/**
 * Checks given file contents (assuming that it's build.gradle config) and finds target plugin's definition (given the plugin
 * name in a form <code>'group-id:artifact-id:'</code>. Supplies given callback with the plugin definition string (unquoted) and
 * a {@link GroovyLexer} which state points to the plugin definition string (quoted).
 * <p/>
 * Example:
 * <pre>
 *     buildscript {
 *       repositories {
 *         mavenCentral()
 *       }
 *       dependencies {
 *         classpath 'com.google.appengine:gradle-appengine-plugin:1.9.4'
 *       }
 *     }
 * </pre>
 * Suppose that this method is called for the given build script content and
 * <code>'com.google.appengine:gradle-appengine-plugin:'</code> as a plugin name argument. Given callback is supplied by a
 * string <code>'com.google.appengine:gradle-appengine-plugin:1.9.4'</code> (without quotes) and a {@link GroovyLexer} which
 * {@link GroovyLexer#getTokenStart() points} to the string <code>'com.google.appengine:gradle-appengine-plugin:1.9.4'</code>
 * (with quotes), i.e. we can get exact text range for the target string in case we need to do something like replacing plugin's
 * version.
 *
 * @param fileContents  target gradle config text
 * @param pluginName    target plugin's name in a form <code>'group-id:artifact-id:'</code>
 * @param consumer      a callback to be notified for the target plugin's definition string
 * @param <T>           given callback's return type
 * @return              given callback's call result if target plugin definition is found; <code>null</code> otherwise
