-----------------------------------------

             Summary: Jupiter engine transitively included in war file
                 Key: WICKET-6837
                 URL: https://issues.apache.org/jira/browse/WICKET-6837
             Project: Wicket
          Issue Type: Bug
          Components: wicket-core
    Affects Versions: 9.0.0
            Reporter: Gert-Jan Schouten


If I run mvn dependency:tree on this basic war pom:
{noformat}
<?xml version="1.0"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>test</groupId>
	<artifactId>test</artifactId>
	<packaging>war</packaging>
	<version>1.0</version>
	<dependencies>
			<dependency>
				<groupId>org.apache.wicket</groupId>
				<artifactId>wicket-core</artifactId>
				<version>9.0.0</version>
				<type>jar</type>
				<scope>compile</scope>
			</dependency>
	</dependencies>
</project>{noformat}
then the output is this:

The org.junit.jupiter:junit-jupiter-engine:jar should not have compile scope, because it means that it will be included in war files that use wicket-core.

 

I believe this is caused by the fact that wicket-util overrides the scope of org.junit.jupiter:junit-jupiter-engine:jar and sets it to "compile". As far as I understand, overriding the <scope> stops a dependency from inheriting the <optional> element, after which the <optional> element will default to "false".

This can be solved by adding the <optional> element to org.junit.jupiter:junit-jupiter-engine:jar and setting it to "true" in wicket-util.

The wicket-examples war is not affected by this. I think this is because the wicket-examples war file _itself_ inherits from wicket-parent, in which case I have no idea how it affects the scope/optional resolution :) Anyway, this is not representative of a typical war file, which would not inherit from wicket-parent.
