傑克編譯永遠

Question

升級我的項目以啟用Jack和Java8功能后，我的16gb macbook似乎無法構建我的項目了。 我看到內存使用量越來越高，但進程總是停留在同一點。

我的Gradle控制台：

在使用Jack之前，編譯器會在不到20秒的時間內構建，可能會出錯？ 謝謝

Answer 1

似乎這已被分類承認為“關鍵”錯誤 ，希望“2.4”Gradle插件應該為我們帶來更快的構建時間:)

並非這可能會產生重大影響，但請嘗試使用以下內容更新應用程序的build.gradle

android {
   .
   .
   .


  defaultConfig {

    .
    .
    .
    .
    jackOptions {
            enabled true
            additionalParameters('jack.incremental': 'true')
    }
    .
    .
  }

  dexOptions {
        javaMaxHeapSize '4096m'
  }

  compileOptions {
    incremental true
    .
    .
    .
  }
}

Answer 2

嘗試增加Java堆大小

  dexOptions {
    javaMaxHeapSize "4g"
  }

使用16GB的MacBook Pro，你甚至可以將它提升到8g
