gradle - 在 gradle 脚本中跟踪每个任务的执行时间？

Question

在 gradle 构建脚本中跟踪任务执行时间的最优雅方法是什么？在最佳情况下，将时间直接记录到任务名称的同一行或下一行:

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

Answer 1

只是详细说明 Peter Niederwieser's answer :我们想做同样的事情，以及在结束时报告时间构建，所以缓慢的步骤是显而易见的(当他们放慢构建速度时，适当的各方会感到一种小小的但健康的羞耻感!)。

BUILD SUCCESSFUL

Total time: 1 mins 37.973 secs
Task timings:
    579ms  :myproject-foo:clean
  15184ms  :myproject-bar:clean
   2839ms  :myproject-bar:compileJava
  10157ms  :myproject-bar:jar
    456ms  :myproject-foo:compileJava
    391ms  :myproject-foo:libs
    101ms  :myproject-foo:jar
    316ms  :myproject-bar:compileTestJava
    364ms  :myproject-foo:compileTestJava
  53353ms  :myproject-foo:test
   2146ms  :myproject-bar:test
   8348ms  :www/node:npmInstall
    687ms  :www/node:npmTest

可以将类似于以下代码的内容放入顶层 build.gradle 以报告执行期间或完成后的时间。

// Log timings per task.
class TimingsListener implements TaskExecutionListener, BuildListener {
    private Clock clock
    private timings = []

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

    @Override
    void afterExecute(Task task, TaskState taskState) {
        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) {
            if (timing[0] >= 50) {
                printf "%7sms  %s\n", timing
            }
        }
    }

    @Override
    void buildStarted(Gradle gradle) {}

    @Override
    void projectsEvaluated(Gradle gradle) {}

    @Override
    void projectsLoaded(Gradle gradle) {}

    @Override
    void settingsEvaluated(Settings settings) {}
}

gradle.addListener new TimingsListener()
