我正在开发一个在 Eclipse Neon 下导入的 Maven 项目，该项目集成了 M2Eclipse 以及 Maven 的 3.3.9 版本。我的项目的源代码在 SVN 1.6 下管理（是的，我知道它很旧，但我们无法升级到 1.7 或 1.8）。
我想使用该buildnumber-maven-plugin插件从 svn 存储库中检索修订号并生成增量内部版本号，然后将它们添加到Manifest.MF.
经过一些试验和错误，pom.xml下面的内容几乎符合我的预期。事实上，一切都很好，除了 buildNumber 没有随着每次构建顺序增加。例如，每次我在源文件或pom.xml本身中进行修改时，它都会增加。而且，它并不总是每次都增加 1。我找不到它是如何或何时增加的。

有人可以告诉我这种行为的原因吗？您知道启动 buildnumber 计算的不同操作吗？有什么想法可以解决这个问题并获得一个“真正的”构建计数器（每次运行“Maven install”命令时增加 1）？
仅供参考，如果我删除检索 svn 修订号（ number1 ）的执行，这不会影响增量内部版本号的生成。
任何帮助将不胜感激！
