• Name: Desugar, transforming Java 8 bytecode to be Java 7 compatible
  Short Name: desugar
  URL: https://github.com/bazelbuild/bazel
  Version: 1.1.0
  Update Mechanism: Manual
  License: Apache-2.0
  Security Critical: no
  Shipped: yes
  
  Description:
  Desugar is a Google-developed open-source Java library used by the build process
  to transform Java 8 bytecode to Java 7. It is used to enable Java 8 features
  such as lambda experssions for Chrome on Android.
  
  Googlers: See: go/desugar
  
  Local Modifications:
  * Added BUILD.gn, proguard.flags.
  * Made all lambdas be "stateful" to avoid <clinit> bloat.
  * Desugar_deploy.jar split into Desugar.jar and Desugar_runtime.jar.
  * Desugar.jar has been run through r8.jar to remove unused .class files.
  
  Update instructions (requires @google.com account for uploading):
  * Check out Bazel from https://github.com/bazelbuild/bazel
  * Compile or install Bazel by following instructions on
      https://docs.bazel.build/versions/master/install.html
  * Apply stateful-lambdas.patch:
      git apply $CHROMIUM_SRC/third_party/bazel/desugar/stateful-lambdas.patch
  * Build Desugar_deploy.jar:
      bazel build //src/tools/android/java/com/google/devtools/build/android/desugar:Desugar_deploy.jar
  * Move Desugar_deploy.jar to location within Chromium:
      rm $CHROMIUM_SRC/third_party/bazel/desugar/Desugar.jar
      mv bazel-bin/src/tools/android/java/com/google/devtools/build/android/desugar/Desugar_deploy.jar $CHROMIUM_SRC/third_party/bazel/desugar/Desugar.jar
  * Update Desugar_runtime.jar:
      unzip Desugar.jar "com/google/devtools/build/android/desugar/runtime*"
      zip -rD0 Desugar_runtime.jar com
      rm -r com
  * Shrink via r8 (optional - reduces size by about 66%).
      java -jar ../../r8/lib/r8.jar --debug --classfile --output Desugar.new.jar --pg-conf proguard.flags --no-desugaring --lib ../../jdk/extras/java_8/jre/lib/rt.jar Desugar.jar
      mv Desugar.new.jar Desugar.jar
  * Perform a sanity check of chrome_public_apk:
      ninja chrome_public_apk
      bin/chrome_public_apk run
  * Update this README.chromium (Version)
  * Upload new jar to CIPD:
      cd third_party/bazel
      cipd create --pkg-def cipd.yaml
  * Update revision //DEPS
