# TeamCity Kotlin Script build step extension library - Test Task

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".

## Usage

### Gradle
```kotlin
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](https://git.koval.net/cyclane/teamcity-build-step-extension-test-task/releases/download/v0.1.1/filesystem-0.1.0-javadoc.zip)
from the [latest release](https://git.koval.net/cyclane/teamcity-build-step-extension-test-task/releases).

## 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.
