jira-importer opened a new issue, #181: URL: https://github.com/apache/maven-war-plugin/issues/181
**[Hockchai Lim](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=hockchailim)** opened **[MWAR-351](https://issues.apache.org/jira/browse/MWAR-351?redirect=false)** and commented I've a maven web module that has several dependencies that are declared with \<optional>true\</optional> in pom.xml. For example: \<dependency> \<groupId>log4j\</groupId> \<artifactId>log4j\</artifactId> \<optional>true\</optional> \</dependency> When performing packaging of this project, Maven WAR Plugin is not including those optional dependencies to the WEB-INF/lib folder, which I think is incorrect. According to https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html, optional dependency should work like transitive dependency for this web module. Optional dependency should only be ignored on projects/modules that reference this web modle. Below is the relevant sections from https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html link: How do optional dependencies work? Project-A -> Project-B The diagram above says that Project-A depends on Project-B. When A declares B as an optional dependency in its POM, this relationship remains unchanged. Its just like a normal build where Project-B will be added in its classpath. Project-X -> Project-A But when another project(Project-X) declares Project-A as a dependency in its POM, the optional dependency takes effect. You'll notice that Project-B is not included in the classpath of Project-X; you will need to declare it directly in your POM in order for B to be included in X's classpath. --- **Affects:** 2.2 1 votes, 5 watchers -- This is an automated message from the Apache Git Service.
