JAR部署后自动更新Maven依赖项 [英] Automatically update Maven dependencies after JAR deployment

问题描述

我有一个Java Maven项目，在POM.xml文件中定义了一些依赖项. 这些依赖项通常每个月都有较新的版本，因此我想部署一个JAR文件，该文件可以在每次启动时自动检查这些依赖项的最新版本(而无需重新构建Java Maven项目).

I have a Java Maven project with some dependencies defined in the POM.xml file. These dependencies often have newer versions every month, so I would like to deploy a JAR file that automatically checks the latest versions of those dependencies in each startup (without re-building the Java Maven project).

是否可以使用Maven做到这一点?

Is it possible to achieve that with Maven?

我知道版本Maven插件对于下载最新版本的Maven插件很有用.依赖关系，但仅当重建"项目时(不在部署的JAR中).我也知道我可以使用像这样的表达式:

I know that the Versions Maven Plugin is useful to download the latest versions of dependencies, but only when "re-building" the project (not in a deployed JAR). I also know that I can use expressions like:

<version>[1.8,]</version>

但是，同样，这些依赖项仅在构建项目后才下载.我想在用户每次启动应用程序时自动更新依赖项.

But, again, these dependencies are only downloaded after building the project. I want to update dependencies automatically every time the user launches the application.

更新:

我要自动更新的依赖项是"selenium-chrome-driver".我的应用程序使用Chrome驱动程序来启动Google Chrome浏览器.

The dependency I want to automatically be updated is "selenium-chrome-driver". My application uses Chrome Driver to launch the Google Chrome browser.

问题是Chrome驱动程序每隔几个月更新一次，而旧版本则过时".结果，几个月后，已部署的JAR尝试使用旧版的Chrome驱动程序启动浏览器，但该浏览器无法正常工作.因此，我需要自动更新此依赖关系.否则，我将不得不每X个月部署一个新的JAR.

The problem is that Chrome Driver is updated every few months, and the older versions become "outdated". As a result, after a few months, the deployed JAR tries to launch the browser with an older version of Chrome Driver and it doesn't work. For that reason, I need to automatically update this dependency. Otherwise, I would have to deploy a new JAR every X months.

推荐答案

多年来我一直遇到相同的问题，有一个库可以做到这一点， https://github.com/bonigarcia/webdrivermanager ，但我没有亲自尝试

I had same problem for years, there is a library to do this, https://github.com/bonigarcia/webdrivermanager , but I didn't try it myself

当前正在使用此脚本(ubuntu)

Currently am using this script (ubuntu)

# This script checks & downloads latest chromeDriver and geckoDriver IF needed.
# New drivers are extracted and copied to $driversDestination
# IMPORTANT: Remember to change $driversDestination variable below to match your case
# You can call this script before launching your test suite so you always get latest drivers each run

os=linux64
driversDestination=../dependencies/browser-drivers/

if [ -e chromedriver_last.txt ]
then
    chromedriver_last_download=`cat chromedriver_last.txt`
