This example provides details about these missing areas. 6 | 7 | You only need to call [`AwsDynamoDbLocalTestUtils#initSqLite()`](src/test/java/io/redskap/java/aws/dynamodb/example/local/testing/AwsDynamoDbLocalTestUtils.java#L30) in test classes before you plan to use the local database. You can find detailed description below about setting up local testing. 8 | 9 | **You can copy the content to reuse it in your own project.** 10 | 11 | ## Setting Up DynamoDB Local with Gradle 12 | 13 | AWS DynamoDB documentation has a detailed description about [Setting Up DynamoDB Local](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.html), but it does not mention Gradle setup. 14 | 15 | You can find a working setup in ``build.gradle`` file (with EU repositories). 16 | 17 | For each regions, first you need to set the proper repository: 18 | * ```groovy 19 | repositories { 20 | mavenCentral() 21 | 22 | maven { 23 | name "DynamoDB Local Release Repository - Asia Pacific (Mumbai) Region" 24 | url "https://s3.ap-south-1.amazonaws.com/dynamodb-local-mumbai/release" 25 | } 26 | } 27 | ``` 28 | * ```groovy 29 | repositories { 30 | mavenCentral() 31 | 32 | maven { 33 | name "DynamoDB Local Release Repository - Asia Pacific (Singapore) Region" 34 | url "https://s3-ap-southeast-1.amazonaws.com/dynamodb-local-singapore/release" 35 | } 36 | } 37 | ``` 38 | * ```groovy 39 | repositories { 40 | mavenCentral() 41 | 42 | maven { 43 | name "DynamoDB Local Release Repository - Asia Pacific (Tokyo) Region" 44 | url "https://s3-ap-northeast-1.amazonaws.com/dynamodb-local-tokyo/release" 45 | } 46 | } 47 | ``` 48 | * ```groovy 49 | repositories { 50 | mavenCentral() 51 | 52 | maven { 53 | name "DynamoDB Local Release Repository - EU (Frankfurt) Region" 54 | url "https://s3.eu-central-1.amazonaws.com/dynamodb-local-frankfurt/release" 55 | } 56 | } 57 | ``` 58 | * ```groovy 59 | repositories { 60 | mavenCentral() 61 | 62 | maven { 63 | name "DynamoDB Local Release Repository - South America (São Paulo) Region" 64 | url "https://s3-sa-east-1.amazonaws.com/dynamodb-local-sao-paulo" 65 | } 66 | } 67 | ``` 68 | * ```groovy 69 | repositories { 70 | mavenCentral() 71 | 72 | maven { 73 | name "DynamoDB Local Release Repository - US West (Oregon) Region" 74 | url "https://s3-us-west-2.amazonaws.com/dynamodb-local/release" 75 | } 76 | } 77 | ``` 78 | 79 | Then set the dependency: 80 | ```groovy 81 | dependencies { 82 | testCompile group: 'com.amazonaws', name: 'DynamoDBLocal', version: '1.11.119' 83 | } 84 | ``` 85 | 86 | You can get the version numbers from each regions: 87 | * dynamodb-local-mumbai - https://s3.ap-south-1.amazonaws.com/dynamodb-local-mumbai/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 88 | * dynamodb-local-singapore - https://s3-ap-southeast-1.amazonaws.com/dynamodb-local-singapore/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 89 | * dynamodb-local-tokyo - https://s3-ap-northeast-1.amazonaws.com/dynamodb-local-tokyo/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 90 | * dynamodb-local-frankfurt - https://s3.eu-central-1.amazonaws.com/dynamodb-local-frankfurt/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 91 | * dynamodb-local-sao-paulo - https://s3-sa-east-1.amazonaws.com/dynamodb-local-sao-paulo/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 92 | * dynamodb-local-oregon - https://s3-us-west-2.amazonaws.com/dynamodb-local/release/com/amazonaws/DynamoDBLocal/maven-metadata.xml 93 | 94 | ## Initialize sqlite4java for testing 95 | 96 | AWS DynamoDB provides possibility to test locally and it requires `sqlite4java.library.path` system property to be set. In the [official example](https://github.com/aws-samples/aws-dynamodb-examples) it is set for the Maven project. 97 | 98 | If you run it from Gradle or from your IDE, local database might not start as the sqlite4java native libraries are not available. These are downloaded as a dependency of `DynamoDBLocal` artifact, but it is not visible by default.

If the property is already initialized, the call will skip initialization. 140 | 141 | There is an example test, that uses the local database.
