How to build jar using ant without META-INF folder? I have not specified any manifest attribute in:

```
<jar destfile="${build}/${jar}/${client}.jar" basedir="${build}/${classes}/${main}">
    <fileset file="${src}/${main}/application-context.xml" />
    <fileset file="${src}/${main}/log4j.xml" />
</jar>

```

But the jar file containing META-INF folder. Is there any way to exclude this folder's creation?

Edit:

The complete build.xml is:

```
<?xml version="1.0" encoding="UTF-8"?>
