incompatible_use_toolchain_providers_in_java_common: pass JavaToolchainInfo and JavaRuntimeInfo providers to java_common APIs instead of configured targets

[cushon]

The option --incompatible_use_toolchain_providers_in_java_common makes java_toolchain and host_javabase APIs in java_common accept the java_common.JavaToolchainInfo and java_common.JavaRuntimeInfo providers instead of configured targets.

This change is being made in preparation for migrating the Java to use Toolchain Resolution (#4592).

Migration Notes

Update all java_common APIs with the parameters java_toolchain or host_javabase to use the find_java_runtime_toolchain and find_java_toolchain utilities:

+@load("@bazel_tools//tools/jdk:toolchain_utils.bzl", "find_java_runtime_toolchain", "find_java_toolchain")

java_common.compile(
  ...,
-  java_toolchain = ctx.attr._java_toolchain,
-  host_javabase = ctx.attr._host_javabase,
+  java_toolchain = find_java_toolchain(ctx, ctx.attr._java_toolchain),
+  host_javabase = find_java_runtime_toolchain(ctx, ctx.attr._host_javabase),
)

The ctx and java_toolchain_attr parameters of java_common.default_javac_opts have been replaced with java_toolchain:

+@load("@bazel_tools//tools/jdk:toolchain_utils.bzl", "find_java_toolchain")

javacopts = java_common.default_javac_opts(
-    ctx,
-    java_toolchain_attr = "_java_toolchain",
+    find_java_toolchain(ctx, ctx.attr._java_toolchain),
)

Is this already available? Asking since I’m planning on moving rules_scala to new java_common and JavaInfo APIs and would rather not have another round later

It isn't available yet. Support for passing providers instead of targets will probably make it into 0.23, and support for passing targets will be removed some time that after.
