Question

I have a standard project layout for a java project:

project /     src /         source_file_1.java         ...         source_file_N.java     build /           classes /               source_file_X.class               ...           jar /               MyJar.jar     lib /           SomeLibrary.jar           SomeOtherLibrary.jar 

As far as I can tell, I am building the project correctly with Ant. I need to set the class-path attribute in the Manifest file so my classes can use the required libraries.

The following relevant information from build.xml

<target name='compile' depends='init'>     <javac srcdir='src' destdir='build\classes'>         <classpath id='classpath'>             <fileset dir='lib'>                 <include name='**/*.jar' />             </fileset>         </classpath>     </javac> </target>  <target name='jar' depends='compile'>     <jar destfile='build\jar\MyJar.jar' basedir='build\classes' >         <manifest>             <attribute name='Built-By' value='${user.name}' />         </manifest>     </jar> </target> 

Any push in the right direction is appreciated. Thanks

Looking at my NetBeans-generated build file, I found this snippet in the -do-jar-with-libraries task:

<manifest>     <attribute name='Main-Class' value='${main.class}'/>     <attribute name='Class-Path' value='${jar.classpath}'/> </manifest> 

So in other words, it looks like you just need to add another attribute to the manifest task that you already have.

See also the Manifest Task documentation.
