Lots of broken source and class path errors in IntelliJ spring boot project?

Question

I recently lost my main Linux development system due to a motherboard failure. Because of this, I had to install on a completely different PC (different manufacturer and motherboard model). Therefore I couldn't use my image backup to restore because I needed a Fresh install of Ubuntu 14.04 because of the difference in PC configuration.

I am now close to having it rebuilt, having done a ton of copying from my non-image backups (rsync, etc.). However, when I go into one of my IntelliJ Java projects that used to work fine, I am getting a lot of broken source and class path errors when I examine the project settings. They are all gradle library paths. I am currently using Gradle 4.3, which I confirmed using the sdkman list command (sdk list gradle). Also, I am using version 172.4343.14 of the IntelliJ Gradle plug-in. I am using IntelliJ IDE version 2017.2.5

How can I fix these errors (shown below)?
