A startable JAR file (java(w) -jar my.jar; doubleclick on the jar) needs two
information:
- which class to start
- additional classpath entries
These information are made in the META-INF/manifest.mf in
- Main-Class: package.Driver_1
- Class-Path: path/one.jar path/two.jar
Ant's <jar> with nested <manifest> can build that jar.
Relative paths specified in Class-Path manifest entry are relative to the jar
file itself.
This means for the example above that you have a directory layout like this:
some
\- place
|my.jar
\-- path
one.jar
two.jar
For creating the needed Class-Path have a look at the <manifestclasspath> task.
The creation of the required directory layout just use <mkdir> and <copy>.
