go: jsii doesn't handle module imports for private modules

[yuriy-yarosh]

Describe the bug

In case of a private monorepo, that uses manually rewritten module paths.

module github.com/org/privaterepo/platform/packages/my-cdk8s-turbochart

go 1.20

require (
	github.com/org/privaterepo/platform/utility/crds v0.0.0
)

replace github.com/org/privaterepo/platform/utility/crds => ../../utility/crds

JSII is unable to pick import the shared replaced module.

Expected Behavior

It should be able to pick modules using their respective absolute paths.

Current Behavior

It panics with a failed import

panic: Passed to parameter props of new xrd_apiextensionscrossplaneio.CompositeResourceDefinition: Unable to deserialize value as xrd_apiextensionscrossplaneio.CompositeResourceDefinitionProps | undefined

                                            ╰─ Module 'k8s' not found

Reproduction Steps

Create two golang modules

1. github.com/org/repo/module1, github.com/org/repo/module2
2. make a direct replacement in module1 referencing module2 using relative path

module github.com/org/repo/module1

go 1.20

require (
	github.com/org/repo/module2 v0.0.0
)

replace 	github.com/org/repo/module2 => ../module2

3. JSII will fail to import.

Possible Solution

Implement the respective module rewriting handler for go.mod.

Additional Information/Context

I'm using cdk8s specifically for codegen but not sure if it's a cdk8s issue and the respective handler should be implemented there, as well.

Can provide a sample cdk8s project, for reference and reproducibility.

I've created a separate CDK8S issue with more details regarding my cdk8s use case.

It's an issue where jsii does not generate anything for struct passed into interface{}, also not sure if it's relevant to CDK8S or jsii, but I'd like to get some form of exception, instead of completely blank synthesis.

SDK version used

github.com/aws/jsii-runtime-go v1.81.0 github.com/aws/constructs-go/constructs/v10 v10.2.22

Environment details (OS name and version, etc.)

ArchLinux node.js lts-hydrogen go 1.20

[yuriy-yarosh]

I don't think it's all about monorepo's - I've switched to a single private go module and JSII still unable to find the k8s imported package.
