Method Details

load

@Nullable
public static com.google.auth.oauth2.GoogleCredentials load(@Nullable
 String serviceAccountKeyFile)
                                                     throws IOException

Loads a service-account key file, or returns null to leave application-default credentials in effect.

The path and parser failure are deliberately absent from the exception. A path can expose a mounted secret's name, and parser exceptions can echo credential material. The actionable distinction is whether the configured file could be loaded at all.

Parameters:

serviceAccountKeyFile - the configured key-file path, or null for ADC

Returns:

the scoped service-account credentials, or null for ADC

Throws:

IOException - if the configured file cannot be read as a service-account key
