io.github.mkoncek.classpathless.impl.JavaSourceReader

public class JavaSourceReader
extends Object

A simple class to extract information from an InputStream representing a Java source file. Reads by lines removing comments until the first "{" symbol (start of class / interface / enum / ...) declaration. Then removes all the content until the first "@" (annotation). Then searches for the package pattern in the leftover string.
