Maven：在依赖性分类器中使用继承属性会导致构建失败 [英] Maven: Using inherited property in dependency classifier causes build failure

问题描述

给出三个POM文件：

• C取决于B。


• B继承自A 。


• 我可以构建A和B


• C因为依赖于B而无法构建。

• C depends on B.
• B inherits from A.
• I can build A and B
• C fails to build because of its dependency on B.

完整的源代码和构建输出包含在下面供您查看。

The full source-code and build output is included below for your review.

这是A的POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            </properties>
        </profile>
    </profiles>
</project>

这是B的POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            </properties>
        </profile>
    </profiles>
</project>

这是C的POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <name>C</name>
    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>B</artifactId>
            <version>${project.version}</version>
        </dependency>
    </dependencies>
</project>

以下是C的构建输出：

我知道这个问题与 https://issues.apache.org/jira/browse/MNG-3228 但我不确定如何修复它。请帮助！

I know this issue is related to https://issues.apache.org/jira/browse/MNG-3228 but I'm not sure how to fix it. Please help!

更新：

向B添加分类器有帮助。现在C构建只要存储库只包含B的jar文件。如果我将B的POM文件与存储库中的JAR一起上传，则C会因上述错误（ $ {swt.classifier }未定义）而失败。任何想法？

Adding a classifier to B helped. Now C builds so long as the repository only contains B's jar file. If I upload B's POM file alongside the JAR in the repository, C fails with the aforementioned error (${swt.classifier} not defined). Any ideas?

推荐答案

从Maven 3.1.0开始，这是不可能的。以下是相关功能请求： https://issues.apache.org/jira/browse/ MNG-1388

This isn't possible as of Maven 3.1.0. Here is the relevant feature request: https://issues.apache.org/jira/browse/MNG-1388
