#### Merging pull requests ####

Due to Guava's nature as a subset of Google's internal codebase which is
automatically synced to the public GitHub repository, we are unable to merge
pull requests directly into the master branch. Instead, once a pull request is
ready for merging, we'll make the appropriate changes in the internal codebase

  compileOptions {
    targetCompatibility(JavaVersion.VERSION_11)
    sourceCompatibility(JavaVersion.VERSION_11)
  }

  kotlinOptions {
    jvmTarget = JavaVersion.VERSION_11.toString()
  }

  // issue merging due to conflict with httpclient and something else
  packagingOptions.resources.excludes += setOf(
    "META-INF/DEPENDENCIES"
  )
}


dependencies {
  val okhttpLegacyVersion = "3.12.12"

   - Include context in the summary: what changed, why, and any issue references.
   - Use `[WIP]` for in-progress PRs to avoid premature merging or choose GitHub draft PRs.

2. **Commits**:
   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
