This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
- The compiler is configured to retain compatibility with Kotlin 1.3.
- Explicit API mode is not yet enabled but could be in the future.
- Some exceptions thrown by Kotlin have changed to NullPointerException,
see https://youtrack.jetbrains.com/issue/KT-22275 for more details.
Closes gh-24171
Prior to this commit, the Spring Framework build would partially use the
dependency management plugin to import and enforce BOMs.
This commit applies the dependency management plugin to all Java
projects and regroups all version management declaration in the root
`build.gradle` file (versions and exclusions).
Some versions are overridden in specific modules for
backwards-compatibility reasons or extended support.
This commit also adds the Gradle versions plugin that checks for
dependency upgrades in artifact repositories and produces a report; you
can use the following:
./gradlew dependencyUpdates
This commit reorganizes tasks and scripts in the build to only apply
them where they're needed. We're considering here 3 "types" of projects
in our build:
* the root project, handling documentation, publishing, etc
* framework modules (a project that's published as a spring artifact)
* internal modules, such as the BOM, our coroutines support and our
integration-tests
With this change, we're strealining the project configuration for all
spring modules and only applying plugins when needed (typically our
kotlin support).

Prior to this commit, the Spring Framework build would be using the
propdeps Gradle plugin to introduce two new configurations to the build:
"optional" and "provided". This would also configure related conventions
for IDEs, adding those configurations to published POMs.
This commit removes the need for this plugin and creates instead a
custom plugin for an "optional" configuration. While the Eclipse IDE
support is still supported, there is no need for specific conventions
for IntelliJ IDEA anymore.
This new plugin does not introduce the "provided" scope, as
"compileOnly" and "testCompileOnly" are here for that.
Also as of this commit, optional/provided dependencies are not published
with the Spring Framework modules POMs annymore.
Generally, these dependencies do not provide actionable information to
the developers reading / tools consuming the published POMs.
Optional/Provided dependencies are **not**:
* dependencies you can add to enable some supported feature
* dependencies versions that you can use to figure out CVEs or bugs
* dependencies that might be missing in existing Spring applications
In the context of Spring Framework, optional dependencies are just
libraries are Spring is compiling against for various technical reasons.
With that in mind, we are not publishing that information anymore.
See gh-23282
As of 1.3.40, Kotlin now provides a kotlin-scripting-jsr223-embeddable
dependency which:
- Fixes classloading related issues
- Provides out of the box JSR 223 support
- Is compatible with Spring Boot Fat Jar mechanism
This commit updates Spring Framework tests and documentation accordingly.
Closes gh-23165
