我希望 Ivy 获取 log4j .jar 和 JavaDocs。现在，我处于死胡同。如果我在 ivy.xml 中使用它...
<dependency org="log4j" name="log4j" rev="1.2.16"/>
...然后我只得到 .jar 文件。但是当使用这个 ivysettings.xml ...
<?xml version="1.0" encoding="UTF-8"?>
<ivysettings>
<settings
defaultResolver="default"
defaultConflictManager="all" />
<resolvers>
<url name="default" m2compatible="true">
<artifact pattern="http://repo1.maven.org/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/>
<artifact pattern="http://repo2.maven.org/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/>
</url>
</resolvers>
</ivysettings>
... 而这个 ivy.xml ...
<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
<info organisation="foo" module="bar"/>
<dependencies>
<dependency org="log4j" name="log4j" rev="1.2.16">
<artifact name="log4j" type="jar" ext="jar"/>
<artifact name="log4j" type="javadoc" ext="jar"/>
</dependency>
</dependencies>
</ivy-module>
...然后我收到此错误消息： java.lang.RuntimeException: 模块 log4j#log4j;1.2.16 的多个工件被检索到同一个文件！更新检索模式以修复此错误。
我在这里缺少什么？如何让 Ivy 解析 JavaDoc 和 .jar 文件？
编辑：感谢迄今为止所有快速而详细的回复。这是我更新的 ivy.xml：
<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation=
"http://ant.apache.org/ivy/schemas/ivy.xsd">
<info organisation="foo" module="bar"/>
<configurations>
<conf name="default" visibility="public"/>
<conf name="compile" visibility="public"/>
<conf name="master" visibility="public"/>
<conf name="javadoc" visibility="public"/>
</configurations>
<dependencies>
<dependency org="log4j" name="log4j" rev="1.2.16" conf="default->master,javadoc"/>
<dependency org="javax.servlet" name="servlet-api" rev="2.5" />
<dependency org="com.someother" name="proprietary-core" rev="1.2.3" force="true"/>
<dependency org="com.someother" name="proprietary" rev="1.2.3" force="true"/>
<dependency org="com.someother" name="scanner" rev="1.0" force="true"/>
</dependencies>
</ivy-module>
现在我收到此错误消息：

Maven 范围似乎有问题。但我到底错过了什么？
