It will take a named file in the <tt>jar</tt> attribute, and an optional <tt>destDir</tt> or <tt>signedJar</tt> attribute. Nested paths are also supported; here only an (optional) <tt>destDir</tt> is allowed. If a destination directory or explicit JAR file name is not provided, JARs are signed in place. </p> <p> Dependency rules </p> <ul> <li>Nonexistent destination JARs are created/signed</li> <li>Out of date destination JARs are created/signed</li> <li>If a destination file and a source file are the same, and <tt>lazy</tt> is true, the JAR is only signed if it does not contain a signature by this alias.</li> <li>If a destination file and a source file are the same, and <tt>lazy</tt> is false, the JAR is signed.</li> </ul> <h3>Parameters</h3> <table border="1" cellpadding="2" cellspacing="0"> <tr> <td valign="top"><b>Attribute</b></td> <td valign="top"><b>Description</b></td> <td align="center" valign="top"><b>Required</b></td> </tr> <tr> <td valign="top">jar</td> <td valign="top">the jar file to sign</td> <td valign="top" align="center">Yes, unless nested paths have been used.</td> </tr> <tr> <td valign="top">alias</td> <td valign="top">the alias to sign under</td> <td valign="top" align="center">Yes.</td> </tr> <tr> <td valign="top">storepass</td> <td valign="top">password for keystore integrity.</td> <td valign="top" align="center">Yes.</td> </tr> <tr> <td valign="top">keystore</td> <td valign="top">keystore location</td> <td valign="top" align="center">No</td> </tr> <tr> <td valign="top">storetype</td> <td valign="top">keystore type</td> <td valign="top" align="center">No</td> </tr> <tr> <td valign="top">keypass</td> <td valign="top">password for private key (if different)</td> <td valign="top" align="center">No</td> </tr> <tr> <td valign="top">sigfile</td> <td valign="top">name of .SF/.DSA file</td> <td valign="top" align="center">No</td> </tr> <tr> <td valign="top">signedjar</td> <td valign="top">name of signed JAR file.

The flatten mapper means that they will all be copied to this directory, not to subdirectories. </p> <blockquote><pre> <signjar alias="testonly" keystore="testkeystore" storepass="apacheant" lazy="true" > <path> <fileset dir="dist" includes="**/*.jar" /> </path> </signjar> </pre></blockquote> <p> Sign all the JAR files in dist/**/*.jar <i>in-situ</i>. Lazy signing is used, so the files will only be signed if they are not already signed. </p> <h3>About timestamp signing</h3> <p> Timestamped JAR files are a new feature in Java1.5; a feature supported in Ant since Ant 1.7. Ant does not yet support proxy setup for this singing process, and the whole TSA feature is not tested yet. Furthermore, the <a href="http://java.sun.com/j2se/1.5.0/docs/guide/security/time-of-signing-beta1.html"> official TSA documentation</a> warns that the API is subject to change. If a future version of Java changes the API, Ant will break. It may be possible to hide changes if and when they occur, but this can not be guaranteed. </p> </body> </html>
