But I don't recommend customers Customization I'm also interested in these SAP Artifacts Making a change , Because it violates the opening and closing principle , May cause potential problems .SAP Recommend customers to use Commerce Cloud Self contained Extension Mechanism to customize .

Do not write anything in any directory that is not managed by the build process , Even though these directories are technically writable , Don't do it .

In the build process , The default is Github Warehouse and Docker Registry Are accessible . However, there is no guarantee that the construction process has unrestricted Internet access . Do not use any external services during the build process , Because for the purpose of optimization or safety improvement , Network policy may change at any time . The only resource that the build process can control is the project Git The repository .

Commerce Cloud The build process is not for third parties Artifacts Provide any trusted Repository . By default , It uses publicly available repositories .

The following is a breakdown of repository usage ：

• If in extensioninfo.xml Enable , Core customization Maven Central distributed
• JavaScript Storefront Use yarn Default registry for tool configuration

about yarn and npm - Resolve dependencies in the development process and yarn.lock.json or package-lock.json Submit the file to the code repository . The purpose of this is , For the same input , Even if you repeatedly build , You can get the same output .
