What does "junit47 provider with JUnit4.8+ only" and "For JUnit, this parameter forces the use of the junit47 provider" mean?

[jonahgraham]

The help refers to some items such as groups and excludedGroups as junit47 provider with JUnit4.8+ only and For JUnit, this parameter forces the use of the junit47 provider

Is this out of date, or what does it mean? Does it have a negative effect when running JUnit5 tests?

In help:

https://tycho.eclipseprojects.io/doc/latest/tycho-surefire-plugin/plugin-test-mojo.html#excludedGroups

In code:

tycho/tycho-surefire/tycho-surefire-plugin/src/main/java/org/eclipse/tycho/surefire/AbstractEclipseTestMojo.java

Lines 165 to 167 in 100be38

	* (junit47 provider with JUnit4.8+ only) Excluded groups/categories (comma-separated). Any
	* methods/classes/etc with one of the groups/categories specified in this list will
	* specifically not be run. For JUnit, this parameter forces the use of the junit47 provider

@jonahgraham yes this is likely outdated documentation as per release notes we have removed any older junit4.7 support https://github.com/eclipse-tycho/tycho/blob/tycho-5.0.x/RELEASE_NOTES.md#support-for-junit-prior-47-removed

I'll adjust the documentation, in general you should consider not using JUnit 4 provider anyways and use JUnit 5 with vintage option and if you are already using JUnit 5 then you should be able to use Junit usual filtering options instead.

Perfect, thanks for confirmation. I am using JUnit5, but I want to use excludedGroups and wanted to make sure that wasn't forcing older version of JUnit.

use Junit usual filtering options instead

I'm not sure exactly what this refers to, I plan on using excludedGroups as IIUC that is to exclude groups of @Taged tests.

I fear you need to try out what works and what not, Tycho surefire is quite outdated.
If you are open to new opportunities, you might want to try out:

https://tycho.eclipseprojects.io/doc/main/tycho-test-plugin/junit-platform-mojo.html

then you have all at hand what JUnit 5 offers...

Thanks @laeubi - I'll see what works.
