tl; dr： mvn clean install按预期工作，但 Jenkins 无法解析子 pom 中的变量。
我们有一个包含一个主 pom 和多个子 pom 的项目。它似乎在 sub pom 中失败，变量${project.version}没有被解析（请参阅下面的错误消息并滚动到其末尾）。
主要的pom：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>group</groupId>
<artifactId>artifact</artifactId>
<version>1.0.0.0-SNAPSHOT</version>
...
</project>
子pom：
<parent>
<groupId>group</groupId>
<artifactId>artifact</artifactId>
<version>${project.version}</version>
<relativePath>../pom.xml</relativePath>
</parent>
mvn clean install在控制台上完美运行：

Jenkins 无法解析 pom 并产生以下错误：
Parsing POMs
ERROR: Failed to parse POMs
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM: Failure to transfer my.package:project:pom:${project.version} from http://mynexus.com/content/groups/default was cached in the local repository, resolution will not be reattempted until the update interval of nexus-default has elapsed or updates are forced. Original error: Could not transfer artifact my.package:project:pom:${project.version} from/to nexus-default (http://mynexus.com/content/groups/default): Illegal character in path at index 78: http://mynexus.com/content/groups/default/my/package/project/${project.version}/panda-${project.version}.pom and 'parent.relativePath' points at wrong local POM @ line 26, column 10
为了让 Jenkins 也可以解析 pom 文件，必须进行哪些更改？
链接的问题指出，maven 将无法解析孩子的属性，因为它们不存在。上面的 maven 日志表明情况并非如此。
