PART - A Nexus Maven Creation

1. Create User Account in Nexus

4. Make Sure , enable the HTTP user authentication for Maven Central Repository part of newly created Group Repository.

5. Verify the Repository  Access using the URL

PART - B  Maven Config files creation

1. Create Maven Master Password Creation

$ mvn --encrypt-master-password <PASSWORD>

2. Save the result into a file "settings-security.xml" 

<settingsSecurity>
<master>{XOZTXCnPjDsHo1jxbPOEdjSCkMamoy4fgdfYej7588I=}</master>
</settingsSecurity>
Notes:

If you like to keep the password somewhere USB to plug & Build 

Store the file into USB drive specific folder 

like '/Volumes/mySecureUsb/secure/settings-security.xml' & use it.

<settingsSecurity>

    <relocation>/Volumes/mySecureUsb/secure/settings-security.xml</relocation></settingsSecurity>

3. Using Master password encrypt Repository Password to be used in pom.xml for build

For Example :

Repository URL : https://www.tamilcloud.com:8443/repository/maven-central/

Repository User Name : tamilarasan

Repository Password  : abcdefgh => needs to be encrypted to be used in CI CD pipeline

$ mvn --encrypt-password "abcdefgh" -s Settings.xml -Dsettings.security=settings-security.xml

4. Update the encrypted password into Settings.xml in server password Section

<servers>
<server>
<id>nexus</id>
<username>tamilarasan</username>
<password>{zVwvg21CdkIHM9hA5GsKv+9rzIZlslT3qAmkxcvh+xA=}</password> <!-- Encrypted Repo Password -->
</server>
</servers>
