apache/data-generator docker image build fails during Apache Flink workthrough-CodePudding

apache/data-generator docker image build fails during Apache Flink workthrough.
How possibly to overcome or fix this?

Apache Flink workthrough "Real Time Reporting with the Table API" https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/try-flink/table_api/

fails during docker-compose build over apache/data-generator, see log below.
However, I cannot even locate/find where it is on Github or on Docker Hub

https://registry.hub.docker.com/r/apache/data-generator is 404 Not found https://github.com/apache/data-generator is 404 Not found

Line within docker-compose.yml

  data-generator:
      image: apache/data-generator:1

Docker versions used:

docker -v
Docker version 19.03.1, build 74b1e89

CodePudding user response：

How are you building the Docker image? I've just cloned the repository and ran docker build . in the docker/data-generator folder.

https://github.com/apache/flink-playgrounds/tree/master/docker

The image was built successfully for me. Can you run mvn clean install in this folder? I'm wondering if this is more a Maven problem, not being able to access the Internet, then it is a problem with the build itself.

Change from
FROM maven:3.6-jdk-8-slim AS builder
to
FROM maven:3.8-jdk-8-slim AS builder
So the troubled v2.5 of maven-clean-plugin is not used,
as newer maven defaults to newer plugins versions.
