我有一个maven项目,使用一些自定义jar [在任何存储库中找不到].要将它们与Maven构建一起添加,我在maven中使用attach-artifact目标.以下是我的pom文件：
<?xml version="1.0" encoding="UTF-8"?>
<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">

<type>jar</type>
</artifact>
</artifacts>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
我使用这些jar [customjar1.jar,customjar2.jar]的项目依赖于上述的pom文件[adminbuild].
当我执行mvn clean install命令时,我得到以下错误：
[ERROR] Failed to execute goal org.codehaus.mojo:build-helper-maven-plugin:1.7:attach-artifact (attach-artifacts) on project adminbuild: The artifact with same type and classifier: jar:null is used more than once. -> [Help 1]
以下是mvn -version命令的输出：
Apache Maven 3.0.3 (r1075438; 2011-02-28 23:01:09+0530) Maven home: C:\maven Java version: 1.6.0_26,vendor: Sun Microsystems Inc. Java home: C:\Java\jdk1.6.0_26\jre Default locale: en_IN,platform encoding: Cp1252 OS name: "windows 7",version: "6.1",arch: "amd64",family: "windows"
似乎我附加的文物的方式是不正确的.我不应该在同一个pom文件中附加多个工件？如果是,那么如何.请帮忙.
