Custom Maven plugin for encryption

Question

I'm translating an Ant script to Maven 2 and I have this problem: the Ant script use a pretty simple java class to encrypt files this way:

<target name="encrypt">
    <java classname="DESEncrypter">
        <classpath>
            <pathelement path="...classpath for this thing..." />
        </classpath>
        <arg line="fileToEncrypt.properties fileEncrypted.properties" />
    </java>
</target>

This DESEncrypter is a compiled class which source doesn't belong to the project I am converting but is used similarly in other projects. Probably I have to create a maven plugin for this to reuse, but I don't want to do it now. My question is: in which directory do i put the DESEncrypter class and how do i invoke it? Using the exec:java plugin, may be? I don't think the encrypter belong to src, test or resources directories.

Obviously, I don't want to include the encrypter class in the final product, just the encrypted files.

A very straightforward solution would be to use the Maven AntRun Plugin. Regarding the location of your encrypter, you could either:

• put it in a separate module that you could declare as dependency OF the plugin (see this example)
• keep it in the current module, in the source tree, and configure the Maven JAR Plugin to exclude it using excludes.
