我有以下POM结构：

./foobar-common/pom.xml ./abc-window/pom.xml ./abc-datasource/pom.xml

两者 abc-window pom.xml 如下：

foob​​ar-common pom.xml 如下：

<project>
    <modelVersion>4.0.0</modelVersion>
    <name>Maven Default Project</name>
    <groupId>hu.foobar.ringcore</groupId>
    <artifactId>foobar-common</artifactId>
    <version>1.0</version>
    <packaging>pom</packaging>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <junit.version>4.10</junit.version>
        <spring.version>3.1.2.RELEASE</spring.version>
        <spring-security.version>2.0.6.RELEASE</spring-security.version>
        <commons-logging.version>1.1.1</commons-logging.version>
        <dom4j.version>1.6.1</dom4j.version>
        <javaee-api.version>6.0</javaee-api.version>
        <mycila-event.version>3.0</mycila-event.version>
        <ringcore-services.version>1.3.4-SNAPSHOT</ringcore-services.version>
        <commons-lang3.version>3.1</commons-lang3.version>
    </properties>

</project>

我的问题是，如果我按预期从父 pom 属性中提取依赖项版本mvn install。abc-datasource但是，如果我mvn install从abc-window该引用中执行，abc-datasource则版本未解决，我得到：

[ERROR] Failed to execute goal on project abc-window: Could not resolve dependencies for project hu.abc.ringcore:abc-window:jar:1.0-SNAPSHOT: Failed to collect dependencies for [junit:junit:jar:4.10 (test), hu.abc.ringcore:abc-datasource:jar:1.0-SNAPSHOT (compile)]: Failed to read artifact descriptor for org.apache.commons:commons-lang3:jar:${commons-lang3.version}: Could not transfer artifact org.apache.commons:commons-lang3:pom:${commons-lang3.version} from/to central (http://repo.maven.apache.org/maven2): IllegalArgumentException: Illegal character in path at index 70: http://repo.maven.apache.org/maven2/org/apache/commons/commons-lang3/${commons-lang3.version}/commons-lang3-${commons-lang3.version}.pom

两个项目都有相同的父 pom，所以为什么它不起作用..？

dependencyManagment在父 pom 中 使用

<dependencyManagement>
  <dependencies>
    <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <version>${junit.version}</version>
    </dependency>
    <dependency>
       <groupId>org.apache.commons</groupId>
       <artifactId>commons-lang3</artifactId>
       <version>${commons-lang3.version}</version>
    </dependency>
    </dependencies>
  </dependencyManagement>

在父 pom 中添加所有版本，并在子 pom 中使用没有版本的依赖项

编辑 

/pom.xml                 <-parent pom
/abc-window/pom.xml     <-child module  
/abc-datasource/pom.xml <-child module

并且父 pom 应该包含 

<project  
...  
   <properties>   
    ... 
   </properties>  
   <modules>  
      <module>abc-datasource</module>
      <module>abc-window</module>  
   </modules>   
   <build>
      <pluginManagment>   
       ...
      </pluginManagment>
   </build>
   <dependencyManagment>
    ...  
   </dependencyManagment>  
</project>

abc-window 中的父级列为：

    <parent>
            <relativePath>../foobar-common/pom.xml</relativePath>
            <groupId>hu.abc.ringcore</groupId>
            <artifactId>foobar-common</artifactId>
            <version>1.0</version>
        </parent>

abc-datasource 中的父级列为：

<parent>
    <relativePath>../foobar-common/pom.xml</relativePath>
    <groupId>hu.ratesoft.ringcore</groupId>
    <artifactId>foobar-common</artifactId>
    <version>1.0</version>
</parent>

因此，它们没有相同的 groupId。
