Could any one suggest what changes in POM are needed to fix this?

Many Thanks.

Check if Adobe Maven repository configured. You have to do that before this goal will work . Also, you should use version 0.0.20 of the plugin as the current version.

Also make sure that you have changed the directory path to where the pom.xml (your project directory) is situated and then try mvn eclipse:eclipse

[naveed_syed]

Maven repository configuration is in place but still am getting the error.

And this is where from I am building the maven project. In the same path POM is present.

D:\Dex\Key\key>mvn eclipse:eclipse
[INFO] Scanning for projects...

Please find the screen prints attached for the same.

It seems that your content-maven-package plugin is not downloaded or is invalid in your path. Have you followed this (from the link)

Next, copy the Maven configuration file named settings.xml from [install location]\apache-maven-3.0.4\conf\ to your user profile. For example, C:\Users\scottm\.m2\.

You have to configure your settings.xml file to use Adobe’s public repository. For information, see Adobe Public Maven Repository at http://repo.adobe.com/.

Pls make sure you have this jar in C:\Users\<your_username>\.m2\repository\com\day\jcr\vault\content-package-maven-plugin\0.0.20 and it is valid

If it doesn't work, delete this folder and run maven build again, check whether the folder is created again and downloaded with necessary jar files.

@Ahmed Now I get different error message after following your steps:

Change to 1.0.2 version, run the maven archetype command like this

mvn archetype:generate -DarchetypeGroupId=com.day.jcr.vault -DarchetypeArtifactId=multimodule-content-package-archetype -DarchetypeVersion=1.0.2 -DarchetypeRepository=adobe-public-releases

Then go to your key directory and run "mvn eclipse:eclipse"  command

If this doesn't work try this 

mvn archetype:generate -DarchetypeRepository=http://repo.adobe.com/nexus/content/groups/public/ -DarchetypeGroupId=com.day.jcr.vault -DarchetypeArtifactId=multimodule-content-package-archetype    -DarchetypeVersion=1.0.2

Then go to your key directory and run "mvn eclipse:eclipse"  command again

The issue is finally resolved. The problem is not with the version of maven.

Here is the solution:

Go to content folder of your project. Open up the pom.xml from content. In the plugins for group id: com.day.jcr.vault change the filter source to filter.xml

<filterSource>src/main/content/META-INF/vault/filter.xml</filterSource>

This will resolve the issue.

Thanks all.
