+// This script adds support for the following two JVM system properties
+// that control the build for alternative JDKs (i.e., a JDK other than
+// the one used to launch the Gradle process).
+//
+// - customJavaHome: absolute path to the alternate JDK installation to
+//     use to compile Java code and execute tests. This system property
+//     is also used in spring-oxm.gradle to determine whether JiBX is
+//     supported.
+//
+// - customJavaSourceVersion: Java version supplied to the `--release`
+//     command line flag to control the Java source and target
+//     compatibility version. Supported versions include 9 or higher.
+//     Do not set this system property if Java 8 should be used.
+//
+// Examples:
+//
+// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
+//
+// ./gradlew --no-build-cache -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
+//
+// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home -DcustomJavaSourceVersion=14 test

- * 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>
- *
- * By default, the build will fall back to using the current JDK and 17 language level for all sourceSets.
- *
- * 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 -Porg.gradle.java.installations.fromEnv=JDK11,JDK15 check
- * }

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-The following instructions have been tested against [STS](https://spring.io/tools) 4.12.0
-([download](https://github.com/spring-projects/sts4/wiki/Previous-Versions#spring-tools-4120-changelog))

+The following instructions have been tested against [STS](https://spring.io/tools) 4.3.2
+([download](https://github.com/spring-projects/sts4/wiki/Previous-Versions#spring-tools-432-changelog))
+(based on Eclipse 4.12) with [Eclipse Buildship](https://projects.eclipse.org/projects/tools.buildship).
 The instructions should work with the latest Eclipse distribution as long as you install
 [Buildship](https://marketplace.eclipse.org/content/buildship-gradle-integration). Note
 that STS 4 comes with Buildship preinstalled.

-If you are using Eclipse 4.21, you will need to install
-[Java 17 Support for Eclipse 2021-09 (4.21)](https://marketplace.eclipse.org/content/java-17-support-eclipse-2021-09-421)
-from the Eclipse Marketplace.
-
 ## Steps

 _When instructed to execute `./gradlew` from the command line, be sure to execute it within your locally cloned `spring-framework` working directory._

