The recently added body(Object) variant can be confused easily with
body(Publisher, Class) forgetting to provide the element type and
only running into the IllegalArgumentException at runtime.

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 removes JDiff from the Spring Framework build and instead,
adds a Gradle plugin that configure JApiCmp tasks on the framework
modules.
Fixes gh-22942

Add `SpringJUnit5` checkstyle rule to ensure that JUnit 4 annotations
aren't accidentally used in new tests.
The "must not be public" rule has been suppressed since there are
quite a few tests that extend base tests from other packages.
This commit migrates the spring-test test suite from JUnit 4 to JUnit
Jupiter where applicable.
Tests specific to our JUnit 4 and TestNG support remain written using
those frameworks. In addition, some tests are still written in JUnit 4
if they extend a test class that should not be migrated to JUnit
Jupiter.
See gh-23451
This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class

This commit migrates parameterized tests in spring-core using the
"composed @ParameterizedTest" approach. This approach is reused in
follow-up commits for the migration of the remaining modules.
For a concrete example, see AbstractDataBufferAllocatingTests and its
subclasses (e.g., DataBufferTests).
Specifically, AbstractDataBufferAllocatingTests declares a custom
@ParameterizedDataBufferAllocatingTest annotation that is
meta-annotated with @ParameterizedTest and
@MethodSource("org.springframework.core.io.buffer.AbstractDataBufferAllocatingTests#dataBufferFactories()").
Individual methods in concrete subclasses are then annotated with
@ParameterizedDataBufferAllocatingTest instead of @ParameterizedTest or
@Test.
The approach makes the migration from JUnit 4 to JUnit Jupiter rather
straightforward; however, there is one major downside. The arguments
for a @ParameterizedTest test method can only be accessed by the test
method itself. It is not possible to access them in an @BeforeEach
method (see https://github.com/junit-team/junit5/issues/944).
Consequently, we are forced to declare the parameters in each such
method and delegate to a custom "setup" method. Although this is a bit
cumbersome, I feel it is currently the best way to achieve fine grained
parameterized tests within our test suite without implementing a custom
TestTemplateInvocationContextProvider for each specific use case.
Once https://github.com/junit-team/junit5/issues/878 is resolved, we
should consider migrating to parameterized test classes.
See gh-23451
This first commit for this issue:
- allows JUnit Jupiter to be used for all tests
- adds a dependency on mockito-junit-jupiter
- migrates tests in spring-core to JUnit Jupiter, except parameterized
tests
The following script was developed in order to semi-automate the
migration process.

This commit removes unused parts of the Gradle build:
* Gradle wrapper customization which should not be needed in recent
versions of Gradle (or can be replaced with options in the
gradle.properties file)
* the branch strategy configuration
See gh-23282
This commit moves the compile configuration from the Gradle DSL to a
convention. This configuration is not changing often, and we're using
that opportunity to make the Java source compatibility a project
property so as to easily recent JDKs this on the command line.
See gh-23282
ClassLoaderAwareUndeclaredThrowableStrategy fails with a VerifyError on recent JDKs after the CGLIB 3.3 upgrade. The alternative is to replace it with a plain ClassLoaderAwareGeneratorStrategy (extracted from CglibSubclassingInstantiationStrategy) and custom UndeclaredThrowableException handling in CglibMethodInvocation.
See gh-23453
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
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 Kotlin code snippets, for now
in the core reference documentation. Other sections
will follow, as well as improvements like global
language switch.
