# Powertools for AWS Lambda (Java)
   [](https://app.codecov.io/gh/aws-powertools/powertools-lambda-java)
Powertools for AWS Lambda (Java) is a developer toolkit to implement Serverless best practices and increase developer velocity.
> Also available in [Python](https://github.com/aws-powertools/powertools-lambda-python), [TypeScript](https://github.com/aws-powertools/powertools-lambda-typescript), and [.NET](https://github.com/aws-powertools/powertools-lambda-dotnet).

## Installation
Powertools for AWS Lambda (Java) is available in Maven Central. You can use your favourite dependency management tool to install it
### Maven:
```xml
...
software.amazon.lambda
powertools-tracing
1.19.0-SNAPSHOT
software.amazon.lambda
powertools-logging
1.19.0-SNAPSHOT
software.amazon.lambda
powertools-metrics
1.19.0-SNAPSHOT
...
```
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.
Maven - Java 11 and newer
```xml
...
dev.aspectj
aspectj-maven-plugin
1.13.1
1.8
1.8
1.8
software.amazon.lambda
powertools-logging
software.amazon.lambda
powertools-tracing
software.amazon.lambda
powertools-metrics
compile
...
```
Maven - Java 8
```xml
...
org.codehaus.mojo
aspectj-maven-plugin
1.14.0
1.8
1.8
1.8
software.amazon.lambda
powertools-logging
software.amazon.lambda
powertools-tracing
software.amazon.lambda
powertools-metrics
compile
...
```
Gradle - Java 11+
```groovy
plugins {
id 'java'
id 'io.freefair.aspectj.post-compile-weaving' version '8.2.2'
}
// the freefair aspect plugins targets gradle 8.2.1
// https://docs.freefair.io/gradle-plugins/8.2.2/reference/
wrapper {
gradleVersion = "8.2.1"
}
repositories {
mavenCentral()
}
dependencies {
aspect 'software.amazon.lambda:powertools-logging:{{ powertools.version }}'
aspect 'software.amazon.lambda:powertools-tracing:{{ powertools.version }}'
aspect 'software.amazon.lambda:powertools-metrics:{{ powertools.version }}'
implementation "org.aspectj:aspectjrt:1.9.8.RC3"
}
sourceCompatibility = 11
targetCompatibility = 11
```
Gradle - Java 8
```groovy
plugins {
id 'java'
id 'io.freefair.aspectj.post-compile-weaving' version '6.6.3'
}
// the freefair aspect plugins targets gradle 7.6.1
// https://docs.freefair.io/gradle-plugins/6.6.3/reference/
wrapper {
gradleVersion = "7.6.1"
}
repositories {
mavenCentral()
}
dependencies {
aspect 'software.amazon.lambda:powertools-logging:{{ powertools.version }}'
aspect 'software.amazon.lambda:powertools-tracing:{{ powertools.version }}'
aspect 'software.amazon.lambda:powertools-metrics:{{ powertools.version }}'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
```
### Java Compatibility
Powertools for AWS Lambda (Java) supports all Java version from 8 up to 21 as well as the
[corresponding Lambda runtimes](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html).
For the modules that provide annotations, Powertools for AWS Lambda (Java) leverages the **aspectj** library.
You may need to add the good version of `aspectjrt` to your dependencies based on the JDK used for building your function:
```xml
org.aspectj
aspectjrt
1.9.??
```
JDK - aspectj dependency matrix
| JDK version | aspectj version |
|-------------|-----------------|
| `1.8` | `1.9.7` |
| `11-17` | `1.9.20.1` |
| `21` | `1.9.21` |
