Maven2 problem to access plugins repository ! - apache

i just come to install maven2, after configuring the settings.xml in ${user.home}/.m2 and fixing a proxy error. Now by executing the command :
mvn -U archetype:create -DgroupId=maven-test -DartifactId=maven-test
-DpackageName=net.ensode.maventest
i get this error :
[INFO] Scanning for projects...

any idea of what could cause it ?
thanks !

I think that the most likely cause is that your proxy requires you to authenticate, and you haven't configured the authentication details into your settings.xml file.

Maven - doesnt download from https://repo1.maven.org/maven2 but trying to download from http://repo1.maven.org/maven2

I m trying to run mvn site. I tried even running dependency tree. But still i m getting the following error on console. Ideally it should fetch from https and not from http. How do we get the maven from downloading from https and not from http ?

Would be great if some one can suggest on what is wrong with my system?
I had this same issue and just like the comments suggested it was the maven proxy. Setup in \conf\settings.xml

How to get 'mvn lagom:runAll' to get my service listening on a port?

I was having problems getting my first service to run and decided to add the hello-api and hello-impl projects from the lagom Maven archtype project to see if it would work. It did but mine do not.
Background
Since other team members are pure Java developers, I was trying to avoid leveraging sbt and activator. Thus, the objective is that everything works in maven.
Here's a snippet of the 'mvn install' script output to show the other services built.
$ mvn install

What step(s) did I miss?
Each of your <service>-impl projects need to:
Invoke the lagom-maven-plugin
Configure it with the property <lagomService>true</lagomService>
Here's an example snippet of what you need to add to your pom.xml file in each service implementation project:
<build>
<plugins>
<plugin>
<groupId>com.lightbend.lagom</groupId>
<artifactId>lagom-maven-plugin</artifactId>
<configuration>
<lagomService>true</lagomService>
</configuration>
</plugin>
</plugins>
</build>
The Lagom documentation has more details in the page titled Defining a Lagom build

It's comand is correct and on my computer run correctly. But you have Error transferring file. So on this branch you may read about this error.
