This folder contains the custom plugins and conventions for the
Spring Framework build. They are declared in the
build.gradle
file in this folder.
The org.springframework.build.conventions
plugin applies
all conventions to the Framework build:
JavaConventions
KotlinConventions
TestConventions
The org.springframework.build.optional-dependencies
plugin creates a new optional
Gradle configuration - it
adds the dependencies to the project's compile and runtime classpath but
doesn't affect the classpath of dependent projects. This plugin does not
provide a provided
configuration, as the native
compileOnly
and testCompileOnly
configurations
are preferred.
This plugin uses the Gradle JApiCmp plugin to generate API Diff reports for each Spring Framework module. This plugin is applied once on the root project and creates tasks in each framework module. Unlike previous versions of this part of the build, there is no need for checking out a specific tag. The plugin will fetch the JARs we want to compare the current working version with. You can generate the reports for all modules or a single module:
./gradlew apiDiff -PbaselineVersion=5.1.0.RELEASE
./gradlew :spring-core:apiDiff -PbaselineVersion=5.1.0.RELEASE
The reports are located under
build/reports/api-diff/$OLDVERSION_to_$NEWVERSION/
.
The spring-core-test
project module contributes the
RuntimeHintsAgent
Java agent.
The RuntimeHintsAgentPlugin
Gradle plugin creates a
dedicated "runtimeHintsTest"
test task for each project.
This task will detect and execute tests
tagged with the "RuntimeHintsTests"
JUnit
tag. In the Spring Framework test suite, those are usually annotated
with the @EnabledIfRuntimeHintsAgent
annotation.
By default, the agent will instrument all classes located in the
"org.springframework"
package, as they are loaded. The
RuntimeHintsAgentExtension
allows to customize this using a
DSL:
// this applies the `RuntimeHintsAgentPlugin` to the project
{
plugins 'org.springframework.build.runtimehints-agent'
id }
// You can configure the agent to include and exclude packages from the instrumentation process.
{
runtimeHintsAgent = ["org.springframework", "io.spring"]
includedPackages = ["org.example"]
excludedPackages }
{
dependencies // to use the test infrastructure, the project should also depend on the "spring-core-test" module
testImplementation(project(":spring-core-test"))
}
With this configuration, ./gradlew runtimeHintsTest
will
run all tests instrumented by this java agent. The global
./gradlew check
task depends on
runtimeHintsTest
.
NOTE: the "spring-core-test" module doesn't shade "spring-core" by design, so the agent should never instrument code that doesn't have "spring-core" on its classpath.
