Jar too big for upload with CDK as

[msche]

I'm trying to deploy a very simple function using Spring Cloud (latest version) with CDK but get the following exception:

Resource handler returned message: "Unzipped size must be smaller than 262144000 bytes (Service: Lambda, Status Code: 400, Request ID: 699d5bbd-756e-4271-ba07-8da8a7c26ef6) (SDK Attempt Count: 1)" (RequestToken: 91dba09a-8eef-ce8c-163a-a31c7da9d05a, HandlerErrorCode: InvalidRequest)

I'm using the spring-boot-thin-layout and shade plugin. The resulting jar is 172Mb compressed.

The POM is as follows:

Can anybody guide me in the good direction on how to solve this.

It was because I combines the CDK infra definition and business logic in one module and had to include aws-cdk-lib. This blowed up the size of the jar. After setting the scope to provided the deployment was successful.
