How do I solve Multiple artifacts of the module X are retrieved to the same file in Apache Ivy?
提问by Jaanus
I was using ANT to deploy my stuff to Tomcat. But I had trouble with missing dependencies and I wanted to add Ivy, cause it was reccomended.
我正在使用 ANT 将我的东西部署到 Tomcat。但是我在缺少依赖项时遇到了麻烦，我想添加 Ivy，因为它是推荐的。
Now I added this to my build.xml file:
现在我将它添加到我的 build.xml 文件中：
<!-- Ivy settings start-->
<condition property="ivy.home" value="${env.IVY_HOME}">
<isset property="env.IVY_HOME" />
</condition>
<target name="download-ivy" unless="offline" description="Download Ivy">
<mkdir dir="${ivy.jar.dir}"/>
<!-- download Ivy from web site so that it can be used even without any special installation -->
<get src="http://repo2.maven.org/maven2/org/apache/ivy/ivy/${ivy.install.version}/ivy-${ivy.install.version}.jar"
dest="${ivy.jar.file}" usetimestamp="true"/>
</target>
<target name="init-ivy" depends="download-ivy" description="Initialize Ivy">
<!-- try to load ivy here from ivy home, in case the user has not already dropped
it into ant's lib dir (note that the latter copy will always take precedence).
We will not fail as long as local lib dir exists (it may be empty) and
ivy is in at least one of ant's lib dir or the local lib dir. -->
<path id="ivy.lib.path">
<fileset dir="${ivy.jar.dir}" includes="*.jar"/>
</path>
<taskdef resource="org/apache/ivy/ant/antlib.xml"
uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/>
</target>
<target name="update" depends="init-ivy" description="Download project dependencies">
<!-- edited for brevity -->
<ivy:retrieve pattern="lib/[conf]/[artifact]-[revision].[ext]" />
<!-- edited for brevity -->
</target>
<target name="clean-all" depends="clean" description="Purge ivy cache">
<ivy:cleancache/>
</target>
<!-- Ivy settings end-->
This is my ivy.xml:
这是我的 ivy.xml：
<ivy-module version="2.0">
<info organisation="org.apache" module="hello-ivy"/>
<dependencies>
<dependency org="commons-lang" name="commons-lang" rev="2.1"/>
</dependencies>
</ivy-module>
This is my log:

This is the error:
这是错误：
BUILD FAILED
C:\Users\Jansu\workspace\HelloWorld\build.xml:177: impossible to ivy retrieve: java.lang.RuntimeException: problem during retrieve of org.apache#hello-ivy: java.lang.RuntimeException: Multiple artifacts of the module commons-lang#commons-lang;2.1 are retrieved to the same file! Update the retrieve pattern to fix this error.
Total time: 11 seconds
It seems that error comes from this pattern? :
似乎错误来自这种模式？：
<ivy:retrieve pattern="lib/[conf]/[artifact]-[revision].[ext]" />
But it looks solid to me.
但对我来说它看起来很坚固。
Any suggestions?
有什么建议？
回答by oers
You have to expand your pattern to include the type, so that each artifact gets it's own local file:
您必须扩展您的模式以包含类型，以便每个工件都有自己的本地文件：
<ivy:retrieve pattern="lib/[conf]/[artifact]-[type]-[revision].[ext]" />
Or if you don't need the sources and the javadoc you can change the dependency to:
或者，如果您不需要源代码和 javadoc，您可以将依赖项更改为：
<ivy-module version="2.0">
<info organisation="org.apache" module="hello-ivy"/>
<dependencies>
<dependency org="commons-lang" name="commons-lang" rev="2.1" conf="default->master"/>
</dependencies>
</ivy-module>
Which will only retrieve the master-conf(jar) of the dependency.
这只会检索依赖项的 master-conf(jar)。
