[SOLVED] How to fix: maven-dependency-plugin:3.1.1:unpack Unable to find/resolve artifact.
After a day of trial and error, I realized something. The maven plugins are trying to build the parent module (rst_bav). This module is just a container declaring dependencies and maven plugins. I never intended it to be built.
Therefore the solution is to move all plugin declarations to the child modules (rst_eureka, rst_admin, rst_mail, rst_config) and remove them from the parent module (rst_bav).
There is also an answer here on stackoverflow. Matts had the same problem as me and wrote a plugin to orchestrate plugin execution for maven child modules, while the plugins themselves are declared in the parent module. I did not try said plugin though.
Original Question
I am trying to package a multi module maven project. During the package phase, all dependecies shall be unpacked into the /target/dependencies/ directory, so that I can build a docker image as described here: https://spring.io/guides/gs/spring-boot-docker/
My multi module maven project looks like this:
rst_bav (packaging="pom")
|_ rst_eureka (packaging="jar")
|_ rst_admin (packaging="jar")
|_ rst_mail (packaging="jar")
|_ rst_config (packaging="jar")
The build fails on trying to unpack rst_bav, saying it does not exist in the local nexus.
"C:\Program Files\Java\jdk-11.0.1\bin\java.exe" -Dmaven.multiModuleProjectDirectory=C:\git\rst_bav "-Dmaven.home=C:\Program Files\apache-maven-3.6.0" "-Dclassworlds.conf=C:\Program Files\apache-maven-3.6.0\bin\m2.conf" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.2\lib\idea_rt.jar=60959:C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.2\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\apache-maven-3.6.0\boot\plexus-classworlds-2.5.2.jar" org.codehaus.classworlds.Launcher -Didea.version=2018.3.2 clean install package -e -U

dependency:unpack always downloads artifacts to default local repository first, and then
unpacks the artifacts to the desired locations. For large size unique snapshot artifacts,
the downloads can quickly fill up default local repository, and therefore local disk, after
many executions. To clean up the downloaded artifacts as part the build, set
localRepositoryDirectory's value to a location in your project's target directory.
