The version used by protoc-gen-grpc-java will be upgraded separately,
because of large C++ build changes necessary. But that won't impact
users at all. We are upgrading to protoc 22.3; only the grpc plugin is
not upgraded.
Bazel is upgraded for both Java and C++.
Introduce an AsyncService interface in the generated code and move the methods from <service>ImplBase to default implementation of the interface.
* update pom files to allow java 1.8
* Add a bindService(<service>Async) method
* Change TestServiceImpl to use the interface and include a bind method instead of extending TestServiceImplBase.
ExpectedException is deprecated, so I fixed the new warnings. However,
we are still using ExpectedException many places and had previously
supressed the warning. See
https://github.com/grpc/grpc-java/issues/7467 . I did not fix those
existing instances that had suppressed the warning, since it is
unrelated to the upgrade and we have been free to fix them at any time
since we dropped Java 7.
This makes it more obvious when plaintext vs TLS is being used and is
the preferred API.
I did not change the Google Auth example, because it is doing things a
weird way and changing it would be more invasive. I also didn't update
the Android examples.
Oracle's Premier Support for Java 7 ended in July 2019. Per gRFC P5,
dropping support for the only release. Android is able to desugar many
Java 8 language features.
Android Gradle plugin bumped to 4.2.0 in examples, for Gradle 7 compat
and to match main build.
Jib 3 changed default base image away from distroless, but we do want
to use distroless.
Protobuf uses Guava 30.1.1, so I upgrade it at the same time. It also
caused an update to rules_jvm_external and reworking the Bazel build.
Protobuf no longer requires bind() so they were dropped. Although
Protobuf's protobuf_deps() brings in rules_jvm_external, and so we don't
need to define it ourselves, it seems better to define it directly and
not depend on transitive deps since we use it directly.
Protobuf now has support for maven_install() by exposing
PROTOBUF_MAVEN_ARTIFACTS, which required reorganizing the WORKSPACE to
use maven_install() after loading protobuf. Protobuf still doesn't
define target overrides for itself so we still maintain those. When
reorganizing the WORKSPACE I noticed http_archive should ideally be
above io_grpc_grpc_java as most users will need it there, so I fixed
that since there were lots of other load()-reordering already.
This version works around a warning about DuplicateStrategy in Gradle 6
that will be an error in Gradle 7 caused by [a bug in the plugin][1].
Bumping the version makes a clean build with `--warning-mode all` (at
least if skipping Android and codegen).

javax.annotation-api is licensed CDDL, which was not noticed when it was
introduced. Tomcat provides an Apache 2 version of the same annotation. Note
that this annotation is only used when compiling with Java 9+.
Unfortunately this may cause classpath collisions since there are _many_ copies
of this annotation on Maven Central; we wanted one canonical source and
javax.annotation-api seemed like that source. We hope this won't impact many
users since we have always suggested using it only for compilation. But it will
probably impact some users. However, we didn't create this mess, this seems to
be "standard practice" for J2EE, which this annotation is now part of, so we're
just impacted by it.
Fixes#6833
