Re: [tycho-user] Tycho and Project Classpath
Hello,

if your dependency is copied during build process to the final location, the problem could be that tycho resolves these classpath entries only during initial computation of the target platform dependencies.
So, if your jar is not checked out , it is not present physically but only be added as external dependency if nestedJarOrDir.isFile() is true in org.eclipse.tycho.core.maven.MavenDependencyInjector.newExternalDependencies(ArtifactDescriptor).

So, to test this, just copy the dependency jar to the final location before maven starts and see if it works then.

We had a similar problem with scala-compiler not picking up any nested jars which will be created during maven build runtime and therefore had to prefix maven builds with ANT/Groovy step to create 0 byte nested jars.

Hope this helps
Henrik

Hi,

i have a question on how tycho provides the project classpath.
we have a user of our xtend maven plugin 
calls it inside a tycho project.

- he has a lib folder with a jar in build.properties / Manifest
- the jar is not checked in but copied with the maven dependencies plugin
- the jar is visible to the tycho compiler plugin
- the jar is not visible inside project.getCompileClasspathElements

is that intended? how can this be circomvented?

Thanks
