我有2个独立的项目--第一个项目被添加到第二个项目中作为依赖关系，我不能把它们变成一个独立的项目。模块 因为使用第一个项目的maven项目数量不固定。
第一个项目的几行字
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.test</groupId>
<artifactId>first</artifactId>
<version>${artifact.version}</version>
<packaging>jar</packaging>
<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<artifact.version>2.0</artifact.version>
</properties>
第二项目绒球的几行字--
<project
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<groupId>com.test</groupId>
<modelVersion>4.0.0</modelVersion>
<artifactId>second</artifactId>
<version>1.0</version>
<packaging>bundle</packaging>
<name>second</name>
<description>second</description>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.test</groupId>
<artifactId>first</artifactId>
<version>${artifact.version}</version>
</dependency>
</dependencies>
当我们使用属性 artifact.version 从第一个项目到第二个项目，我们得到以下的错误，请让我们知道如何处理。对症下药 在其他maven项目中使用一个maven项目的属性。
com.test:first:jar的'dependencies.dependency.version'必须是一个有效的版本，但是是'${artifact.version}'。第93行，第13列

不，你不能使用依赖项的属性。
如果你需要共同的属性，你可以在不同项目使用的父POM中定义它们（这不要求它们是模块）。
