Problem statement

The command "mvn dependency:resolve" and "mvn dependency:resolve-plugins" fails on internal dependency on a multi-module project. It defeats the attempt to create a dependency layer and increase docker build speed when only application code is changed.

COPY pom.xml .

COPY powerjob-server-remote/pom.xml powerjob-server-remote/pom.xml

sudo echo GRUB_DISABLE_OS_PROBER=false >> /etc/default/grub && sudo update-grub
