Installation

Powertools for AWS Lambda (Java) is available in Maven Central. You can use your favourite dependency management tool to install it

Maven:

<dependencies>
    ...
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-tracing</artifactId>
        <version>1.16.1</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-logging</artifactId>
        <version>1.16.1</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-metrics</artifactId>
        <version>1.16.1</version>
    </dependency>
    ...
</dependencies>

Next, configure the aspectj-maven-plugin to compile-time weave (CTW) the aws-lambda-powertools-java aspects into your project. A different configuration is needed for projects on Java 8.
