I am completely new to working with maven. I´m trying to download a jar file from microsofts MMLSPARK library using the command of the screenshot:

I´m getting this error ... No clue what's the problem.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:get (default-cli) on project standalone-pom: Couldn't download artifact: Missing:

CodePudding user response：

Unless you have a weird configuration of maven, the command of the screenshot works! I just executed it. The result is getting a jar, called mmlspark_2.11-1.0.0-rc1.jar in the current working directory.

Also, make sure that you put this exactly:

mvn dependency:get -DremoteRepositories="https://mmlspark.azureedge.net/maven" -Dartifact="com.microsoft.ml.spark:mmlspark_2.11:1.0.0-rc1" -Ddest=.

(Copy&Paste it!)

If you continue getting problems, add the -X flag (debug mode) to the command, it will print more information of what is going on under the hood ...
