Очистить кэш сборки:

rm -r $HOME/.gradle/caches/

Использовать системные переменные в build.gradle.kts:

  repositories {
    maven {
      name = "RepoName"
      url = URI("https://oss.sonatype.org/service/local/staging/deploy/maven2/")
      credentials {
        username = System.getenv("MAVEN_USERNAME")
        password = System.getenv("MAVEN_PASSWORD")
      }
    }
  }

Использовать параметры из gradle.properties:

~/.gradle/gradle.properties:

mavenUsername=user
mavenPassword=pass

build.gradle.kts:

repositories {
    maven {
        url = URI("https://registry.company.org/repository/maven-group")
        credentials {
            username = property("mavenUsername") as String
            password = property("mavenPassword") as String
        }
    }
}
