java - 更新依赖项中的版本时更新模块版本(多模块 maven )

Question

我的问题:versions-maven-plugin 帮助我升级多模块 maven 项目中某些模块(我们称之为 A)的版本。

此项目中的一些模块(我们称之为B和C)具有依赖模块A。我还需要升级该模块的版本(B 和 C)。有时，我还需要升级其他模块(B-parent)中的版本，其中依赖项(A 版本升级 -> B 版本升级 -> B-parent 版本升级)。另一个问题是模块可以处于不同的嵌套级别。

示例:

root:
  ---B-parent: 
       ---B (A in dependencies)
  ---C-parent
       ---C (A in dependencies)
  ---A-parent: 
       ---A

流程:A版本升级->A-parent版本升级，C版本升级->C-parent 版本升级，B 版本升级 -> B-parent 版本升级。

这个插件无法做到这一点。

有什么想法可以做到这一点吗？ 还是我的版本更新策略不够好？

Answer 1

我制作了一个脚本，用于使用 versions-maven-plugin 递归地增加所有依赖模块中的版本号。

算法如下:

1. 运行版本:在目标模块中设置
2. 在上一步中已被 versions:set 更新的所有模块中运行 versions:set。如果模块已被处理 - 跳过它。
3. 重复步骤 2

Python 2.7 代码

#!/usr/bin/env python
# -*- coding: utf-8 -*- #

# How To
#
# Run script and pass module path as a first argument.
# Or run it without arguments in module dir.
#
# Script will request the new version number for each module.
# If no version provided - last digit will be incremented (1.0.0 -> 1.0.1).
# cd <module-path>
# <project-dir>/increment-version.py
# ...
# review changes and commit
