How to update pom version and dependency version using maven
问题
我有多个Java Maven项目，它们托管为服务。
一个项目是通用的jar，被添加为其他服务的依赖项。
现在，我需要在每次构建后更新pom中的版本，并且相同的版本需要更新到其他服务中。我正在使用Jenkins作为构建工具。
我检查了快照，但似乎已被弃用。请提供替代方案。
英文:
I have multiple Java maven projects that are hosted as Services
One project is common jar that is added as dependency in other services
Now, I need to update version in pom after each build and same version needs to be updated in other services. I am using Jenkins as build tool
I checked for snapshot but it seems to be deprecated. Please help with alternative

为了自动更新依赖项目中的版本，您可以使用Maven Versions插件。该插件提供了用于更新项目及其依赖项版本的目标。
以下是更新公共jar项目版本并将相同版本传播到其他依赖项目的步骤：
将Maven Versions插件添加到您的公共jar项目的pom.xml文件中：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>2.7</version>
</plugin>
</plugins>
</build>
在公共jar项目的Jenkins构建作业中，使用以下Maven命令来更新项目版本：
mvn versions:set -DnewVersion=<new_version>
将<new_version>替换为您要设置的新版本。
在公共jar项目构建并更新其版本后，您可以使用以下Maven命令来更新其他服务中的公共jar依赖项的版本：
mvn versions:update-parent
此命令将更新依赖项目的父版本以匹配公共jar项目的新版本。
最后，您可以使用更新后的公共jar依赖项构建依赖项目。
通过使用Maven Versions插件和上述步骤，您可以自动化更新Jenkins构建作业中的公共jar项目及其依赖项的版本过程。
英文:
To automatically update the version in the dependent projects, you can use the Maven Versions plugin. This plugin provides goals to update the version of the project and its dependencies.
Here are the steps to update the version of the common jar project and propagate the same version to other dependent projects:
Add the Maven Versions plugin to your common jar project's pom.xml file:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>2.7</version>
</plugin>
</plugins>
</build>
In the Jenkins build job for the common jar project, use the following Maven command to update the project version:
mvn versions:set -DnewVersion=<new_version>
Replace <new_version> with the new version you want to set.
After the common jar project is built and its version is updated, you can use the following Maven command to update the version of the common jar dependency in your other services:
mvn versions:update-parent
This command will update the parent version of the dependent projects to match the new version of the common jar project.
Finally, you can build the dependent projects with the updated version of the common jar dependency.
By using the Maven Versions plugin and the above steps, you can automate the process of updating the version of the common jar project and its dependencies in your Jenkins build job.
