While creating maven project i am getting this kind of error

[monish_gavali]

The command which i used is :
mvn -B archetype:generate -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=26 -D appTitle="My Project" -D appId="aempanda" -D groupId="com.aempanda.aem" -D artifactId="myproject-aem-panda" -D version="0.0.1-SNAPSHOT" -D aemVersion="6.5.17" -D includeDispatcherConfig=n -D includeExamples=n -DfrontendModule=none

Hello @monish_gavali ,

Maybe you mismatched the archetype version with the AEM version. Check this compatibility chart: https://github.com/adobe/aem-project-archetype/blob/develop/VERSIONS.md 
If any confusion mention your command and other environmental details.
A sample command for you, Change the version according to your AEM setup.

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate \
    -D archetypeGroupId=com.adobe.aem \
    -D archetypeArtifactId=aem-project-archetype \
    -D archetypeVersion=43 \
    -D appTitle="AEM Demo" \
    -D appId="aem-demo \
    -D groupId="com.aem.demo" \
    -D artifactId="aem-demo" \
    -D package="com.aem.demo" \
    -D version="0.0.1-SNAPSHOT" \
    -D aemVersion="6.5.17"

UPDATE:

So the problem is in your archetype version. You are using AEM version 6.5.17 & archetype version 26.
According to the version compatibility, the minimum version will support 28.
But I will suggest using the latest one 43.

I am using this AEM version

Please follow my given command. Hope it will be solved. The only problem was in your archetype version.

Hello @monish_gavali 

You are using a very old archtype. Latest is 43. https://github.com/adobe/aem-project-archetype

The documentation suggests command and the params as well. The documentation suggests aemVersion=6.5.7 for On-premise

Please cross-check, if its an issue on using 6.5.17

Now building this project i am getting the another error

@monish_gavali 

Please try with command

mvn clean install -PautoInstallPackage -Padobe-public

Any connect to insecure sites is disabled in maven by default.

Hi @monish_gavali 

I understand how frustrating it can be to encounter technical difficulties. I went through a similar problem just yesterday.

The latest versions of Java (11.0.19) and mvn (3.9.3) with the specified command below [as @Sady_Rifat  mentioned as well]

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate \
    -D archetypeGroupId=com.adobe.aem \
    -D archetypeArtifactId=aem-project-archetype \
    -D archetypeVersion=43 \
    -D appTitle="WKND Sites Project" \
    -D appId="wknd" \
    -D groupId="com.adobe.aem.guides" \
    -D artifactId="aem-guides-wknd" \
    -D package="com.adobe.aem.guides.wknd" \
    -D version="0.0.1-SNAPSHOT" \
    -D aemVersion="6.5.17"

I trust that this will help you resolve the issue as well.
