Release 0.17.1rc1 (2018-08-23)
Baseline: aa118ca818baf722aede0bc48d0a17584fa45b6e
Incompatible changes:
- Loading @bazel_tools//tools/build_defs/repo:git_repositories.bzl no longer works. Load @bazel_tools//tools/build_defs/repo:git.bzl instead.
- If the same artifact is generated by two distinct but identical actions, and a downstream action has both those actions' outputs in its inputs, the artifact will now appear twice in the downstream action's inputs. If this causes problems in Skylark actions, you can use the uniquify=True argument in Args.add_args.

- Labels in C++ rules' linkopts attribute are not expanded anymore unless they are wrapped, e.g: $(location //foo:bar)

- New bazelrc file list.
- Windows: when BAZEL_SH envvar is not defined and Bazel searches for a suitable bash.exe, Bazel will no longer look for Git Bash and no longer recommend installing it as a Bash implementation. See issue #5751.
- New bazelrc file list.
New features:
- The aquery command now supports --output=text.
- Java, runfiles: the Java runfiles library is now in @bazel_tools//tools/java/runfiles. The old target (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and will be removed in Bazel 0.18.0.
- Java, runfiles: the Java runfiles library is now in @bazel_tools//tools/java/runfiles. The old target (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and will be removed in Bazel 0.19.0 (not 0.18.0, as stated earlier).
Important changes:
- Allow @ in package names.
- Remove support for java_runtime_suite; use alias() together with select() instead.
- Python wrapper scripts for MSVC are removed.
- [JavaInfo] Outputs are merged in java_common.merge().
- Faster analysis by improved parallelization.
- --experimental_shortened_obj_file_path is removed.
- Introduce the --remote_cache_proxy flag, which allows for remote http caching to connect via a unix domain socket.
- No longer define G3_VERSION_INFO for c++ linkstamp compiles, as it was a duplicate of G3_TARGET_NAME.
- Added support for Android NDK r17. The default STL is now
libc++, and support for targeting mips, mips64 and ARMv5 (armeabi) has been removed.
- Add aquery command to get analysis time information about the action graph.
- Fixed compatibility with aar_import when using aapt2. AAPT2 is now supported for Android app builds without resource shrinking. To use it, pass the
--android_aapt=aapt2 flag or define android_binary.aapt_version=aapt2.
- Code coverage is collected for Java binaries invoked from sh_test.
- java_common.compile creates the native headers jar accesible via JavaInfo.outputs.native_headers.
- Deleting deprecated no-op flag --show_package_location
- The JDK shipped with Bazel was updated to JDK10.
- Rename the startup flag --host_javabase to --server_javabase to avoid confusion with the build flag --host_javabase
- newly added options --experimental_repository_hash_file and --experimental_verify_repository_rules allow to verify for repositories the directory generated against pre-recorded hashes. See documentation for those options.
- Removed the gen_jars output group
- --subcommands can now take a "pretty_print" value ("--subcommands=pretty_print") to print the arguments of subcommands as a list for easier reading.
- follow-up to https://github.com/bazelbuild/bazel/commit/1ac359743176e659e9c7472 645e3142f3c44b9e8
- A rule error is now thrown if a Skylark rule implementation function returns multiple providers of the same type.
- When using Bazel's remote execution feature and Bazel has to fallback to local execution for an action, Bazel used non-sandboxed local execution until now. From this release on, you can use the new flag --remote_local_fallback_strategy= to tell Bazel which strategy to use in that case.
- Execution Log Parser can now, when printing it out, filter the log by runner type
- A rule error is now thrown if a Skylark rule implementation function returns multiple providers of the same type.
- Removed the gen_jars output group
- Removed the gen_jars output group
- Set --defer_param_files to default to true.
- Sort attribute lists in proto-form query output to fix non-deterministic genquery output.
- Replace 0/1 with False/True for testonly attribute
- bazel now supports a .bazelignore file specifying directories to be ignored; however, these directories still have to be well founded and, in particular, may not contain symlink cycles.
- Add more detailed reporting of the differences between startup options.
- update data binding to 3.2.0
- For Android incremental dexing actions, Bazel now persists its DexBuilder process across individual actions. From our benchmarks, this results in a 1.2x speedup for clean local builds.
- The standard
xcode_VERSION feature now always uses exactly two components in the version, even if you specify --xcode_version with more or fewer than two.
- A rule error will be thrown if a Skylark rule implementation function returns multiple providers of the same type. Try the
--incompatible_disallow_conflicting_providers flag to ensure your code is forward-compatible.
- Removed notion of FULLY_STATIC linking mode from C++ rules.
- In documentation, we've renamed Skylark into Starlark.
- Execution Log Parser can now, when printing it out, reorder the actions for easier text diffs
- Linkstamps are no longer recompiled after server restart.
- Use VanillaJavaBuilder and disable header compilation in toolchain_hostjdk8. The default toolchain will soon drop compatibility with JDK 8. Using a JDK 8 host_javabase will only be supported when using 'VanillaJavaBuilder' (which does not support Error Prone, Strict Java Deps, or reduced classpaths) and with header compilation disabled.
Notice: Bazel installers contain binaries licensed under the GPLv2 with Classpath exception. Those installers should always be redistributed along with the source code.
Some versions of Bazel contain a bundled version of OpenJDK. The license of the bundled OpenJDK and other open-source components can be displayed by running the command bazel license. The vendor and version information of the bundled OpenJDK can be displayed by running the command bazel info java-runtime. The binaries and source-code of the bundled OpenJDK can be downloaded from our mirror server.
Security: All our binaries are signed with our public key 48457EE0.
