Where to put Gradle configuration i e credentials that should not be committed

Question

I m trying to deploy a Gradle-built artifact to a Maven repo  and I need to specify credentials for that  This works fine for now   uploadArchives       repositories           mavenDeployer               repository url   http       nexus content repositories snapshots                      authentication userName   admin   password   admin123                                     But I don t like having to store the credentials in source control  With Maven  I would define a server configuration  and assign credentials in my    m2 settings xml  How do I do something similar with Gradle

You could put the credentials in a properties file and read it using something like this:

Properties props = new Properties() 
props.load(new FileInputStream("yourPath/credentials.properties")) 
project.setProperty('props', props)

Another approach is to define environment variables at the OS level and read them using:

System.getenv()['YOUR_ENV_VARIABLE']

You could also supply variables on the command line with -PmavenUser user -PmavenPassword password   This might be useful you can t use a gradle properties file for some reason  E g  on a build server we re using Gradle with the -g option so that each build plan has it s own GRADLE HOME

For those of you who are building on a MacOS  and don t like leaving your password in clear text on your machine  you can use the keychain tool to store the credentials and then inject it into the build  Credits go to Viktor Eriksson  https   pilloxa gitlab io posts safer-passwords-in-gradle

First answer is still valid  but the API has changed in the past  Since my edit there wasn t accepted I post it as separate answer   The method authentication   is only used to provide the authentication method  e g  Basic  but not any credentials   You also shouldn t use it since it s printing the credentials plain on failure   This his how it should look like in your build gradle      maven           credentials               username   mavenUser              password   mavenPassword                    url  https   maven yourcorp net          In gradle properties in your userhome dir put   mavenUser admin mavenPassword admin123   Also ensure that the GRADLE USER HOME is set to    gradle otherwise the properties file there won t be resolved   See also   https   docs gradle org current userguide build environment html  and  https   docs gradle org current userguide dependency management html  23 6 4 1

If you have user specific credentials   i e each developer might have different username password   then I would recommend using the gradle-properties-plugin    Put defaults in gradle properties Each developer overrides with gradle-local properties   this should be git ignored      This is better than overriding using  USER HOME  gradle gradle properties because different projects might have same property names
