Package name does not correspond to the file path - IntelliJ

I'm trying to import a project from VCS (well, I'm doing it for the first time actually) and this is my (imported) project's structure:

BTW. this screen is made after many tries of changing these directories' properties (in their context menus).

In these source files' I have a following error:

One time it had nothing against badugi.client but it reported this error only in badugi.server. I have completely no idea how it works...

Also classes in the same directories do not see each other.

This is a code from ClientWorker class which is located (as you can see in the first image) in the same directory as Server so it should know what Server is.

I'm pretty sure this code worked well in my friend's IDE. How do I configure IntelliJ to make it work?

Solution 1:

I had this same issue, and fixed it by modifying my project's .iml file:

From:

<content url="file://$MODULE_DIR$">
  <sourceFolder url="file://$MODULE_DIR$/src/wrong/entry/here" isTestSource="false" />
  <sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />
  <excludeFolder url="file://$MODULE_DIR$/target" />
</content>

To:

<content url="file://$MODULE_DIR$">
  <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />
  <sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />
  <excludeFolder url="file://$MODULE_DIR$/target" />
</content>

Somehow a package folder became specified as the root source directory when this project was imported.

Solution 2:

Judging from the directory structure, you have two packages client and server, but the code expects packages badugi.client and badugi.server.

Here is a way to fix it:

1. Position your cursor to the underlined package statement (package badugi.server)
2. Hit ALT + ENTER
3. Select option Move to package badugi.server. This will automatically fix your directory structure to match the declared package

or

1. Right click src in Project explorer
2. Select New/Package and create package badugi
3. Select client and server packages and drag them to the badugi package

Solution 3:

I've seen this error a few times too, and I've always been able to solve it by correctly identifying the project's module settings. In IntelliJ, right-click on the top level project -> "Open Module Settings". This should open up a window with the entire project structure and content identified as "Source Folders", "Test Source Folders", etc. Make sure these are correctly set. For the "Source Folders", ensure that the folder is your src/ or src/java (or whatever your source language is), as the case may be
