David Pursehouse 72ae089206 Fix NarrowingCompoundAssignment warnings from Error Prone
Error Prone reports:

  [NarrowingCompoundAssignment] Compound assignments from long to int
  hide lossy casts

and

  [NarrowingCompoundAssignment] Compound assignments from int to byte
  hide lossy casts

  See https://errorprone.info/bugpattern/NarrowingCompoundAssignment

Fix the warnings by adding explicit casts or changing types as
necessary.

Now that all occurrences of the warning are fixed, increase its
severity to ERROR.

David Pursehouse dad9e1ff95 GlobalBundleCache: Fix ClassNewInstance warning from Error Prone
Error Prone reports:

  [ClassNewInstance] Class.newInstance() bypasses exception checking;
  prefer getDeclaredConstructor().newInstance()

  See https://errorprone.info/bugpattern/ClassNewInstance

This was the only occurrence of the warning in the code base; now it's
fixed, increase the severity to ERROR to prevent future occurrences.

David Pursehouse 430be89307 Error Prone: Increase severity of NonOverridingEquals to ERROR
Error Prone reports the warning on several classes:

   [NonOverridingEquals] equals method doesn't override Object.equals;
   if this is a type-specific helper for a method that does override
   Object.equals, either inline it into the callers or rename it to
   avoid ambiguity.

   See https://errorprone.info/bugpattern/NonOverridingEquals

Most of these are in the public API, so we can't rename or inline them
without breaking the API. FileSnapshot is not part of the public API,
but clients may be using it anyway, so we also shouldn't change that.

Suppress all the warnings instead. Having the check at severity ERROR
will at least make sure we don't introduce any new occurrences.

David Pursehouse 245c2c09a0 Bazel: Increase severity of most error-prone checks to ERROR
Most of the checks can be increased to ERROR because there is no
code in the project that triggers them.

There are still several that are triggered, and these are left
at the WARN severity:

  https://errorprone.info/bugpattern/AmbiguousMethodReference
  https://errorprone.info/bugpattern/BadComparable
  https://errorprone.info/bugpattern/ClassNewInstance
  https://errorprone.info/bugpattern/Finally
  https://errorprone.info/bugpattern/FutureReturnValueIgnored
  https://errorprone.info/bugpattern/ImmutableEnumChecker
  https://errorprone.info/bugpattern/NarrowingCompoundAssignment
  https://errorprone.info/bugpattern/NonOverridingEquals
  https://errorprone.info/bugpattern/OperatorPrecedence
  https://errorprone.info/bugpattern/ReferenceEquality
  https://errorprone.info/bugpattern/ShortCircuitBoolean
  https://errorprone.info/bugpattern/StringEquality
  https://errorprone.info/bugpattern/TypeParameterUnusedInFormals

These can be cleaned up and increased to ERROR in follow-up
commits.

David Pursehouse 4c33f70d5a Enable error-prone checks by default
Based on recent work by Dave Borowitz on the Gerrit project [1, 2].

The warnings/error configuration is unchanged, but now the checks are
enabled by default during the build rather than having to be manually
invoked.

Also replace native git_repository rule with Starlark rule. This is
needed because in recent Bazel versions native git_repository rule
is deprecated.

David Ostrovsky 7d89f0a053 Bazel: Provide toolchain with activated error prone warnings
On recent bazel versions it's trivial to apply package specific checks.
Provide custom java toolchain with all error prone warnings activated.

The list of all error prone warnings was borrowed from here: [1].

Test Plan:

  $ bazel build --java_toolchain //tools:error_prone_warnings_toolchain \
    //...

David Ostrovsky e92a0c3adc Implement initial framework of Bazel build
The initial implementation only builds the packages consumed by
Gerrit Code Review.

Test build and execution is not implemented.

We prefer to consume maven_jar custom rule from bazlets repository,
for the same reasons as in the Gerrit project:

* Caching artifacts across different clones and projects
* Exposing source classifiers and neverlink artifact

TEST PLAN:

  $ bazel build :all
  $ unzip -t bazel-genfiles/all.zip
  Archive: bazel-genfiles/all.zip
    testing: libjgit-archive.jar      OK
    testing: libjgit-servlet.jar      OK
    testing: libjgit.jar              OK
    testing: libjunit.jar             OK
  No errors detected in compressed data of bazel-genfiles/all.zip.
