How can I reduced the maven Jar file size Currently 255 MB? - spring-boot

Question

How can I reduce the Maven Executable Jar file size. Currently its 255 MB. It is not allowing to deploy in Cloudformation.
I am doing the deployment via cloudformation --> Lambda and API Getway.
If I can reduce the file from 255 MB, Then my problem will be solved.
I have seen from the JAR file, This below 2 dependency are taking 195 MB.
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.11.931</version>
</dependency>
<dependency>
<groupId>com.amazonaws.serverless</groupId>
<artifactId>aws-serverless-java-container-spring</artifactId>
<version>[0.1,)</version>
What I should to reduce it ?

This is issue is resolved, I am using AWS Dependency -
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.11.931</version>
</dependency>
I don't need all the dependency, I need only S3 and Lambda. So Have remove this dependency. It decrease my Jar file. 255 MB to 50 MB.
