[rules-users] Using Advanced Enumeration Concepts in guvnor

[Stephen Masters]

The Maven Shade plugin is relatively simple to use. Below is the XML in my pom.xml. Basically, it finds all of the jars which are required by your project and bundles all of the classes (and other resources) from them into a single big fat jar. This means that keeping track of what you have added to the Guvnor class path is much simpler.

You then put the shaded jar in the WEB-INF/lib folder inside the exploded Guvnor WAR and restart Guvnor.

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>1.4</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>

                </transformer>
                <transformer
                  implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

                </transformer>
              </transformers>
              <filters>
                <filter>
                  <artifact>*:*</artifact>
                  <excludes>
                    <exclude>META-INF/*.SF</exclude>
                    <exclude>META-INF/*.DSA</exclude>
                    <exclude>META-INF/*.RSA</exclude>
                  </excludes>
                </filter>
              </filters>
            </configuration>
          </execution>
        </executions>
      </plugin>
