# Siapkan proyek Gradle yang menggunakan AWS SDK for Java 2.x
Anda dapat menggunakan [Gradle](https://gradle.org/) untuk menyiapkan dan membangun AWS SDK for Java 2.x proyek.
Langkah awal dalam contoh berikut berasal dari [panduan Memulai Gradle](https://docs.gradle.org/current/samples/sample_building_java_applications.html) untuk versi 8.4. Jika Anda menggunakan versi yang berbeda, hasil Anda mungkin sedikit berbeda.
**Untuk membuat aplikasi Java dengan Gradle (baris perintah)**
1. Buat direktori untuk menampung proyek Anda. Dalam contoh ini, `demo` adalah nama direktori.
1. Di dalam `demo` direktori, jalankan `gradle init` perintah dan berikan nilai yang disorot dengan warna merah seperti yang ditunjukkan pada output baris perintah berikut. Untuk berjalan-jalan, kami memilih Kotlin sebagai bahasa DSL skrip build, tetapi contoh lengkap untuk Groovy juga ditampilkan di akhir topik ini.
```
> gradle init
Starting a Gradle Daemon (subsequent builds will be faster)
Select type of project to generate:
1: basic
2: application
3: library
4: Gradle plugin
Enter selection (default: basic) [1..4] 2
Select implementation language:
1: C++
2: Groovy
3: Java
4: Kotlin
5: Scala
6: Swift
Enter selection (default: Java) [1..6] 3
Generate multiple subprojects for application? (default: no) [yes, no] no
Select build script DSL:
1: Kotlin
2: Groovy
Enter selection (default: Kotlin) [1..2]
Select test framework:
1: JUnit 4
2: TestNG
3: Spock
4: JUnit Jupiter
Enter selection (default: JUnit Jupiter) [1..4] 4
Project name (default: demo):
Source package (default: demo):
Enter target version of Java (min. 7) (default: 11):
Generate build using new APIs and behavior (some features may change in the next minor release)? (default: no) [yes, no]
> Task :init

1. Setelah `init` tugas selesai, `demo` direktori berisi struktur pohon berikut. Kami melihat lebih dekat pada file build utama, `build.gradle.kts` (disorot dengan warna merah), di bagian selanjutnya.
```
├── app
│ ├── build.gradle.kts
│ └── src
│ ├── main
│ │ ├── java
│ │ │ └── demo
│ │ │ └── App.java
│ │ └── resources
│ └── test

│ │ └── AppTest.java
│ └── resources
├── gradle
│ └── wrapper
│ ├── gradle-wrapper.jar
│ └── gradle-wrapper.properties
├── gradlew
├── gradlew.bat
└── settings.gradle.kts
```
`build.gradle.kts`File berisi konten perancah berikut.

1. Gunakan file build Gradle scaffolded sebagai dasar untuk proyek Anda. AWS
1. Untuk mengelola dependensi SDK untuk project Gradle Anda, tambahkan Maven bill of materials (BOM) AWS SDK for Java 2.x untuk bagian file. `dependencies` `build.gradle.kts`
```
...
dependencies {
implementation(platform("software.amazon.awssdk:bom:2.27.21"))
// With the bom declared, you specify individual SDK dependencies without a version.
...
}
...
```
**catatan**
Dalam contoh file build ini, ganti *2.27.21* dengan versi terbaru SDK for Java 2.x. Temukan versi terbaru yang tersedia di repositori [pusat Maven](https://central.sonatype.com/artifact/software.amazon.awssdk/bom/versions).
1. Tentukan modul SDK yang dibutuhkan aplikasi Anda di `dependencies` bagian ini. Sebagai contoh, berikut ini menambahkan ketergantungan pada Amazon Simple Storage Service.
```
...
dependencies {
implementation(platform("software.amazon.awssdk:bom:2.27.21"))
implementation("software.amazon.awssdk:s3")
...
}
...
```
Gradle secara otomatis menyelesaikan versi dependensi yang dideklarasikan dengan menggunakan informasi dari BOM.
Contoh berikut menunjukkan file build Gradle lengkap di Kotlin dan Groovy. DSLs File build berisi dependensi untuk Amazon S3, otentikasi, logging, dan pengujian. Versi sumber dan target Java adalah versi 11.
