Development discontinued

In newer gradle versions this plugin no longer works and we are not planning to fix it. The biggest problem - eager initialization of properties - is solved in gradle itself. While it still provides a popup that's useful when you don't want to store your password in any form we don't feel like it's really worth the effort and the hacks it needed!

Old docs follow:

Lazy credentials gradle plugin

This is plugin adds lazyCredentials extension that can be used to replace credentials in maven repo definition. Those credentials won't be evaluated until it's necessary. It can also prompt user for credentials.

When to use this plugin

It's useful when project uses gradle's maven-publish plugin - you can use properties to pass repo username and password and tasks not requiring them won't fail - you only need to provide them when necessary. This also simplifies config for team members who don't have to (or are not allowed to) publish to maven repo - they can completely ignore configuring credentials.

Furthermore, since plugin can prompt you for password (or username and password) you don't have to store password in properties file or put it as parameter.

How to use this plugin

You can find instruction on how to add this plugin on gradle plugin portal.

Basic usage is quite simple:

publishing {
  publications {
    maven(MavenPublication) {
      artifactId 'your-artifact'
      from components.java
    }
  }
  repositories {
    maven {
      url 'http://your.repo.com/repo/'
      lazyCredentials {
        passwordProperty "mvnPassword"
        usernameProperty "mvnUsername"
      }
    }
  }
}

You can also use password and username instead of passwordProperty and usernameProperty. You can provide String, GString or Closure as password and username. GString and Closure will be evaluated only when necessary. It will evaluate them only once though.

publishing {
  publications {
    maven(MavenPublication) {
      artifactId 'your-artifact'
      from components.java
    }
  }
  repositories {
    maven {
      url 'http://your.repo.com/repo/'
      lazyCredentials {
        password "${->lazy}"
        username {
          getUsername()
        }
      }
    }
  }
}
