Incremental Dex Input

[incremental_dex_input] command line tool. This tool can be used to find the correct subset of java packages to be passed for incremental dexing

Getting Started

Inputs

  • class jar, jar file containing java class files to be dexed.
  • deps file, containing the dependencies for dex.
  • dexTarget path to the output of ninja rule that triggers dex
  • outputDir, path to a output dir where dex outputs are placed

Output

  • [dexTarget].rsp file, representing list of all java packages
  • [dexTarget].inc.rsp file, representing list of java packages to be incrementally dexed
  • [dexTarget].input.pc_state.new temp state file, representing the current state of all dex sources (java class files)
  • [dexTarget].deps.pc_state.new temp state file, representing the current state of dex dependencies.

Usage

incremental_dex_input --classesJar [classJar] --dexTarget [dexTargetPath] --deps [depsRspFile] --outputDir [outputDirPath]

Notes

  • This tool internally references the core logic of [find_input_delta] tool.
  • All outputs are relative to the dexTarget path
  • Same class jar, deps, when used for different targets will output different results.
  • Once dex succeeds, the temp state files should be saved as current state files, to prepare for next iteration.
