I can build and run my project but my IDE keeps showing errors

问题

I am working on a gradle project. I have no issue building and running my project with gradle and seeing the output. However, in my both NetBeans and Eclipse the following lines are underlined in red:

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import javax.persistence.criteria.CriteriaBuilder;

The error is:

package xxx does not exist

This is actually quite annoying because it means I have no auto-completion and no real ability to detect legitimate build errors before trying to build.

Restarting the IDE does not help. Clean and build does not help. I installed the gradle plugin too, but nothing changed.

How can I change my settings so that NetBeans recognizes this as a gradle project and picks up my dependencies?

My build.gradle, as requested in the comments:

apply plugin: 'java-library'
apply plugin: 'application'

mainClassName = 'server.Server'

repositories {
    jcenter()
}

dependencies {
    implementation 'org.hibernate:hibernate-core:5.2.10.Final'
    implementation 'org.postgresql:postgresql:42.0.0'
    implementation 'com.sparkjava:spark-core:2.5.5'
    implementation 'com.google.code.gson:gson:2.8.0'

    testImplementation 'junit:junit:4.12'
    testImplementation 'org.mockito:mockito-core:2.7.22'
}

Edit

The build script works fine normally, but when I check the project into source control and then check it out on another machine, the problem shows up. I meant to be very clear about that in my original post, but I think I failed.

I faced the same issue some time ago. The only thing helped to me was clearing NetBeans cache. On Windows operating system it is located under C:\Users\<user>\AppData\Local\NetBeans\Cache folder, on Linux operating systems under /home/<user>/.cache/netbeans one. So, what I did was closed NetBeans, deleted folders inside the specified one, and started NetBeans again.

This is really stupid, but I was trying to import the project as an eclipse project. If you just clone the project and open it normally (with the NetBeans gradle plugin installed) it will work.
