Detects incorrect dependency notations.

• Instances of Dependency;
• String or CharSequence values, for example 'org.gradle:gradle-core:1.0';
• Maps, for example [group: 'org.gradle', name: 'gradle-core', version: '1.0'];
• FileCollections, for example files('some.jar', 'someOther.jar');
• Projects, for example project(':some:project:path');
• ClassPathNotation, for example gradleApi();
• Lists of dependency notations, for example ['org.gradle:gradle-core:1.0'];
• (Gradle 7.0+) Version catalog accessors, for example libs.groovy.core.

Example:

dependencies {
  implementation(1) // reports '1'
}
