Installation

Powertools is available in Maven Central. You can use your favourite dependency management tool to install it

<dependencies>
    ...
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-tracing</artifactId>
        <version>1.12.0</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-logging</artifactId>
        <version>1.12.0</version>
    </dependency>
    <dependency>
        <groupId>software.amazon.lambda</groupId>
        <artifactId>powertools-metrics</artifactId>
        <version>1.12.0</version>
    </dependency>
    ...
</dependencies>

And configure the aspectj-maven-plugin to compile-time weave (CTW) the aws-lambda-powertools-java aspects into your project:

<build>
    <plugins>
        ...
        <plugin>
             <groupId>org.codehaus.mojo</groupId>
             <artifactId>aspectj-maven-plugin</artifactId>
             <version>1.14.0</version>
             <configuration>
                 <source>1.8</source>
                 <target>1.8</target>
                 <complianceLevel>1.8</complianceLevel>
                 <aspectLibraries>
                     <aspectLibrary>
                         <groupId>software.amazon.lambda</groupId>
                         <artifactId>powertools-logging</artifactId>
                     </aspectLibrary>
                     <aspectLibrary>
                         <groupId>software.amazon.lambda</groupId>
                         <artifactId>powertools-tracing</artifactId>
                     </aspectLibrary>
                     <aspectLibrary>
                         <groupId>software.amazon.lambda</groupId>
                         <artifactId>powertools-metrics</artifactId>
                     </aspectLibrary>
                 </aspectLibraries>
             </configuration>
             <executions>
                 <execution>
                     <goals>
                         <goal>compile</goal>
                     </goals>
                 </execution>
             </executions>
        </plugin>
        ...
    </plugins>
</build>
