Question

I have file.txt in some jar. Ant is executed with this jar on classpath. This

<available resource="file.txt" property="file.txt.exists"/>

sets the property.

How can I copy that resource to some location?

Answer 1

Assuming for you have two files in a directory:

• build.xml
• test.jar

---

build.xml

<project name="copy-file-from-jar-on-ant-classpath" default="run" basedir=".">
    <target name="run">
        <copy tofile="extracted.file.txt">
            <javaresource name="file.txt"/>
        </copy>
    </target>
</project>

test.jar contains a single file: file.txt

---

Running the following command…

ant -lib test.jar

…will extract file.txt from test.jar into the directory.
