To configure encrypted passwords, create a master password by running mvn -encrypt-master-password followed by your choice of master password.įor example, you can execute the command into command prompt as: mvn -encrypt-master-password for now – this is done via CLI after master password has been created and stored in appropriate location.server entries in the ~/.m2/settings.xml have passwords and/or keystore passphrases encrypted.this password is created first via CLI for now.this file either contains encrypted master password, used to encrypt other passwords or it can contain a relocation – reference to another file, possibly on removable storage.authorized users have an additional ~/.m2/settings-security.xml file.The implemented solution adds the following capabilities: this applies to any server operations, requiring authorization, not only deployment.some users have the privilege to deploy Maven artifacts to repositories, some users don’t have.multiple users share the same build machine (server, CI box).The main use case, addressed by this solution is: Luckily maven 2.1 version onward provides a facility to encrypt passwords in ~/.m2/settings.xml file. Therefore the ~/.m2/settings.xml file quickly becomes a security risk as it contains plain-text passwords to source control and repository managers. Once you start to use maven to deploy software to remote repositories and to interact with source control systems directly, you will start to put a number of passwords into maven ~/.m2/settings.xml file and without a mechanism for encrypting these passwords. ![]() ![]() So people may be disturbed by leaving unencrypted passwords in the ~/.m2/settings.xml file in a production system. These jar files or libraries are downloaded when they are included in the project’s pom.xml and when you run build on the project using maven tool. Let’s say, when you as a user want to access the protected repository then you need to use your credentials (username/password) to access the repository for downloading required jar files. The maven’s configuration or setting file, settings.xml, which contains all the required configurations such as repository, server etc will be updated here. The user here is the person who is going to access the remote maven’s protected repository. Here I will show you how to encrypt user passwords in maven’s ~/.m2/settings.xml file.
