Upgraded to a new version of IntelliJ 2024.1.6 and my java project will not build

I have just upgraded to IntelliJ IDEA 2024.1.6 (Ultimate Edition) Now my java project is not compiling and getting strange results.

I have tried to invalidate the caches.

I have right clicked on the pom.xml and selected maven->reload project

The image below is the best way to describe my Issue.

When i build the project it fails with org.jsoup does not exist, although to me it appears that it does as seen in the image.

I am a loss of what to do or how to fix this.

Anything else I can provide here to help me resolve this issue please let me know

This is my pom.xml

Solution

In some rare cases IDEA's caches may get corrupted during the upgrade, causing a mismatch between Maven's pom.xml and IDEA's internal Project Model. I would not necessarily recommend removing .idea folder, as it stores Project-specific settings (Run Configurations, etc.).

Try the following, instead:

Close all instances of IDEA
Rename or remove the System Directory
Re-import the Project: Open -> Navigate to the Project's directory -> Double-click the root pom.xml -> Open as Project
