copied!<p>How do I make the manifest available during a Maven/Surefire unittest run "mvn test" ?</p> <p>I have an open-source project that I am converting from Ant to Maven, including its unit tests. Here's the project source repository with the Maven project: <a href="http://github.com/znerd/logdoc" rel="noreferrer">http://github.com/znerd/logdoc</a></p> <p>My question pertains to the primary module, called "base". This module has a unit test that tests the behaviour of the static method <code>getVersion()</code> in the class <code>org.znerd.logdoc.Library</code>. This method returns:</p> <pre><code>Library.class.getPackage().getImplementationVersion() </code></pre> <p>The <code>getImplementationVersion()</code> method returns a value of a setting in the manifest file. So far, so good. I have tested this in the past and it works well, as long as the manifest is indeed available on the classpath at the path <code>META-INF/MANIFEST.MF</code> (either on the file system or inside a JAR file).</p> <p>Now my challenge is that the manifest file is not available when I run the unit tests:</p> <pre><code>mvn test </code></pre> <p>Surefire runs the unit tests, but my unit test fails with a mesage indicating that <code>Library.getVersion()</code> returned <code>null</code>.</p> <p>When I want to check the JAR, I find that it has not even been generated. Maven/Surefire runs the unit tests against the classes, <em>before</em> the resources are added to the classpath.</p> <p>Further investigation shows Surefire generates its own JAR file in a temporary directory, e.g.</p> <pre><code>/private/var/folders/TR/TREvj1wIHYyAcUy-xmc3UU+++TI/-Tmp-/surefirebooter7448562488934426857.jar </code></pre> <p>And then uses this JAR to load the Library class. This JAR does not contain the resources I stuck under <code>src/main/resources</code>. So putting a <code>META-INF/MANIFEST.MF</code> file also does not work.</p> <p>So how do I tell Surefire to have my <code>META-INF/MANIFEST.MF</code> file available from the same class loader as the <code>Library</code> class.</p> <blockquote> <p>Note that I use Maven 2.2.0, Java 1.6.0_17 on Mac OS X 10.6.2, with JUnit 4.8.1.</p> </blockquote>
