I have the following Dockerfile:

FROM sonarqube

RUN wget
COPY sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/

And I get the following error while copying the file:

Removing intermediate container 63a3ae1d7390
Step 3/3 : COPY sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/
lstat sonar-gitlab-plugin-4.0.0.jar: no such file or directory

How can I copy the file in this case?
