-== Spring Framework Concourse pipeline
-
-The Spring Framework uses https://concourse-ci.org/[Concourse] for its CI build and other automated tasks.
-The Spring team has a dedicated Concourse instance available at https://ci.spring.io with a build pipeline
-for https://ci.spring.io/teams/spring-framework/pipelines/spring-framework-5.3.x[Spring Framework 5.3.x].
-
-=== Setting up your development environment
-
-If you're part of the Spring Framework project on GitHub, you can get access to CI management features.
-First, you need to go to https://ci.spring.io and install the client CLI for your platform (see bottom right of the screen).
-
-You can then login with the instance using:
-
-[source]
----
-$ fly -t spring login -n spring-framework -c https://ci.spring.io
----
-
-Once logged in, you should get something like:
-
-[source]
----
-$ fly ts
-name                  url                   team                  expiry
-spring                https://ci.spring.io  spring-framework      Wed, 25 Mar 2020 17:45:26 UTC
----
-
-=== Pipeline configuration and structure
-
-The build pipelines are described in `pipeline.yml` file.
-
-This file is listing Concourse resources, i.e. build inputs and outputs such as container images, artifact repositories, source repositories, notification services, etc.
-
-It also describes jobs (a job is a sequence of inputs, tasks and outputs); jobs are organized by groups.
-
-The `pipeline.yml` definition contains `((parameters))` which are loaded from the `parameters.yml` file or from our https://docs.cloudfoundry.org/credhub/[credhub instance].
-
-You'll find in this folder the following resources:
-
-* `pipeline.yml` the build pipeline
-* `parameters.yml` the build parameters used for the pipeline
-* `images/` holds the container images definitions used in this pipeline
-* `scripts/` holds the build scripts that ship within the CI container images
-* `tasks` contains the task definitions used in the main `pipeline.yml`
-
-=== Updating the build pipeline
-
-Updating files on the repository is not enough to update the build pipeline, as changes need to be applied.
-
-The pipeline can be deployed using the following command:
-
-[source]
----
-$ fly -t spring set-pipeline -p spring-framework-5.3.x -c ci/pipeline.yml -l ci/parameters.yml
----
-
-NOTE: This assumes that you have credhub integration configured with the appropriate secrets.

- * Apply the JVM Toolchain conventions
- * See https://docs.gradle.org/current/userguide/toolchains.html
- *
- * One can choose the toolchain to use for compiling the MAIN sources and/or compiling
- * and running the TEST sources. These options apply to Java, Kotlin and Groovy sources
- * when available.
- * {@code "./gradlew check -PmainToolchain=8 -PtestToolchain=11"} will use:
- * <ul>
- *     <li>a JDK8 toolchain for compiling the main SourceSet
- *     <li>a JDK11 toolchain for compiling and running the test SourceSet
- * </ul>
- *
- * Gradle will automatically detect JDK distributions in well-known locations.
- * The following command will list the detected JDKs on the host.
- * {@code
- * $ ./gradlew -q javaToolchains
- * }
- *
- * We can also configure ENV variables and let Gradle know about them:
- * {@code
- * $ echo JDK11
- * /opt/openjdk/java11
- * $ echo JDK15
- * /opt/openjdk/java15
- * $ ./gradlew -Dorg.gradle.java.installations.fromEnv=JDK11,JDK15 check
