[tycho-user] Problem with dependency resolution when running tests with

[Hallvard Trætteberg <hal@xxxxxxx>]

Hi,

I'm using Tycho to build plantuml (plugins, features and repository), and suddenly have started getting dependency resolution errors when running UI tests. I discovered it when upgrading to Tycho 1.5, and I'm pretty sure it worked with 1.3. However, when rolling back, I get the same errors. The build is pomless, with the Tycho version indicated in the .mvn/extensions.xml file. The target refers to Luna, i.e. a pretty old target, but it did work pretty recently. I tried upgrading to maven 3.6.2 (from 3.3), but needed to downgrade to 3.6.0. Here's the output of mvn --version:

Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)
Maven home: /usr/local/Cellar/maven@3.5/3.5.4/libexec
Java version: 1.8.0_222, vendor: Eclipse OpenJ9, runtime: /Users/hal/.sdkman/candidates/java/8.0.222.j9-adpt/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.5", arch: "x86_64", family: "mac"

The build consists of several ordinary plugins and test plugins. Compiling works, it's when running the (UI) tests with tycho-surefire, which is supposed to launch Eclipse, I get the dependency resolution error:

[ERROR] Cannot resolve project dependencies:
[ERROR]   Software being installed: net.sourceforge.plantuml.eclipse.tests 1.1.24.qualifier
[ERROR]   Missing requirement: net.sourceforge.plantuml.eclipse.tests 1.1.24.qualifier requires 'osgi.bundle; net.sourceforge.plantuml.eclipse.imagecontrol 1.1.24.qualifier' but it could not be found

The strange thing is that the missing dependency is to one of the plugins (net.sourceforge.plantuml.eclipse.imagecontrol) in the same build that resolved correctly during compilation. The build output for that plugin seems ok. There are no other dependency errors, I'm not sure how or if it would be reported if net.sourceforge.plantuml.eclipse.imagecontrol missed some dependencies. That imagecontrol plugin mainly depends on swt and jface, but as mentioned there are no messages about missing (transitive) dependencies. BTW, I have a dependency in the pom to the eclipse-feature org.eclipse.e4.rcp, but there is no reference to it in the build output.

I've read the release notes for 1.4 and 1.5, and didn't see anything that should break the existing setup. I'm clueless to what to do, any suggestions?

Regards,

Hallvard
