AEM 6.1: Back-end Developer Workshop -Video Training Sample Project Maven Error

I am currently taking the AEM 6.1 Back-end Developer Training course and I am stuck on the section "AEM 6.1 Back-end Developer Workshop", video "Installing and Configuring Eclipse". The video told me that if I was still having issues with maven at that point in the video then I needed to come to the forums for assistance. So here i am.

I tried to run "mvn clean install" on the practice project and got a bunch of maven dependency errors. Next the video told us to change the maven settings.xml file to add in a profile for adobe to access the public adobe maven repository. The settings file - which the video told us to add - was not in the student training files that were attached to the video. Therefore I found it online and added this profile to the xml file within <profiles></profiles>:

"<profile>

        <id>adobe-public</id>

        <activation>

            <activeByDefault>false</activeByDefault>

        </activation>

        <properties>

            <releaseRepository-Id>adobe-public-releases</releaseRepository-Id>

            <releaseRepository-Name>Adobe Public Releases</releaseRepository-Name>

            <releaseRepository-URL>http://repo.adobe.com/nexus/content/groups/public</releaseRepository-URL>

        </properties>

        <repositories>

            <repository>

                <id>adobe-public-releases</id>

                <name>Adobe Public Repository</name>

                <url>http://repo.adobe.com/nexus/content/groups/public</url>

                <releases>

                    <enabled>true</enabled>

                    <updatePolicy>never</updatePolicy>

                </releases>

                <snapshots>

                    <enabled>false</enabled>

                </snapshots>

            </repository>

        </repositories>

        <pluginRepositories>

            <pluginRepository>

                <id>adobe-public-releases</id>

                <name>Adobe Public Repository</name>

                <url>http://repo.adobe.com/nexus/content/groups/public</url>

                <releases>

                    <enabled>true</enabled>

                    <updatePolicy>never</updatePolicy>

                </releases>

                <snapshots>

                    <enabled>false</enabled>

                </snapshots>

            </pluginRepository>

        </pluginRepositories>

    </profile>"

Next I ran the command mvn clean install -P full and I still received a dependency error, only this time there were less Errors. Here is the error message in the console:

"C:\VideoTraining\company\sampleproject>mvn clean install -P full

    Ok Ian, I have got it work!  I now get a BUILD SUCCESS.

    Check out the following Maven article Maven – Guide to using Multiple Repositories

    What was needed was some additional tagging in the settings.xml file....

    <settings>

        <profiles>

            <profile>

                <id>adobe-public</id>

                ...

            </profile>

        </profiles>

        <activeProfiles>

            <activeProfile>adobe-public</activeProfile>

        </activeProfiles>

    </settings>

    This did the trick.  By using the <activeProfiles> tag you dont need to use "-P full", you can just run "mvn clean install" and it should work for you hopefully.

    Cheers for the youtube link.  It looks like we are doing the same developer course

    Cheers

    Hi Ian,

    I am having the same issue as you.  I am not been able to obtain the missing settings.xml file either (as you say this isn't in the available student files).

    I haven't got to the second error yet but I will try now.  Can I ask where you found the settings.xml file online?

    Cheers

    Brendan

    Good to see that someone else has the issues...Unfortunately, I don't think any Adobe people are going to get back to us on here anytime soon.

    On another note, if you're looking for videos that are more of a developer tutorial/workshop into components, templates, design, etc... check out these videos (they're by the same guy that did the Adobe training videos - James Talbot). 1 Introduction - YouTube The order of the videos in the series are mixed up, but I've posted the order I'm using in the Introduction video discussion section. Hope it helps!

    Regards,

    Ian

      Here is how i fixed it..

      First i did what brendand72866780 suggesting i.e ( Not sure this is needed even.. but i kept anyway )

      <activeProfiles>

              <activeProfile>adobe-public</activeProfile>

          </activeProfiles>

      My Error was looking like this :

      [ERROR] The build could not read 1 project -> [Help 1]                                                                                                                   

      [ERROR]                                                                                                                                                                  

      [ERROR]   The project com.adobe.training:company-ui:0.0.1-SNAPSHOT (c:\AEM-Video-Training\company\company-ui\pom.xml) has 1 error                           

      [ERROR]     Unresolveable build extension: Plugin com.day.jcr.vault:maven-vault-plugin:0.0.6 or one of its dependencies could not be resolved: Could not find artifact org

      .apache.jackrabbit:jackrabbit-jcr-commons:jar:2.0-alpha8 in adobe-public-releases (http://repo.adobe.com/nexus/content/groups/public) -> [Help 2]                        

                                                                                                                                                                       

      After the above thing,..i did the following and made it work :

      1) Go to the .m2/repository/org\apache\jackrabbit\jackrabbit-jcr-commons\2.0-alpha8

      2) Rename the files to make and remove "lastupdated" from the extension. Finally it should like below:

      • jackrabbit-jcr-commons-2.0-alpha8.jar
      • jackrabbit-jcr-commons-2.0-alpha8.pom

      3) run "mvn clean install -P full" and see Build and deployment successful.

      Looks like it was able to donwload the jackrabbit-jcr-commons version jars however it has wrong extension.. so giving compilation error.

      i fixed it looking the maven error log.. Hope this helps

        The artifact org.apache.jackrabbit:jackrabbit-jcr-commons:jar:2.0-alpha8 is no longer available in adobe's public repository.

        in vaults parent pom file, i.e, .m2/repository/com/day/jcr/vault/parent/2.1.2/parent-2.1.2.pom, change the jackrabbit.version to 2.0.0

        Hope this helps.

          Another alternate solution is to modify in the ui pom.xml

          <artifactId>maven-vault-plugin</artifactId><version>0.0.6</version>

          To  <artifactId>maven-vault-plugin</artifactId><version>0.0.10</version>

          Hi,

          I understand this particular issue.

          I have created a new company project that should work with AEM 6.2.

          You can download it from here[1]. You can use mvn clean install -P full command to install.

          I have also attached my settings.xml[2] file and I think that should help.

          Please try this out and let me know.

          Regards

          Varun Mitra
