c -> c.getAttributes().attribute(javaModule, true));

        // all Jars have a javaModule=false attribute by default; the transform also recognizes modules and returns them without modification
        project.getDependencies().getArtifactTypes().getByName("jar").getAttributes().attribute(javaModule, false);

        // register the transform for Jars and "javaModule=false -> javaModule=true"; the plugin extension object fills the input parameter

following discovery algorithm to select the name of the LogFactory implementation class this application wants to use: Check for a system property named org.apache.commons.logging.LogFactory. Use the JDK 1.3 JAR Services Discovery mechanism (see http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html for more information) to look for a resource named META-INF/services/org.apache.commons.logging.LogFactory whose first line is assumed to contain the desired class name. Look for a properties file named...

For example, if the configuration consists of the artifacts `lib1.jar`, `lib2.jar`, `lib3.jar`, and the transform action registers a minified output artifact `<artifact-name>-min.jar` for the input artifact, then the transformed configuration consists of the artifacts `lib1-min.jar`, `lib2-min.jar` and `lib3-min.jar`.

Here is the implementation of an `Unzip` transform which transforms a JAR file into a classes directory by unzipping it.

`destinationDirectory`::
Defaults to `distsDirectory` for non-JAR archives and `libsDirectory` for JARs and derivatives of JAR, such as WARs.

`archiveVersion`::
Defaults to `$project.version` or 'unspecified' if the project has no version.

`archiveBaseName`::
Defaults to `$archivesBaseName`.
