+      <p>
+        Version 1.8 of the test plugin removed a prereq on <code>java:compile</code>
+        &amp; <code>java:jar-resources</code> from the <code>test:test</code>
goal
+        for optimization reasons (see <a href="http://jira.codehaus.org/browse/MPTEST-46">MPTEST-46</a>).
+        This introduced a backward compatibility issue
+        (see <a href="http://jira.codehaus.org/browse/MPTEST-66">MPTEST-66</a>)
+        which might affect you if the following conditions are met:
+      </p>
+      <ul>
+        <li>
+          You either use <code>maven.test.skip=true</code> or your project has
no unit tests.
+        </li>
+        <li>
+          Either your project, or a plugin that you use, relies on java sources to be compiled
+          by calling the <code>test:test</code> goal.
+        </li>
+      </ul>
+      <p>
+        An illustration of the problem is provided by the
+        <a href="http://maven-plugins.sourceforge.net/maven-javaapp-plugin/index.html">javaapp</a>
+        sourceforge plugin, whose <code>javaapp:jar</code> goal has a prereq
on <code>test:test</code>,
+        relying on the java sources to be compiled by this call. If you are calling this
goal now with
+        a project that has no tests, the build will fail.
+      </p>
+      <p>
+        The problem should really be fixed in the corresponding plugin,
+        but a simple workaround is to add the missing goals as a preGoal
+        in your maven.xml:
+      </p>
+      <source><![CDATA[<preGoal name="javaapp:jar">
+  <j:if test="${unitTestSourcesPresent != 'true' or context.getVariable('maven.test.skip')
== 'true'}">
+    <attainGoal name="java:compile"/>
+    <attainGoal name="java:jar-resources"/>
+  </j:if>
+</preGoal>]]></source>
+      <p>
+        If you don't know the goal that is causing the trouble, you may add
+        the preGoal to <code>test:test</code>, but this might lead
+        to double compilation.
+      </p>
