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.

Spring Framework Build
This folder contains the custom plugins and conventions for the Spring Framework build.
They are declared in the build.gradle
file in this folder.
Build Conventions
Compiler conventions
The org.springframework.build.compile
plugin applies the Java compiler conventions to the build.
Build Plugins
Optional dependencies
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.
API Diff
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/
.
