如何检查pom.xml以获取更新的依赖项 [英] How to check pom.xml for updated dependencies

问题描述

我对Maven和pom.xml相当陌生.有没有一种方法可以找出我哪些依赖项已过时，从而可以更新pom.xml中的版本号.

I am fairly new to Maven and pom.xml. Is there a way I can find out which of my dependencies that are outdated, so that I can update version numbers in my pom.xml.

例如，在其他语言中，Ruby具有命令gem list outdated，该命令为我提供了我可以更新的依赖项列表(rubygems)

In other languages, for instance, Ruby has the command gem list outdated that gives me a list of dependencies (rubygems) I can update

如果可以，我正在使用IntelliJ Idea.

I am using IntelliJ Idea if that can help.

推荐答案

您可以使用版本Maven插件.检查以下目标:

You can do this with the Versions Maven Plugin. Check the following goals:

• versions:display-dependency-updates 扫描项目的依赖项并生成有关这些依赖项的报告，这些报告具有较新的版本.
• versions:display-plugin-updates 扫描项目的插件，并生成这些插件的报告，这些插件具有较新的版本.

以下是示例输出(摘自示例):

Here is a sample output (taken from the examples):

检查新的依赖更新

display-dependency-updates目标将检查项目中使用的所有依赖项，并显示这些依赖项的列表以及可用的较新版本.

Checking for new dependency updates

The display-dependency-updates goal will check all the dependencies used in your project and display a list of those dependencies with newer versions available.

以下是这种情况的一些示例:

Here are some examples of what this looks like:

svn checkout http://svn.codehaus.org/mojo/trunk/mojo/build-helper-maven-plugin build-helper-maven-plugin
cd build-helper-maven-plugin

运行

mvn versions:display-dependency-updates

哪个会产生以下输出:
