| |
| <div class="id_context"><p class="anchor_topictop">A cyclical dependency between two |
| or more modules in an enterprise application most commonly occurs when projects |
| are imported from outside the workbench. When a cycle exists between two or |
| more modules in an enterprise application, the Java™ builder cannot accurately compute the |
| build order of the projects. Full builds fail under these conditions, or require |
| several invocations.</p> |
| <p>Therefore, the best practice is to organize your |
| projects or modules into components. This allows your module dependencies |
| to function as a tree instead of a cycle diagram. This practice has the added |
| benefit of producing a better factored and layered application.</p> |

| <li><span>Identify all the classes within the JAR files that have cyclical |
| dependencies, then move those classes into a common Java project |
| or JAR file.</span></li> |
| |
| <li><span>Use the enterprise application editor to map utility JAR files |
| to the common projects.</span></li> |
| |
| <li><span>Use the JAR dependency editor or properties page, for each module |
| of the JAR in the application, to set dependencies only to the JAR files that |
| are truly required.</span></li> |
