Launching Cloud Data Flow task failes with IllegalStateException Failed to resolve MavenResource-CodePudding

I am trying to register an application in Spring Cloud Data Flow server through UI. I am using an internal S3 maven repo where my artifact is published and available currently.

I have custom maven repo configured with my data flow server as below based on this documentation (Section B.1). Also created an user in AWS with read access to pull the artifact.

{
    "maven": {
        "local-repository": "local",
        "remote-repositories": {
            "repo1": {
                "url": "s3://custom-maven-repo.s3.us-east-1.amazonaws.com/release",
                "auth": {
                    "username": "<aws-access-key-id>",
                    "password": "<aws-secret-key>"
                }
            }
        }
    }
}

Though app registration is successful, I am unable to successfully launch a task based on this app. I am receiving the below error.

{
    "errors": [{
            "message": "Failed to resolve MavenResource: com.hidglobal.migration:migration-job:jar:0.0.1. Configured remote repositories: : [repo1],[springRepo]",
            "logref": "IllegalStateException",
            "_links": {
                "self": {
                    "href": "/"
                }
            }
        }
    ]
}

Is this issue is because my SCDF server is unable to connect to the remote repository? I so how do I configure s3 maven repo

CodePudding user response：

I solved this problem by making my S3 bucket as a static site (Storage) and used CloudFront to access the artifact via HTTPS URL. Registered the app through the http url instead of maven uri
