使用Maven分类器作为依赖(Using the Maven classifier as a dependence)

 我在工作空间中有一堆项目，每个项目都有自己的pom.xml ，它使用maven-assembly-plugin生成自己的zip和一个名为foo的分类器，如下所示： 
 
<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <executions>
        <execution>
            <goals><goal>single</goal></goals>
            <phase>package</phase>
            <configuration>
                <classifier>foo</classifier>
                <descriptors>
                    <descriptor>foo.xml</descriptor>
                </descriptors>
            </configuration>
        </execution>
    </executions>
</plugin>
 
 我还有一个项目，我打算用foo分类器使用maven-dependency-plugin复制上述项目中生成的所有jar，如下所示： 
 
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.9</version>
            <executions>
                <execution>
                    <id>copy</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy</goal>
                    </goals>
                    <configuration>
                        <artifactItems>
                            <artifactItem>
                                <groupId>my.group.id</groupId>
                                <artifactId>project1</artifactId>
                                <version>${project.version}</version>
                                <classifier>foo</classifier>
                                <type>zip</type>
                                <overWrite>true</overWrite>
                            </artifactItem>
                            <!-- similar artifactItem tags for project, 2, 3, etc -->
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
<dependencies>
    <dependency>
        <groupId>my.group.id</groupId>
        <artifactId>project1</artifactId>
        <version>${project.version}</version>
        <classifier>source</classifier>
    </dependency>
</dependencies>
 
 但是我收到这些pom文件的错误说： 找不到Project1：jar：foo：{version} -SNAPSHOT { http：// repositoryURL }缓存在本地存储库中，解决方案将不会重新尝试，直到更新间隔为代理中心已经过去或强制更新。 
 
 我不明白为什么当我打算从本地版本中复制时maven正试图从存储库下载它。 其他项目确实生成了相应的归档。 我错过了什么或做错了什么？ 

I have a bunch of projects in a workspace where each project has its own pom.xml which generates its own zip with a classifier called foo using the maven-assembly-plugin as below: 
 
<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <executions>
        <execution>
            <goals><goal>single</goal></goals>
            <phase>package</phase>
            <configuration>
                <classifier>foo</classifier>
                <descriptors>
                    <descriptor>foo.xml</descriptor>
                </descriptors>
            </configuration>
        </execution>
    </executions>
</plugin>
 
I have one more project where I intend to copy all of the jars generated in the above projects with the foo classifier using the maven-dependency-plugin as below:
 
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.9</version>
            <executions>
                <execution>
                    <id>copy</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy</goal>
                    </goals>
                    <configuration>
                        <artifactItems>
                            <artifactItem>
                                <groupId>my.group.id</groupId>
                                <artifactId>project1</artifactId>
                                <version>${project.version}</version>
                                <classifier>foo</classifier>
                                <type>zip</type>
                                <overWrite>true</overWrite>
                            </artifactItem>
                            <!-- similar artifactItem tags for project, 2, 3, etc -->
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
<dependencies>
    <dependency>
        <groupId>my.group.id</groupId>
        <artifactId>project1</artifactId>
        <version>${project.version}</version>
        <classifier>source</classifier>
    </dependency>
</dependencies>
 
But I get a error with these pom files saying: Failure to find Project1:jar:foo:{version}-SNAPSHOT in {http://repositoryURL} was cached in the local repository, resolution will not be reattempted until the update interval of proxy-central has elapsed or updates are forced.
 
I don't understand why maven is trying to download it from the repository when I just intend to do a copy from local builds. The other projects do have the appropriate archives generated. What am I missing or doing wrong?
