Closes #11017. Test Plan: 1. Create java_tools from this commit: $ bazel build src:java_tools_java14.zip 2. Switch to using the java_tools from the above step in WORKSPACE file: load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive") http_archive( name = "remote_java_tools_linux", urls = [ "file:///<path to the java_tools_java14.zip>", ], ) 3. Add Zulu OpenJDK14 to use as javabase in WORKSPACE file: http_archive( name = "openjdk14_linux_archive", build_file_content = """ java_runtime(name = 'runtime', srcs = glob(['**']), visibility = ['//visibility:public']) exports_files(["WORKSPACE"], visibility = ["//visibility:public"]) """, sha256 = "48bb8947034cd079ad1ef83335e7634db4b12a26743a0dc314b6b861480777aa", strip_prefix = "zulu14.28.21-ca-jdk14.0.1-linux_x64", urls = ["https://cdn.azul.com/zulu/bin/zulu14.28.21-ca-jdk14.0.1-linux_x64.tar.gz"], ) 4. Activate custom java toolchain and javabase in .bazelrc file: build --java_toolchain=@remote_java_tools_linux//:toolchain_jdk_14 build --host_java_toolchain=@remote_java_tools_linux//:toolchain_jdk_14 build --javabase=@openjdk14_linux_archive//:runtime build --host_javabase=@openjdk14_linux_archive//:runtime 5. Create Java 14 example class file: public class Javac14Example { record Point(int x, int y) {} public static void main(String[] args) { Point point = new Point(0, 1); System.out.println(point.x); } } 6. Add Bazel file to build Java 14 syntax class with activated preview features: java_binary( name = "Javac14Example", srcs = ["Javac14Example.java"], javacopts = ["--enable-preview"], jvm_flags = ["--enable-preview"], main_class = "Javac14Example", ) 7. Test that it works as expected: $ bazel run java:Javac14Example INFO: Analyzed target //java:Javac14Example (1 packages loaded, 2 targets configured). INFO: Found 1 target... INFO: From Building java/Javac14Example.jar (1 source file): Note: java/Javac14Example.java uses preview language features. Note: Recompile with -Xlint:preview for details. Target //java:Javac14Example up-to-date: bazel-bin/java/Javac14Example.jar bazel-bin/java/Javac14Example INFO: Elapsed time: 1.502s, Critical Path: 1.30s INFO: 1 process: 1 worker.
