从命令行设置依赖项的版本 [英] Set the version of a dependency from command line

问题描述

我想从命令行在POM中设置依赖项的版本.与versions:set非常相似(对于项目的版本)，但是具有特定的依赖性.

I would like to set the version of a dependency in a POM from command line. Much like versions:set (for the version of the project), but for a specific dependency.

我不想制作任何XML扫描工具，因为有多种方法可以指定版本，并且很难全部处理.

I don't want to craft any XML scanning tool because there are various ways to specify a version and it is hard to handle them all.

推荐答案

如果您知道在dependency或dependencyManagement博客中指定了依赖版本，并且该版本不是属性，则可以使用

If you know your dependency versions are specified in the dependency or dependencyManagement blog and the version is not a property you can use use-dep-version:

mvn versions:use-dep-version -Dincludes=io.netty:netty-all -DdepVersion=1.0 -DforceVersion=true

但是，如果将版本指定为属性，则use-dep-version将不起作用.

However if the version is specified as a property, the use-dep-version will not work.

然后，您只能使用versions:*-property命令，但是为此您需要知道属性的名称(可以通过对这些属性使用命名约定来实现)

Then you can only use versions:*-property commands but for this you need to know the name of the property (which could be achieved by having a naming convention for these properties)

mvn versions:set-property -DnewVersion=1.0 -Dproperty=netty-all.version

如果您需要更多安全性以确保将使用的版本有效或避免降级，请查看

if you need more safety that the version you will use is valid or to avoid downgrades have a look at update-property.

如果您的项目中混有版本和属性版本，则可以只运行两个命令，一个将对其进行更改.

If you project is mixed with versions and property versions you could just run both commands and one will change it.
