Gradle Java plugin library not found

I had a problem lately while compiling a java library with Gradle 4.0.1 (this problem also happened with 3.5) on Windows with IntelliJ using the java-library plugin. Here is a snippet of my build script:

buildscript{
    repositories{
        jcenter();
    }
    dependencies{
        classpath 'com.bmuschko:gradle-tomcat-plugin:2.2.5'
        classpath 'org.akhikhl.gretty:gretty:+'
        classpath 'com.github.ben-manes:gradle-versions-plugin:0.15.0'
    }
}

configurations{
    taglibs{ transitive = false}
    enhance
}

repositories {
    mavenCentral()
}

apply plugin: 'java-library'
apply plugin: 'war'
apply plugin: 'com.bmuschko.tomcat'

sourceCompatibility = 1.7

      

        
        
        
      

    

and this is what happens when I try to build:

STRICTLY FAILURE

Total time: 0.115 seconds

Plugin with id 'java-library' not found.

This worked until recently.
