    <p>I'm converting a build that has 71 <code>.jar</code> files in its global <code>lib/</code> directory to use Maven. Of course, these have been pulled from the web by lots of developers over the past ten years of this project's history, and weren't always added to VCS with all the necessary version info, etc.</p> <p>Is there an easy, automated way to go from that set of <code>.jar</code> files to the corresponding <code>&lt;dependency/&gt;</code> elements for use in my <code>pom.xml</code> files? I'm hoping for a web page where I can submit the checksum of a jar file and get back an XML snippet. The google hits for 'maven repository search' are basically just finding name-based searches. And <a href="http://repo1.maven.org/" rel="noreferrer">http://repo1.maven.org/</a> has no search whatsoever, as far as I can see.</p> <p>Update: <a href="http://grepcode.com/" rel="noreferrer">GrepCode</a> looks like it can find projects given an MD5 checksum. But it doesn't provide the particular details (<code>groupId</code>, <code>artifactId</code>) that Maven needs.</p> <p>Here's the script I came up with based on the accepted answer:</p> <pre><code>#!/bin/bash for f in *.jar; do s=`md5sum $f | cut -d ' ' -f 1`; p=`wget -q -O - "http://www.jarvana.com/jarvana/search?search_type=content&amp;content=${s}&amp;filterContent=digest" | grep inspect-pom | cut -d \" -f 4`; pj="http://www.jarvana.com${p}"; rm -f tmp; wget -q -O tmp "$pj"; g=`grep groupId tmp | head -n 1 | cut -d \&gt; -f 3 | cut -d \&lt; -f 1`; a=`grep artifactId tmp | head -n 1 | cut -d \&gt; -f 3 | cut -d \&lt; -f 1`; v=`grep version tmp | head -n 1 | cut -d \&gt; -f 3 | cut -d \&lt; -f 1`; rm -f tmp; echo '&lt;dependency&gt; &lt;!--' $f $s $pj '--&gt;'; echo " &lt;groupId&gt;$g&lt;/groupId&gt;"; echo " &lt;artifactId&gt;$a&lt;/artifactId&gt;"; echo " &lt;version&gt;$v&lt;/version&gt;"; echo "&lt;/dependency&gt;"; echo; done </code></pre>

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.
