java Maven在打包jar时无法检索buildNumber

Question

我正在使用buildnumber maven插件为我的jar生成序列号。我将在CICD过程中使用它

我遵循了网上所有的例子。但是，我可以得到${buildNumber}来打印它，但是在打包jar时，我不能得到这个数字，我得到了${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。但我还是不能解决这个问题

注意：如果我运行validate，我可以在下面找到echo消息，这意味着我可以从属性文件中正确地获取数字。如果我运行包或运行，我得到${artifact.id}\u source-.0.1${buildNumber}。没有数字的快照

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

我也检查了这个类似的问题here&enter link description here和其他链接，但无法解决问题

Answer 1

我认为这里发生的是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，它保持变量名不变。如果你把model.version修改成这样，我怀疑你也会遇到同样的问题：

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

出于同样的原因

您可以尝试使用this answer中描述的build-helper-maven-plugin。但是，这可能仍然不起作用，因为model.version被用作project.version的值，它很早就被解析为GAV坐标的一部分。不过值得一试
