Maven dependecy:go-offline doesn't download transitive dependencies – Docker

I want to add a separate dependency layer to my dockerfile.

I’m running mvn dependencies:go-offline but after that mvn install -o reports that not all deps are found. After inspecting the error message it turned out that no transitive dependencies were downloading. The issue was fixed by explicitly defining all missing packages in pom.xml, but obviously it’s not ideal.

This is my dockerfile

// copy pom.xml

RUN ./mvnw dependency:go-offline

// copy source code

RUN ./mvnw install -o

Is there an alternative to dependency:go-offline, or a flag for that command, that will download all dependencies needed to run install -o, not just direct ones?

UPD:
This are the missing dependencies

    I faced the same issue. For some reason, dependency:go-offline doesn’t add pom files to the local repository.

    Instead, use mvn verify followed by mvn package:

    // copy pom.xml
RUN ./mvnw verify --fail-never

// copy source code
RUN ./mvnw package -DskipTests -o

    According to the comments on issue discussion there were some improvements related to dependency resolution and fetching in newer versions of maven-dependency-plugin (starting with 3.0.0). However by default maven uses version 2.8 of dependency plugin. So in order to use recent versions specify version explicitly:

    // copy pom.xml

RUN ./mvnw org.apache.maven.plugins:maven-dependency-plugin:3.5.0:go-offline

// copy source code

RUN ./mvnw install -o
