Mvnd vs Maven

原文發(fā)布于：https://nosugarcoffee.github.io/Mvnd%20vs%20Maven

介紹

Mvnd 是一個(gè)致力于提升 maven 構(gòu)建速度的項(xiàng)目。它不是一個(gè)全新的產(chǎn)物洛退，而是內(nèi)置 maven，并且整合 Gradle 和 Takari 中的優(yōu)勢(shì)技術(shù)。那么它借鑒了什么篓像？對(duì)比 maven 優(yōu)勢(shì)是否明顯谆级？適合使用在哪些場(chǎng)景温治？本文帶你一探究竟。

基本使用

安裝

Mvnd 0.7.1 運(yùn)行依賴(lài) jdk 11, 如不滿足有以下提示:

org/mvndaemon/mvnd/client/DefaultClient has been compiled by a more recent version of the Java Runtime (class file version 55.0)

推薦使用 jabba或 asdf 管理 java 多版本橄登。

觀察

執(zhí)行 mvnd 命令即可觀察到啟動(dòng)了 daemon 進(jìn)程，同時(shí)該命令也充當(dāng) client 與 daemon service 交互讥此。

執(zhí)行 mvnd --status 查看 daemon 狀態(tài)拢锹，如下展示的是一個(gè)空閑狀態(tài)的 daemon:

liangliangdai@liangliangdai-VirtualBox:~/jacoco$ /home/liangliangdai/Downloads/mvnd-0.7.1-linux-amd64/bin/mvnd --status
      ID      PID                   Address   Status    RSS            Last activity  Java home                                                                                                                               
88a359ee    69068     inet:/127.0.0.1:36633     Idle   132m  2021-12-30T12:20:43.405  /home/liangliangdai/.jabba/jdk/openjdk@1.11.0

執(zhí)行 mvnd --stop 停止 daemon。

實(shí)例測(cè)試

事先說(shuō)明

均基于 4 core linux 虛擬機(jī)
均設(shè)置 Jvm args -Xms128M Xmx2048M
Mvnd 默認(rèn)開(kāi)啟并行構(gòu)建萄喳，線程數(shù)量為 Math.max(Runtime.getRuntime().availableProcessors() - 1, 1)卒稳，為了保持一致，并行參數(shù)統(tǒng)一設(shè)置 -T 4他巨，-T 4 表示開(kāi)啟并行構(gòu)建的線程數(shù)為 4 個(gè)

從 mvnd-multi-hot 與 mvn-single 可得最優(yōu)情況下 mvnd 大約可以為此項(xiàng)目提高 20% 的構(gòu)建速度。

結(jié)論及分析

C/S 和 smart builder 是其快的原因

Mvnd 借鑒 Gradle daemon 的思想份企，使 daemon 常駐后臺(tái)也榄，構(gòu)建請(qǐng)求由 GraalVM client 轉(zhuǎn)發(fā)，得益于 classloader cache 和 JIT 的特性, 下次構(gòu)建無(wú)需重復(fù)加載已緩存的 plugin classes司志，同時(shí)熱點(diǎn)代碼信息也被記錄手蝎，更快甚至直接 JIT不像 maven 每次構(gòu)建都需要新建 jvm榕莺，故 C/S 架構(gòu)是 mvnd 構(gòu)建快的關(guān)鍵因素之一。

mvnd-multi-hot 優(yōu)于 mvnd-multi-cold 的結(jié)果棵介，很好的體現(xiàn)了 daemon 的優(yōu)勢(shì)钉鸯。

Mvnd 借鑒 Takari smart builder 的技術(shù)，相比與 maven3 并行構(gòu)建模型更優(yōu)邮辽。此為 mvnd 構(gòu)建快的另一關(guān)鍵因素唠雕。下圖展示了 maven 3 和 mvnd 并行構(gòu)建模型的區(qū)別：

image.png

mvnd-multi-cold，mvn-multi 雙方都是并行構(gòu)建且從 "cold" 啟動(dòng)吨述，mvnd 略?xún)?yōu)岩睁，故優(yōu)勢(shì)很可能來(lái)自 smart build，當(dāng)然樣本數(shù)太少揣云，不足以下定論捕儒，讀者可自行測(cè)試。

Mvnd 適合本地構(gòu)建邓夕，CI 有一定潛力

當(dāng)今主流的 CI 大多基于容器刘莹，目前 mvnd daemon 只支持來(lái)自本機(jī) client 的構(gòu)建請(qǐng)求，即各個(gè) job 所屬的容器只能利用自身啟動(dòng)的 daemon, 假如容器內(nèi)只進(jìn)行單次構(gòu)建的話那就沒(méi)那么大優(yōu)勢(shì)了焚刚，而本地構(gòu)建無(wú)此限制点弯，社區(qū)有類(lèi)似的討論。

mvnd is primarily designed for iterative development on a developer workstation. I think it is worth trying as a drop-in replacement of stock Maven. In case of issues, the users are invited to report them in the project. I see little potential for mvnd in the area of continuous integration (CI).
