Having used SCM plugins for quite sometime, I thought – WHY I have never used them to clone a repository and while I employ the personal access token (NOW)- The weapon of choice, I have never tried it myself. <\/p>\n\n\n\n

So in this blog, I will attempt to define the basic steps needed to do that.<\/p>\n\n\n\n

Assumptions<\/h2>\n\n\n\n

I am assuming basic knowledge of Maven and plugins, else drop by and ask questions will try to address when I can.<\/p>\n\n\n\n

Learn more about Personal Access Token<\/a><\/p><\/blockquote><\/figure>\n\n\n\n

General Mistake<\/h2>\n\n\n\n

Using git@hostname for checkout.<\/h3>\n\n\n\n
mvn scm:checkout -DcheckoutDirectory=.\/helm-chart2 -DconnectionUrl=scm:git:git@github.com:GRP\/helm-chart.git<\/code><\/pre>\n\n\n\n
If you use this you will get an error like below<\/p>\n\n\n\n
[ERROR] Provider message:\n[ERROR] The git-clone command failed.\n[ERROR] Command output:\n[ERROR] Cloning into 'helm-chart2'...\ngit@github.com: Permission denied (publickey).\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.<\/code><\/pre>\n\n\n\n
Though error is self explanatory but the issue is you are trying to use SSH to checkout and if you read the official documentaion about PAT<\/p>\n\n\n\n
Personal access tokens can only be used for HTTPS Git operations. If your repository uses an SSH remote URL, you will need to switch the remote from SSH to HTTPS<\/a>.<\/p>github.com<\/cite><\/blockquote><\/figure>\n\n\n\n
Many overlook these details and hence try looking everywhere for a quick solution. So, remember to read the documentation before you search elsewhere.<\/p>\n\n\n\n
Change to HTTPS instead of GIT<\/p><\/blockquote><\/figure>\n\n\n\n
mvn scm:checkout -DcheckoutDirectory=.\/helm-chart2 -DconnectionUrl=scm:git:https:\/\/github.com\/GRP\/helm-chart.git<\/code><\/pre>\n\n\n\n
Once you do this you will also need the creds to be used which I have configured in my settings.xml<\/code> for server with id as the hostname github.com<\/code>.<\/p>\n\n\n\n
<servers>\n <server>\n      <id>github.com<\/id>\n      <username>USERNAME<\/username>\n      <password>YOUR PERSONAL ACCESS TOKEN<\/password>\n    <\/server>\n<\/servers><\/code><\/pre>\n\n\n\n
Once you make the changes and issue the command you will eventually see the message below<\/p>\n\n\n\n

The essential two steps prepare<\/code> and perform<\/code> for the release plugin can also be followed subsequently to validate artifact generation as covered in other blog here<\/a>. <\/p>\n\n\n\n
