earldouglas/sbt-war

This system is an SBT plugin library that provides tools for packaging Java web applications as WAR files and managing embedded server lifecycles. It supports multiple servlet specifications and enables running applications via embedded Tomcat, either from packaged WARs or directly from in-place webapp components. The codebase includes compatibility layers for Scala 2.12 and 3, along with comprehensive scripted tests to verify packaging and server behavior.

4 changes.

The project migrated its build configuration to sbt 1.13.0, replacing the legacy Build.scala script with a modern plugin structure. This period also involved removing outdated SBT container and Jetty runner implementations while establishing a standardized development environment with Nix, Scalafmt, and Scalafix.

5 changes.

This period focused on introducing the SbtWar plugin to standardize WAR packaging and embedded server lifecycle management. The runner was migrated from webapp-runner to Apache Tomcat Embed, enabling both packaged WAR and in-place webapp component serving. Comprehensive test coverage and dependency updates for Scala and Servlet specifications were also implemented.

7 changes.

This period focused on adding Scala 3 and sbt 2.0 compatibility layers to bridge API differences in file handling and classpath resolution. It also significantly expanded test coverage by introducing scripted tests for WAR packaging, servlet API support, and webapp component tasks, alongside a new MUnit-based test template for verifying application logic.

The repository is initialized with configuration files for code style and quality: \.scalafmt.conf\ sets the formatter to version 3.11.5 with Scala 2.12 source 3 dialect, and \.scalafix.conf\ enables the OrganizeImports and RemoveUnused rules. A \shell.nix\ file provides a Nix-based development environment including JDK 17, sbt, Metals, and Neovim, along with shell hooks for running formatting and test commands. Documentation is added via \README.md\ and \CONTRIBUTING.md\, and the project includes a BSD-3-Clause \LICENSE\.

This change introduces the SbtWar plugin, which provides a standardized way to package web applications as WAR files and manage embedded server lifecycles. It adds new sbt settings and tasks including warStart, warStop, warJoin, and warStartPackage to control the server, along with warContextPath to configure the application's context path. The plugin automatically handles the inclusion of webapp resources, compiled classes, and library JARs into the WAR structure and configures the appropriate servlet API dependency (defaulting to Jakarta Servlet 6.1) based on the servletSpec setting.

The \JettyRunner.scala\ template file has been removed from the project. This file previously provided a mechanism to start, reload, and stop a Jetty server instance for specific versions, handling web application context deployment and classloading. Its deletion indicates that this specific embedded server runner implementation is no longer part of the generated or supported codebase.

The legacy SBT container and webapp plugins have been removed from the codebase. This change deletes the core implementation files (\Container.scala\, \Runner.scala\, \WebPlugin.scala\, \WebappPlugin.scala\) and the associated key definitions (\PluginKeys.scala\) that previously provided functionality for running embedded web servers (such as Jetty) and managing web application deployments within the SBT build tool. Users relying on these specific SBT integration features will no longer have access to them through this library.

A new compatibility module has been introduced to support Scala 3 and sbt 2.0. This change adds distinct implementation files for Scala 2.12 and Scala 3 that bridge API differences, specifically handling the conversion between standard Java \File\ objects and sbt's \HashedVirtualFileRef\ for managed jars and classpath resolution. This enables the plugin to function correctly in environments using the newer Scala 3 compiler and sbt 2.0 runtime.

The runner has migrated from webapp-runner to Apache Tomcat Embed, introducing two new execution modes. The WarRunner now starts an embedded Tomcat instance to serve a specified WAR file, configurable via properties (hostname, port, context path, war file). Additionally, a new WebappComponentsRunner allows serving a webapp composed of individual in-place resources and classes without packaging a WAR, mapping specific source files to webapp paths via a resource map configuration. Both runners provide start, join, and stop handles for lifecycle management and include corresponding configuration loaders and tests.

Added scripted test for Servlet 3.0 API compatibility; Added scripted tests for WAR package manifest and exportJars behavior; Added scripted tests for WebappComponentsPlugin war tasks; Added scripted tests for warLib exportJars behavior; Added scripted tests for warStart, warStartPackage, and context-path configuration; Added test fixtures for webapp component rendering; Added test template with MUnit-based verification for servlet and runner components; Added tests for WebappComponents and test utilities.

The project build has been upgraded to sbt version 1.13.0, replacing the previous \Build.scala\ script with a modern \plugins.sbt\ file. This change updates the core build tooling and associated plugins, including scripted-plugin, sbt-pgp (2.3.2), sbt-scalafmt (2.6.2), sbt-scalafix (0.14.9), sbt-buildinfo (0.13.2), and sbt-java-formatter (0.13.1). The removal of the legacy \Build.scala\ eliminates the custom logic for generating Jetty runners and simplifies the build definition to standard sbt plugin declarations.

The build system has been updated to use Scala 2.12.21 and Scala 3.8.4, with the test framework upgraded to MUnit 1.3.6. This change also introduces support for Servlet specifications 3.0, 3.1, 4.0, 5.0, 6.0, and 6.1, utilizing corresponding Tomcat embed versions (8.5.68, 9.0.120, 10.0.27, 10.1.57, and 11.0.25) for the war-runner modules.
