# 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".

The package is (very creatively) named `filesystem`.

## 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/v0.1.0/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.
