Answer 2

In such cases you can use maven command line application. Its name is mvn. All you have to do is change CWD(current working directory) to your project directory

$ cd /../../your_project_dir

And you can run mvn here. It's simple. IntelliJ and Eclipse use cache mechanism everywhere. Because of caching problems such problems can occur.
