on Line no. 34 I have 

<packaging>content-package</packaging>

In main pom.xml for Plugin com.day.jcr.vault:content-package-maven-plugin:1.0.2 I have 

<plugin>

                    <groupId>com.day.jcr.vault</groupId>

                    <artifactId>content-package-maven-plugin</artifactId>

                    <version>1.0.2</version>

                    <configuration>

                        <targetURL>http://${aem.host}:${aem.port}/crx/packmgr/service.jsp</targetURL>

                        <userId>${vault.user}</userId>

                        <password>${vault.password}</password>

                    </configuration>

                </plugin>

Hi,

It seems you are not able to connect to adobe repo, could you please try from browser

https://repo.adobe.com/nexus/content/groups/public/com/day/jcr/vault/content-package-maven-plugin/1....

and change your setting.xml to use adobe repo with https

https://repo.adobe.com/nexus/content/groups/public/
