Can not ready file text within build.gradle.kts

Question

I am trying to print a kotlin class before compiling it to generate another class. I tried many methods to be sure about printing the file text before compiling it through File.readText() but nothings success-ed always printing code joined with symbols as the following screenshot.

My Gradle code

tasks.findByName("compileKotlin")
    ?.dependsOn(tasks.register("compileKotlin2") {
        doFirst {
            var names2 = "filesPath= "
            fileTree("$buildDir\\classes\\kotlin\\main\\tech\\example\\ecommerce\\ecommerce\\controller\\")
                    .visit {
                        if (this.file.name != "WebPagesController.class") {
                            names2 += this.file.path + "\n"

                            println(file(this.file.path).readText())
                        }
                    }
            println(names2)
        }
    })

            }
        })


tasks.withType<Test> {
    useJUnitPlatform()
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

Any hints are welcomed, Thanks in advance

In fileTree("$buildDir\\classes\\kotlin\\main\\tech\\example\\ecommerce\\ecommerce\\controller\\") using projectDir instead of buildDir with syntax fileTree("$projectDir/src/main/kotlin/tech/example/ecommerce/ecommerce/controller") s