-1. Install the [Groovy Development Tools](https://marketplace.eclipse.org/content/groovy-development-tools).
-   - **NOTE**: As of October 12, 2021, the Groovy Development Tools do not work in Eclipse 2021-09 (4.21). See [Groovy Eclipse #1303](https://github.com/groovy/groovy-eclipse/issues/1303) for details.
-1. Switch to Groovy 3.0 in Eclipse (Preferences &#8594; Groovy &#8594; Compiler &#8594; Switch to 3.0...).
-   - If you encounter build errors stating something similar to _"Groovy: compiler mismatch: project level is 2.5, workspace level is 3.0"_, change the Groovy compiler version to 3.0 for each affected project.
-1. Ensure that the _Forbidden reference (access rule)_ in Eclipse is set to `Info`
-(Preferences &#8594; Java &#8594; Compiler &#8594; Errors/Warnings &#8594; Deprecated and restricted API &#8594; Forbidden reference (access rule)).
-1. Optionally install the [Kotlin Plugin for Eclipse](https://marketplace.eclipse.org/content/kotlin-plugin-eclipse) if you need to execute Kotlin-based tests or develop Kotlin extensions.
-   - **NOTE**: As of September 21, 2021, it appears that the Kotlin Plugin for Eclipse does not yet work with Eclipse 4.21.
-1. Optionally install the [AspectJ Development Tools](https://marketplace.eclipse.org/content/aspectj-development-tools) (_AJDT_) if you need to work with the `spring-aspects` project.
-   - **NOTE**: As of September 21, 2021, it appears that the AspectJ Development Tools do not yet work with Eclipse 4.21.
-1. Optionally install the [TestNG plugin](https://testng.org/doc/eclipse.html) in Eclipse if you need to execute individual TestNG test classes or tests in the `spring-test` module.
-   - As an alternative to installing the TestNG plugin, you can execute the `org.springframework.test.context.testng.TestNGTestSuite` class as a "JUnit 5" test class in Eclipse.
+1. Ensure that Eclipse launches with JDK 8.
+   - For example, on Mac OS this can be configured in the `Info.plist` file located in the `Contents` folder of the installed Eclipse or STS application (e.g., the `Eclipse.app` file).
+1. Install the [Kotlin Plugin for Eclipse](https://marketplace.eclipse.org/content/kotlin-plugin-eclipse) in Eclipse.
+1. Install the [Eclipse Groovy Development Tools](https://github.com/groovy/groovy-eclipse/wiki) in Eclipse.
+1. Switch to Groovy 2.5 (Preferences -> Groovy -> Compiler -> Switch to 2.5...) in Eclipse.
+1. Change the _Forbidden reference (access rule)_ in Eclipse from Error to Warning
+(Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rule)).
+1. Optionally install the [AspectJ Development Tools](https://marketplace.eclipse.org/content/aspectj-development-tools) (_AJDT_) if you need to work with the `spring-aspects` project. The AspectJ Development Tools available in the Eclipse Marketplace have been tested with these instructions using STS 4.5 (Eclipse 4.14).
+1. Optionally install the [TestNG plugin](https://testng.org/doc/eclipse.html) in Eclipse if you need to execute TestNG tests in the `spring-test` module.
 1. Build `spring-oxm` from the command line with `./gradlew :spring-oxm:check`.
-1. To apply Spring Framework specific settings, run `./gradlew cleanEclipse eclipse` from the command line.
-1. Import all projects into Eclipse (File &#8594; Import &#8594; Gradle &#8594; Existing Gradle Project &#8594; Navigate to the locally cloned `spring-framework` directory &#8594; Select Finish).
+1. To apply project specific settings, run `./gradlew eclipseBuildship` from the command line.
+1. Import into Eclipse (File -> Import -> Gradle -> Existing Gradle Project -> Navigate to the locally cloned `spring-framework` directory -> Select Finish).
   - If you have not installed AJDT, exclude the `spring-aspects` project from the import, if prompted, or close it after the import.
-   - If you run into errors during the import, you may need to set the _Java home_ for Gradle Buildship to the location of your JDK 8 installation in Eclipse (Preferences &#8594; Gradle &#8594; Java home).
-1. If you need to execute JAXB-related tests in the `spring-oxm` project and wish to have the generated sources available, add the `build/generated-sources/jaxb` folder to the build path (right click on the `jaxb` folder and select "Build Path &#8594; Use as Source Folder").
-   - If you do not see the `build` folder in the `spring-oxm` project, ensure that the "Gradle build folder" is not filtered out from the view. This setting is available under "Filters" in the configuration of the Package Explorer (available by clicking on the _three vertical dots_ in the upper right corner of the Package Explorer).
+   - If you run into errors during the import, you may need to set the _Java home_ for Gradle Buildship to the location of your JDK 8 installation in Eclipse (Preferences -> Gradle -> Java home).
+1. If you need to execute JAXB-related tests in the `spring-oxm` project and wish to have the generated sources available, add the `build/generated-sources/jaxb` folder to the build path (right click on the `jaxb` folder and select `Build Path -> Use as Source Folder`).

This setting is available under "Filters" in the configuration of the Package Explorer (available by clicking on the small downward facing arrow in the upper right corner of the Package Explorer).
 1. Code away!

 ## Known Issues

-1. `spring-core` should be pre-compiled due to repackaged dependencies.
-   - See `*RepackJar` tasks in the `spring-core.gradle` build file.
-1. `spring-oxm` should be pre-compiled due to JAXB types generated for tests.
-   - Note that executing `./gradlew :spring-oxm:check` as explained in the _Steps_ above will compile `spring-core` and generate JAXB types for `spring-oxm`.
+1. `spring-core` and `spring-oxm` should be pre-compiled due to repackaged dependencies.
+   - See `*RepackJar` tasks in the build.
 1. `spring-aspects` does not compile due to references to aspect types unknown to Eclipse.
   - If you installed _AJDT_ into Eclipse it should work.
 1. While JUnit tests pass from the command line with Gradle, some may fail when run from
