在Maven中丢失工件错误 [英] Missing artifact error in Maven

问题描述

在Maven构建期间，我收到一个缺失的工件错误，因为其中一个依赖关系声明它是使用该版本的属性的父工件。现在，属性本身在父pom中声明，并且我的项目的构建失败，给出了这个错误：

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}

我已经验证了工件存在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 someversion 属性在依赖pom中使用？
如果没有，应该如何更改依赖性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?

这是一个鸡和蛋问题：您无法从父级获取父级使用的版本。

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

有没有办法指定在依赖性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。您可能需要查看 MNG-624 （并投票支持）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.

如果没有，应该如何更改依赖性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.
