'Running "ng build" in docker container gives "project definition could not be found"
I'm trying to build an Angular + Spring-boot project using Maven and deploy it as a docker container. To compile the application I run
mvn package
which at some point runs ng build.
It works as intended when I do it on my local machine. But when I copy files into a docker image and try to run mvn package, I get an error

The root directory contains proper angular.json file and Maven downloads correct version of nodejs. Because it is inside a docker image, I am unable to access debug.log. Needless to say I am unexperienced with using a Docker.

Solution 1:[1]
You are in the wrong directory. It can not find the angular.json file.
remove
RUN cd /
from your dockerfile.
Make sure that RUN ls -a returns the directory which holds angular.json, and if it doesn't, configure RUN cd blabla correctly.
Solution 2:[2]
Got the same issue today. Even though RUN ls -la gave me the correct directory, setting an explicit WORKDIR fixed it for me
WORKDIR /var/www
I put this as the second line in my Dockerfile after the FROM ... line. The directory shouldn't matter as WORKDIR creates it if it doesn't exist.
