Question

我是从常春藤缓存中检索一个jar到一个lib文件夹，下面是ivy.xml代码：

    <configurations>
        <conf name="specificFolder"  description="add jar to web-inf/lib folder"/>
    </configurations>
    <dependencies>
        <dependency org="javax.servlet" name="servlet-api" rev="2.4" transitive="false" conf="specificFolder"/>
        <dependency org="org.springframework" name="spring-beans" rev="2.5.5" transitive="false" />
        <dependency org="org.springframework" name="spring-webmvc" rev="2.5.5" transitive="false" />
        <dependency org="org.springframework" name="spring-web" rev="2.5.5" transitive="false" />
        <dependency org="org.springframework" name="spring-context" rev="2.5.5" transitive="false" />
        <dependency org="org.springframework" name="spring" rev="1.2.6" transitive="false" />

然后这是蚂蚁目标：

<target name="test">
    <ivy:retrieve pattern="lib/[artifact](.[ext])" sync="true" type="jar" conf="specificFolder"/>
</target>

但我得到了“未解决的依赖”，这是我做错了什么？

我重现了您的问题，这是相关的错误消息：

[ivy:resolve]       ::::::::::::::::::::::::::::::::::::::::::::::
[ivy:resolve]       ::          UNRESOLVED DEPENDENCIES         ::
[ivy:resolve]       ::::::::::::::::::::::::::::::::::::::::::::::
[ivy:resolve]       :: javax.servlet#servlet-api;2.4: configuration not found in javax.servlet#servlet-api;2.4: 'specificFolder'. It was required from com.myspotontheweb#demo;????? specificFolder
[ivy:resolve]       ::::::::::::::::::::::::::::::::::::::::::::::

根本原因是以下依赖声明：

<dependency org="javax.servlet" name="servlet-api" ... conf="specificFolder"/>

虽然模块中存在配置，但远程Maven模块中不存在该配置。有关如何查看以下答案的更多详细信息：

How are maven scopes mapped to ivy configurations by ivy

工作示例

的ivy.xml

<ivy-module version="2.0">
    <info organisation="com.myspotontheweb" module="demo"/>

    <configurations>
        <conf name="specificFolder"  description="add jar to web-inf/lib folder"/>
    </configurations>
    <dependencies>
        <dependency org="javax.servlet" name="servlet-api" rev="2.4"            conf="specificFolder->master"/>
        <dependency org="org.springframework" name="spring-beans" rev="2.5.5"   conf="specificFolder->master"/>
        <dependency org="org.springframework" name="spring-webmvc" rev="2.5.5"  conf="specificFolder->master"/>
        <dependency org="org.springframework" name="spring-web" rev="2.5.5"     conf="specificFolder->master"/>
        <dependency org="org.springframework" name="spring-context" rev="2.5.5" conf="specificFolder->master"/>
        <dependency org="org.springframework" name="spring" rev="1.2.6"         conf="specificFolder->master"/>
    </dependencies>

</ivy-module>

注意：

此示例使用配置映射而不是“transitive = false”。本地配置是“specificFolder”，远程配置是特殊的“master”。 “master”由Maven模块提供，表示没有依赖关系的远程工件。一旦了解配置如何工作，我认为这种方法更简单。（Maven中非常强大的概念）
