Migrate `CoroutinesUtils` from Kotlin code to Java and drop the
`kotlin-coroutines` module.
This update removes the need for Kotlin tooling IDE plugins to be
installed.
Closes gh-27379
Prior to this commit, we registered custom values in the build scan for
the main and test toolchains based on input values provided via the
mainToolchain and testToolchain project properties.
Beginning with this commit, the custom values we register are based on
the available metadata for the resolved JDK/JVM for each toolchain.
For example, instead of registering the following custom value...
Test toolchain : JDK11
... we now register the following which includes the vendor, version,
and installation path of the JDK/JVM.
Test toolchain : AdoptOpenJDK 11 (/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home)
Once Gradle's JavaInstallationMetadata includes the exact version, we
will likely use that instead of the installation path.
See gh-25787
Prior to this commit, the Spring Framework build would rely on
setting a custom Java HOME for building all sources and tests
with that JDK.
This approach is not flexible enough, since we would be testing
the source compatibility against a recent JDK, but not a common
case experienced by the community: compiling and running
application code with a recent JDK and the official, JDK8-based
Framework artifacts.
This method is also limiting our choice of JDKs to the ones
currently supported by Gradle itself.
This commit introduces the support of Gradle JVM Toolchains in
the Spring Framework build.
We can now select a specific JDK for compiling the main
SourceSets (Java, Groovy and Kotlin) and another one for
compiling and running the test SourceSets:
`./gradlew check -PmainToolChain=8 -PtestToolchain=15`
Gradle will automatically find the JDKs present on the host or
download one automcatically. You can find out about the ones
installed on your host using:
`./gradlew -q javaToolchains`
Finally, this commit also refactors the CI infrastructure to:
* only have a single CI image (with all the supported JDKs)
* use this new feature to compile with JDK8 but test it
against JDK11 and JDK15.
Closes gh-25787
This commit introduces support for R2DBC ("Reactive Relational Database
Connectivity") with custom ConnectionFactory implementations, a
functional DatabaseClient for SQL execution, transaction management, a
bind marker abstraction database initialization utilities, and
exception translation.
Closes gh-25065
- The compiler is configured to retain compatibility with Kotlin 1.3.
- Explicit API mode is not yet enabled but could be in the future.
- A workaround for Gradle build is required for now, see
https://youtrack.jetbrains.com/issue/KT-39610 for more details.
- Some exceptions thrown by Kotlin have changed to NullPointerException,
see https://youtrack.jetbrains.com/issue/KT-22275 for more details.
Closes gh-24171
This commit ensures that the build directory exists before writing the
build scan URL to it. This is useful when the `clean` task is executed
and the build folder is gone by the time the execution is done.
See gh-22490
- Build Scan plugin is now Gradle Enterprise plugin applied in settings
- Compile task dependencies are now defined through classpath
- Test fixture publication can be disabled through public API
Closes gh-24384
This commit enables the publishing of Gradle metadata with Spring
Framework artifacts. This feature will be enabled by default with Gradle
6.0, so Spring Framework will consistently push this information in the
5.2.x generation.
Fixes gh-23503
Prior to this commit, the Spring Framework build would mix proper
framework modules (spring-* modules published to maven central) and
internal modules such as:
* "spring-framework-bom" (which publishes the Framework BOM with all
modules)
* "spring-core-coroutines" which is an internal modules for Kotlin
compilation only
This commit renames these modules so that they don't start with
"spring-*"; we're also moving the "kotlin-coroutines" module under
"spring-core", since it's merged in the resulting JAR.
See gh-23282
This commit moves the dependency management and test source files
related to integration tests to a dedicated module.
This allows us to focus the root project on building the Spring
Framework.
See gh-23282
This commit moves the existing "test sources" Gradle plugin from Groovy
to Java and updates the "buildSrc" build file to prepare for additional
plugins in the Spring Framework build.
The plugin itself looks, for a given Spring Framework module, at all the
project dependencies for the following scopes: "compile", "testCompile",
"api", "implementation" and "optional" (to be supported by a different
plugin).
See gh-23282
This commit introduces the spring-core-coroutines module
in order to avoid referencing Kotlin code from Java one,
which is currently not supported by Eclipse.
During the build, spring-core-coroutines is merged into
spring-core, so this change is expected to have no impact
for end users.
This module contains functions accessible from Java via
the CoroutinesUtils class to adapt Coroutines and Deferred
instances to and from Mono.
See gh-19975
This commit merges back the "spring-beans-groovy" module into the main
"spring-beans" one. The build is configured so:
* Java and Groovy sources are jointly compiled
* Kotlin sources are compiled after
With this change, the `MergePlugin` is not used anymore in the project
build and therefore is removed.
The `DetectSplitPackagesPlugin` wasn't applied so it's been removed as
well.

With this change, each subproject can configure its
build in a dedicated file like:
```
spring-core/spring-core.gradle
spring-web/spring-web.gradle
```

This commit adds a "spring-context-indexer" module that can be added to
any project in order to generate an index of candidate components defined
in the project.
`CandidateComponentsIndexer` is a standard annotation processor that
looks for source files with target annotations (typically `@Component`)
and references them in a `META-INF/spring.components` generated file.
Each entry in the index is the fully qualified name of a candidate
component and the comma-separated list of stereotypes that apply to that
candidate. A typical example of a stereotype is `@Component`. If a
project has a `com.example.FooService` annotated with `@Component` the
following `META-INF/spring.components` file is generated at compile time:
```
com.example.FooService=org.springframework.stereotype.Component
```
A new `@Indexed` annotation can be added on any annotation to instructs
the scanner to include a source file that contains that annotation. For
instance, `@Component` is meta-annotated with `@Indexed` now and adding
`@Indexed` to more annotation types will transparently improve the index
with additional information. This also works for interaces or parent
classes: adding `@Indexed` on a `Repository` base interface means that
the indexed can be queried for its implementation by using the fully
qualified name of the `Repository` interface.
The indexer also adds any class or interface that has a type-level
annotation from the `javax` package. This includes obviously JPA
(`@Entity` and related) but also CDI (`@Named`, `@ManagedBean`) and
servlet annotations (i.e. `@WebFilter`). These are meant to handle
cases where a component needs to identify candidates and use classpath
scanning currently.
If a `package-info.java` file exists, the package is registered using
a "package-info" stereotype.
Such files can later be reused by the `ApplicationContext` to avoid
using component scan. A global `CandidateComponentsIndex` can be easily
loaded from the current classpath using `CandidateComponentsIndexLoader`.
The core framework uses such infrastructure in two areas: to retrieve
the candidate `@Component`s and to build a default `PersistenceUnitInfo`.
Rather than scanning the classpath and using ASM to identify candidates,
the index is used if present.
As long as the include filters refer to an annotation that is directly
annotated with `@Indexed` or an assignable type that is directly
annotated with `@Indexed`, the index can be used since a dedicated entry
wil be present for that type. If any other unsupported include filter is
specified, we fallback on classpath scanning.
In case the index is incomplete or cannot be used, The
`spring.index.ignore` system property can be set to `true` or,
alternatively, in a "spring.properties" at the root of the classpath.

Move spring-webmvc-tiles3 content to spring-webmvc, and
create a spring-webmvc-tiles2 module with Tiles 2 support.
Its allows View Resolution to configure Tiles 3 instead of Tiles 2.
