This is essentially a repeat of b118e00c, but for our compiling
documentation. Protobuf has two versions nowadays: 3.21.7 for Java and
21.7 for protobuf as a whole. For 21.1 they tagged it both as 21.1 and
3.21.1, but they didn't do that for 3.21.7.
Fixes#9582
- bump android plugin version to 4.2.0
- migrate deprecated android.support dependencies to androidx dependencies
- bump `targetSdkVersion` to 29
- temporarily ignore lint error for 'MissingClass' due to #8799
- run android CIs with `-Pandroid.useAndroidX=true -Pandroid.enableJetifier=true` flags
- android examples are still using android.support dependencies, will not be updated in this PR.
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.
These changes avoid a dependency on automake, autoconf, and libtool. The
./configure script is only available via the release artifacts, not git.
For example, on Debian Buster only curl and build-essential need to be
installed.
This mainly avoids protoc from 3.7.0 which has a dependency on libatomic. Most
of our systems have libatomic, so it mostly works, but the interop docker
container does not, so building fails. Version 3.7.1 was rebuilt to avoid
needing the libatomic shared library.
This has the added benefit that Bazel is now on the same version as Gradle, as
3.7.1 included fixes for Bazel.
For Bazel, we upgrade to protobuf 3.6.1.2 and javalite HEAD to fix
incompatibilities in newer Bazel releases.
compiler/Dockerfile is unused, so it was removed instead of being updated.
protoc no longer includes codegen for nano, so we remain on the older protoc
any time nano is used.
Protobuf now requires C++11 when compiling, so windows was swapped to
VC 14.
Also removed warnings about protoc version matching runtime, since this
is no longer supposed to be a problem (starting with 3.0.0-beta-4) and
all our tests ran fine when using protoc 3.0.2 with protobuf runtime
3.1.0.
Fixes#2316
protoc no longer builds in 3.0.0 because auto-download of the gmock zip
now fails. 3.0.2 has a fix to autogen:

All that was strictly necessary was to update .travis.yml and
buildscripts/, but it helps our sanity to keep the rest of the protobuf
versions in sync. Lite is left on its existing version, because it did
not see a bump of neither the java library nor the protoc plugin.
This allows us to play with zero-copy and proto3 support for lite.
Unfortunately, it introduced some warnings, so deprecated warnings are
now ignored for benchmarks and interop-testing.
The compilation instructions are long and scary, and they distract from
other documentation in the README. Most users don't need them, so by
moving the instructions out we improve the ease of use of the document.
