[tycho-user] JUnit failure (Tycho 1.5 to 1.7)

[Simon Goodall <simon@xxxxxxxxxxxxxxxxxx>]

I am trying to upgrade to Tycho 1.7.0 from 1.5. However I am stuck on
running my unit tests and I am unsure where to go from here as they
appear to be tycho/maven related. The two messages that appear to be
relevant are;

Could not resolve module: org.eclipse.tycho.surefire.junit55 [196]
org.apache.maven.surefire.util.SurefireReflectionException:
java.lang.ClassNotFoundException:
org.apache.maven.surefire.junitplatform.JUnitPlatformProvider

(full stack traces below)

My application is based on Eclipse 2019-12 with the related Orbit repo
(R20191126223242) and I am running OpenJDK 11 with the majority of
tests being JUnit 5 based with a few junit4 swtbot cases. Any
suggestions appreciated otherwise I will try to reproduce a minimal
example.

Thanks

Simon
