跟蹤gradle腳本中每個任務的執行時間？

Question

跟蹤Gradle構建腳本中任務花費多長時間的最優雅方式是什麼？在最佳的情況下登錄時直接相同或下一行的任務名稱

:buildSrc:testClasses (0.518 secs) 
:fooBar (28.652 secs) 

Answer 1

最簡潔的解決方案是實現一個TaskExecutionListener（我相信你能處理的部分），並與gradle.taskGraph.addTaskExecutionListener註冊。

Answer 2

只是想詳細說明另一個答案：我們想做同樣的事情，並在 構建結束時報告時間，所以緩慢的步驟是顯而易見的（適當的各方感覺到一小部分但健康的恥辱，當他們放慢建設！）。

    private timings = [] 

    @Override 
    void beforeExecute(Task task) { 
     clock = new org.gradle.util.Clock() 
    }

     def ms = clock.timeInMs 
     timings.add([ms, task.path]) 
     task.project.logger.warn "${task.path} took ${ms}ms" 
    } 

    @Override 
    void buildFinished(BuildResult result) { 
     println "Task timings:" 
     for (timing in timings) {

    @Override 
    void settingsEvaluated(Settings settings) {} 
} 

gradle.addListener new TimingsListener() 

Answer 3

我知道這是一個古老的問題，但我發現一個很酷的插件，可以完成任務計時。這就像@jlevy答案，但有更多的選項可用：https://github.com/passy/build-time-tracker-plugin

Pascal Hartig的這個插件不斷記錄您的構建時間，並提供CSV和條形圖摘要。開發人員推薦它隨着時間的推移監控您的構建時間，而--profile則爲您提供當前構建的快照。

這是我目前如何使用它：

buildscript { 
    repositories { 
     mavenCentral() 
    } 

    dependencies { 
     classpath "net.rdrei.android.buildtimetracker:gradle-plugin:0.7.+" 
    } 
} 

apply plugin: "build-time-tracker" 

buildtimetracker { 
    reporters { 
     summary { 
      ordered false 
      threshold 50 
      barstyle 'unicode' 
     } 
    } 
} 

Answer 4

這是已被修改，刪除公開訪問gradle這個Clock類，它已被否決的用法jlevy's answer above的變化。
