sonar.binaries - deprecated property: you should now use sonar.java.binaries
This property is used by java analysis (so I assume that you are analyzing Java code).
The analysis is performed by file by file at the source level, and for proper semantic analysis, the java analyzer reads information about external dependencies from files .class.
Specifically, this is how it works: analyzing A.java, which declares:
class A {
B b;
}
Java- A - B.class, .
? , . ( : : b.foo(): foo()).
