如果執行 gradle clean build --info, 輸出是:

耗時是 1min 4s, 真是太長了啊 !!
觀察到, 此時執行是任務即task是:
Tasks to be executed: [task ':lkdemo-app:clean', task ':lkdemo-interface:compileJava', task ':lkdemo-interface:processResources', task ':lkdemo-interface:classes', task ':lkdemo-interface:jar', task ':lkdemo-app:compileJava', task ':lkdemo-app:processResources', task ':lkdemo-app:classes', task ':lkdemo-app:bootJar', task ':lkdemo-app:bootStartScripts', task ':lkdemo-app:bootDistTar', task ':lkdemo-ap

可以看到 有不少的 task, 其中關鍵task 是:
distZip distTar bootJar bootDistZip
最長的是 : distZip 竟然花了近 16s.. bootDistZip 花了 7s
另外, compileTestJava也花了近10s, 當然這個時間是不能少的..
而 compileTestJava 花了近13s , test 源目錄沒有幾個類, 爲什麼它這麼多? 難道是 Created classpath snapshot for incremental compilation in 0.053 secs. 1706 duplicate classes found in classpath ?
distZip 生成的 lkdemo-app-1.0.0-SNAPSHOT.zip 到底有什麼內容呢 ? 爲什麼會有這麼一個 zip ? 打開發現其中並沒有什麼特別有用的內容!
後面我又發現, 其實不用 執行 build 任務, 如果僅僅是 發佈的話, 執行 bootjar 就足夠. 此時的執行的任務是:
Tasks to be executed:[task ':lkdemo-interface:compileJava', task ':lkdemo-interface:processResources', task ':lkdemo-interface:classes', task ':lkdemo-interface:jar', task ':lkdemo-app:compileJava', task ':lkdemo-app:processResources', task ':lkdemo-app:classes', task ':lkdemo-app:bootJar']
此時的輸出是:

BUILD SUCCESSFUL in 17s
5 actionable tasks: 1 executed, 4 up-to-date
可以看到, 17s 就足夠, 快了n倍 !!
當然, 執行 jar 任務是不夠的, 因爲 對於 spring boot 項目, jar 不會執行, 從日誌可以看到:
> Task :lkdemo-app:jar SKIPPED
Skipping task ':lkdemo-app:jar' as task onlyIf is false.
如果 jar 不會執行, 那麼jar 前面的會執行嗎? 測試發現也不會...
View Code
Tasks to be executed: [task ':kl-wallet-app:clean', task ':kl-wallet-interface:compileJava', task ':kl-wallet-interface:processResources', task ':kl-wallet-interface:classes', task ':kl-wallet-interface:jar', task ':kl-wallet-app:compileJava', task ':kl-wallet-app:processResources', task ':kl-wallet-app:classes', task ':kl-wallet-app:jar']
可以對比發現, 唯一的區別是 最後一個task..
當然, 如果是普通的項目, 非spring boot 項目, jar 是會正常執行的 !!
另外發現, 即使 java 文件沒有任何變化, 還是會去掃描, 然後 也要花費 4 - 5 s 的時間..
> Task :lkdemo-interface:compileJava UP-TO-DATE
:lkdemo-interface:compileJava (Thread[Task worker for ':',5,main]) completed. Took 4.104 secs.

...
:lkdemo-app:compileJava (Thread[Task worker for ':' Thread 7,5,main]) completed. Took 5.598 secs.
怎麼辦? 使用 -x test 排查 test task, 此時的輸出是:
Tasks to be executed: [task ':kl-wallet-interface:compileJava', task ':kl-wallet-interface:processResources', task ':kl-wallet-interface:classes', task ':kl-wallet-interface:jar', task ':kl-wallet-app:compileJava', task ':kl-wallet-app:processResources', task ':kl-wallet-app:classes', task ':kl-wallet-app:bootJar']
可見, 確實沒了 test / testResource 相關的task 了, 構建更快了 !!
開心!~
