    <p>The problem here is that the <strong>lib</strong> tag is a custom <strong>fileset</strong> that targets it's files into the war archive's <em>lib</em> sub directory. It might be possible to write a custom <strong>war</strong> task but I don't think it's worth the effort.</p> <p>If want to improve the manner in which ivy manages your war's dependencies might I suggest using configurations?</p> <p>Create a configuration describing the run-time dependencies:</p> <pre><code> &lt;ivy-module version="2.0"&gt; &lt;info organisation="apache" module="hello-ivy"/&gt; &lt;configurations&gt; &lt;conf name="build" description="Libraries needed to for compilation"/&gt; &lt;conf name="war" extends="build" description="Libraries that should be included in the war file" /&gt; &lt;/configurations&gt; &lt;dependencies&gt; &lt;dependency org="commons-lang" name="commons-lang" rev="2.0" conf="build-&gt;*,!sources,!javadoc"/&gt; &lt;dependency org="commons-cli" name="commons-cli" rev="1.0" conf="build-&gt;*,!sources,!javadoc"/&gt; &lt;/dependencies&gt; &lt;/ivy-module&gt; </code></pre> <p>Afterwards you retrieve them into a dedicated directory (using a pattern) which can be simply included using the <strong>war</strong> task's <strong>lib</strong> tag:</p> <pre><code> &lt;ivy:retrieve pattern="${lib.dir}/[conf]/[artifact].[ext]"/&gt; &lt;war destfile="${war.file}" webxml="${resources.dir}/web.xml"&gt; &lt;fileset dir="${resources.dir}" excludes="web.xml"/&gt; &lt;lib dir="${lib.dir}/war"/&gt; &lt;/war&gt; </code></pre> <p>The advantage of this approach is that you use the ivy <strong>conf</strong> attribute of each project dependency to ultimately decide if the jar gets included within the war file or not. The build file no longer cares.</p> <p>In conclusion I understand that the point of your post was concern for multiple copies of your jar files... Using my suggested approach will further multiple your copies, but I would submit that this is not an issue provided you have a <em>clean</em> target to remove them afterwards.</p>

    1. COI agree that this is a better solution then what I am doing but it still does not remove the extra file copy as I would like. The more I look at this the more I think that, as you said, the only real way to fix is by creating a custom war task or even a new custom lib task for the war task. In a perfect world this new task could would day become part of Ivy or Ant.

    2. COThe solution you want is to use the ivy cachefileset task instead of cachepath. Then the refid parameter to the warfile's lib tag will work as expected

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
