Apache Maven vs fastlane

Apache Maven is a free build tool for Java projects. It uses a project object model, or POM, and plugins to manage compilation, testing and documentation through a uniform build system. Maven manages dependencies, including transitive dependencies and automatic updates, and can download them from a central repository. Project metadata can produce outputs such as JARs, WARs and distributions. Maven can also generate project information, including changelogs, cross-referenced sources, dependency lists and unit test reports. Java or scripting-language plugins extend it, and it can work with source control systems such as Subversion or Git to manage tag-based releases. It runs on Windows, macOS and Linux. Maven 3.10 and later requires JDK 8 or above to execute, while toolchains can target other JDK versions. Its project layout is opinionated, so projects with unusual structures that cannot be reorganized may have to give up some Maven features or Maven itself. The software is distributed under Apache License 2.0; its listed plan costs nothing.

fastlane is a free, open-source platform for automating iOS and Android app development and release workflows. Teams define workflows as lanes and can run them with a single command. A lane can manage build numbering, code signing, builds, beta uploads and changelog creation; fastlane also supports store releases, including metadata and screenshot management and submission for review. It can create localized app store screenshots for the languages and devices an app supports. The site lists support for more than 15 beta testing services, including TestFlight, Crashlytics Beta, Play and Hockey. Documentation describes integrations with more than 400 tools and services, including major CI systems, alongside community-built actions and plugins. For iOS signing, signing identities and profiles can be kept in a private encrypted Git repository and synced between machines. fastlane runs on a user's machine or server, and its documentation says credentials and other sensitive information stay there. macOS is officially supported; Linux and Windows are partially supported. The project uses the MIT license.
