Maven 在打包罐子时无法检索构建编号

Question

我正在使用内部版本号插件为我的jar生成序列号。我将在我的CICD过程中使用它。

我遵循了网上提供的所有示例。但是，我可以得到${buildNumber}来打印它，但是在包装罐子时，我无法获得数字，我得到了${buildNumber}文本。我搜索了Maven LifeCycle，发现我需要在任何其他插件之前将其添加到验证中。但是，我仍然无法解决问题。

注意：如果我运行验证，我可以找到下面的回显消息，这意味着我可以从属性文件中正确获取数字。如果我运行包或运行，我会得到 ${artifact.id}_source-.0.1.${buildNumber}.snapshot 没有数字。

main:
[echo] current build number is "90"

我也在这里检查了这个类似的问题，并在此处和其他链接输入链接描述，但无法找出问题所在。

Answer 1

我认为这里发生的事情是Maven在构建过程开始时解析属性。

<build.number>${buildNumber}</build.number>
<model.version>${major.minor.version}.${build.number}.${build.type}</model.version>

当它解析build.number时，${buildNumber}没有值。因此，它使变量名称保持不变。我怀疑如果你修改model.version，你会遇到同样的问题：

<model.version>${major.minor.version}.${buildNumber}.${build.type}</model.version>

出于同样的原因。

您可以尝试使用本答案中所述的build-helper-maven-plugin。但是，这仍然可能不起作用，因为model.version被用作project.version的值，由于它是GAV坐标的一部分，因此很早就解决了这个问题。不过值得一试。
