Eclipse e4 RCP maven tycho -> Cannot resolve project dependencies

[pvip]

Hi,

I have created an Eclipse e4 RCP Plugin project with a product specification and some plug-in's.

Now I have defined some pom files for the target,parent and build definition using Tycho and included all modules to my build process.
This is working well and compiles/created the final product.

Some of the defined plugins in the "main" plugin.xml file are marked as 'optional'.
These plugins are not required for the core functionality. They contribute some menu items and implement the handlers itself.
Also I have removed them from the product file!

If I want to exclude some modules (which are marked as optional) tycho throws an excption that 'Cannot resolve project dependencies'.
The missing modules/plugins aren't needed for the compilation and the only reference is the 'optional' marked listing in the plugin.xml

I do not know what I am doing wrong

Any ideas?

Thanks

Its not like anyone here can look at your setup, configuration files and the steps you take to do this. I don't know what kind of help you expect people to be able to give you.

Start by actually explaining HOW you exclude the optional modules. What do you do?

Yes your right but it is difficult to hide all company specific parts.

Here is my root pom file

This is working

Now if I remove some optional dependencies

<?xml version="1.0" encoding="UTF-8"?>
<project
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

	<packaging>pom</packaging>
	<name>PARENT</name>

	<properties>
		<tycho.version>0.22.0</tycho.version>

	</properties>

	<modules>
		<module>application/xx.yy.e4.zz.core/platform/pom.xml</module>
		<module>application/xx.yy.e4.zz.core/pom.xml</module>
		<module>application/xx.yy.e4.zz.entity/pom.xml</module>
		<module>application/pom.xml</module>
	</modules>
	
	<build>
	
		<plugins>

			<plugin>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>tycho-maven-plugin</artifactId>
				<version>${tycho.version}</version>
				<extensions>true</extensions>
			</plugin>

			<plugin>

				<groupId>org.eclipse.tycho</groupId>
				<artifactId>target-platform-configuration</artifactId>
				<version>${tycho.version}</version>

				<configuration>
				
					<target> 
						<artifact> 
							<groupId>xx.yy.e4</groupId> 
							<artifactId>xx.yy.e4.zz.target</artifactId> 
							<version>0.0.1-SNAPSHOT</version>
							<classifier>zz</classifier> 
						</artifact> 
					</target>
					
					<environments>
						<environment>
						  <os>win32</os>
						  <ws>win32</ws>
						  <arch>x86_64</arch>
						</environment>
					</environments>
					
				</configuration>

			</plugin>

		</plugins>
		
	</build>

</project>

The build fails with the exception "Cannot resolve project dependencies 'xx.yy.e4.zz.log'" and this plugin is marked as optional, also it is not included in the current .product file.

It may be optional to the dependency, apparently it is not optional according to whatever pom files are in play here. Rather than remove the dependencies entirely, just put them in scope "provided" so they do not end up in the deployed artifact.
