Maven cannot download all depedencies with dependency:go-offline

[luizluca]

Hello,

I tried to get all maven dependencies with "mvn dependency:go-offline" in order to build without network. However, when I run "mvn -o compile", it still misses some dependencies:

##[WARNING] The POM for org.apache.maven:maven-plugin-api:jar:3.0 is missing, no dependency information available
##[WARNING] The POM for org.apache.maven:maven-core:jar:3.0 is missing, no dependency information available
##[WARNING] The POM for org.apache.maven:maven-artifact:jar:3.0 is missing, no dependency information available
##[WARNING] The POM for org.apache.maven:maven-settings:jar:3.0 is missing, no dependency information available
##[WARNING] The POM for org.apache.maven:maven-model:jar:3.0 is missing, no dependency information available
##[WARNING] The POM for org.codehaus.plexus:plexus-utils:jar:3.0.24 is missing, no dependency information available
##[WARNING] The POM for org.apache.maven.shared:maven-filtering:jar:3.1.1 is missing, no dependency information available
##[WARNING] The POM for org.codehaus.plexus:plexus-interpolation:jar:1.22 is missing, no dependency information available
##[WARNING] The POM for org.codehaus.plexus:plexus-component-annotations:jar:1.6 is missing, no dependency information available

And when those are provided, I keep getting other warnings about other artifacts.

It seems that pom.xml is not enough for informing maven about its dependencies.

I do not understand maven. That's why I'm opening this issue as you are the best ones to identify if this is a pom.xml or maven's one (or which version it should work).

These are all dependencies that I needed to "dependency:get", that "dependency:go-offline" missed, in order to build offline

Maybe some of them depends on each other but they might give a hint on what is missing

Weird. Those are all things internal to maven, pulled in by core plugins and such.

I've not tried to do "offline" builds of any of our maven stuff in a long time, so I don't really have any experience with why go-offline would not handle those.

One method I've used in the past for grabbing all of the dependencies is to:

1. Wipe the local Maven repository rm -rf ~/.m2/repository
2. Build
3. Look at the artifacts in ~/.m2/repository, those were either required by, or produced by the build

That said, we don't really have any requirements for building offline.
