Maven 中缺少工件错误 [英] Missing artifact error in Maven

问题描述

我在 Maven 构建期间收到缺少工件错误，因为其中一个依赖项使用版本的属性声明它是父工件.现在属性本身在父 pom 中声明，我的项目构建失败，出现此错误:

I get a missing artifact error during Maven build because one of the dependencies declares it's parent artifact using a property for the version. Now the property itself is declared in the parent pom and my project's build fails giving this error:

[ERROR] Failed to execute goal on project abc: Unable to get dependency
information for xyz:pqr:jar:SNAPSHOT: Failed to process POM for 
xyz:pqr:jar:SNAPSHOT: Non-resolvable parent POM xyz:pqr-parent:${someversion}
for xyz:pqr:${someversion}: Failed to resolve POM for 
xyz:pqr-parent:${someversion} due to Missing:
----------
1) xyz:pqr-parent:pom:${someversion}
----------
1 required artifact is missing.

for artifact:
xyz:pqr-parent:pom:${someversion}

我已验证工件位于存储库中的正确位置.

I have verified that the artifacts are present in correct location in the repository.

有没有办法指定依赖 pom 中使用的 someversion 属性的值?如果没有，应该如何更改依赖pom来解决错误?

Is there a way to specify the value of someversion property used in the dependency pom? If not, how should the dependency pom be changed to resolve the error?

这是一个先有鸡还是先有蛋的问题:您无法从父级获取要使用的父级版本.

This is a chicken and egg problem: you can't get the version of the parent to use from the parent.

有没有办法指定依赖 pom 中使用的 someversion 属性的值?

Is there a way to specify the value of someversion property used in the dependency pom?

AFAIK，这是不可能的，project.parent.version 中的属性不会被替换.您可能需要检查 MNG-624 (并为它投票)和相关问题.

AFAIK, this is not possible, properties in project.parent.version do NOT get substituted. You might want to check MNG-624 (and vote for it) and related issues.

如果不是，应该如何更改依赖pom来解决错误?

If not, how should the dependency pom be changed to resolve the error?

在 project.parent.version 中使用硬编码"版本.

Use an "hard-coded" version in project.parent.version.
