每次进行更改时都运行mvn软件包吗? [英] Run mvn package every time I make changes?

问题描述

首次使用docker-config.yml文件处理 DropWizard 项目使用jar文件运行服务器.

Working on a DropWizard project for the first time which uses the docker-config.yml file to run the server using the jar file.

我在终端上运行以运行服务器的命令是这样的:

The command I run on the terminal to run the server is something like this:

java -jar target/foo-0.0.1.jar server conf/docker-conf.yml

我每次更改都必须运行mvn package吗? (例如:即使是很小的更改，例如添加System.out.println()语句以调试某些内容)

Do I have to run mvn package every single time I make a change? (for eg: even a small change like adding a System.out.println() statement to debug something)

推荐答案

mvn package用于创建JAR-应用程序的可部署工件.因此，如果您真的想每次都创建JAR，是的，您需要打包所有内容.

mvn package is used to create a JAR - a deployable artifact of the application. So if you really want to create the JAR every time, yes you need to package everything.

但是，通常，如果您谈论的是诸如添加System.out.println之类的小改动，我认为您有一些正在进行的工作".在这种情况下，您可以配置IDE以使用main方法运行该类(就dropwizard框架而言，是Application类).它不会创建一个胖子罐，但是对于调试您也不是很需要.

However, usually if you’re talking about small changes like adding System.out.println I assume that you have some "work-in-progress". In this case you can configure your IDE to run the class with main method (the Application class in in terms of dropwizard framework). It won’t create a fat jar but for debugging you also don’t really need it.

这是我(而且我相信我们的许多同事)在处理由dropwizard，spring-boot(在这方面类似)等应用程序时所做的工作.

This is what I (and I believe many of our colleagues) do when working with applications powered by dropwizard, spring-boot (which is similar in this aspect), etc.
