This is a small project to make a very basic filesystem library in Kotlin and was created using the instructions below as part of my application to the JetBrains internship project "TeamCity Kotlin Script build step extension library".

The package is (very creatively) named filesystem.

Usage

Gradle

repositories {
    // other repositories
    maven { url "https://git.koval.net/api/packages/cyclane/maven" }
}

dependencies {
    // other dependencies
    implementation("net.koval.teamcity-build-step-extension-test-task:filesystem:0.1.0")
}

Documentation

Use autocompletion and hover menus in your IDE, or download the generated HTML documentation from the latest release.

Instructions

Create a library implementing four classes:

FSEntry, an abstract class with a name property of the type String;
FSFile extending FSEntry and adding a content property of the type String, which will contain a textual file content;
FSFolder extending FSEntry and adding a content property of the type List<FSEntry> listing files and folders stored within;
FSCreator implementing a single create(entryToCreate: FSEntry, destination: String) method that would create a directory hierarchy described by entryToCreate in a given file system destination path.

Please consider various corner cases and error handling. Unit tests covering various scenarios are expected. The test task could be implemented in either Kotlin or Java.
