                </configuration>
            </plugin>

could you tell me how to fix this error?

Answer 1

Your assumption seems about right. If you have a line in your Dockerfile like this, it will probably cause an error:

RUN mkdir /codemanager & WORKDIR /codemanager

Change to this, because the Dockerfile commands RUN and WORKDIR must be on separate lines:

RUN mkdir /codemanager
WORKDIR /codemanager
