Question about ant and packaging in jar?

Question

Apache Ant

There is the following structure:
- src
|-java
|-wsdl -target
|
-classes
-build.xml
you need to pack the contents of classes into the jar, and put the wsdl folder in the jar's META-INF (namely, with the contents, and not just the contents)

Answer 1

Yes, nothing fancy.

<jar destfile="project.jar" basedir="target/classes">
  <metainf dir="target" includes="resources/**" />
</jar>
