Tests have been silently reporting "Tests run: 0" since dsldevkit#1292 (2026-04-01) bumped orbit-aggregation from 2025-09 to 4.39.0. Tycho-Surefire treats zero discovered tests as success, so CI remained green while test coverage dropped to nothing. Root cause: orbit-aggregation 4.38.0+ ships every JUnit Jupiter, Platform, and Vintage IU at both the 5.x and 6.x version families simultaneously. Tycho's planner pulls in both families, so the OSGi runtime ends up with two Class<?> instances of JUnit Platform types, producing LinkageError / ArrayStoreException during test discovery (different classloaders for the same FQN). orbit-aggregation 4.37.0 (Sept 2025) is the last release that ships JUnit at a single family (5.13.4 / Platform 1.13.4) and matches Eclipse 4.34's PDE JUnit runtime bridge. Pinning to it, removing the now-redundant maven-osgi/release/4.39.0 location, and inlining the JUnit IUs at 5.13.4 / 1.13.4 restores the three JUnit-Platform-bearing classloaders to a single agreed version. Also dropped: the unused releases/2022-12 UML2 location, which was a stealth source of additional JUnit 5.9.1 / 1.9.1 IUs (DDK does not consume any UML2 features). Verified locally on macOS aarch64: 307 tests across 75 classes, 0 failures. Tycho-Surefire's auto-detection selects the junit5vintage provider given Jupiter + vintage-engine on the classpath; no providerHint override is needed. This is step 1 of a staged plan. Subsequent PRs will: step 2 - migrate remaining JUnit 4 source surface to Jupiter step 3 - drop org.junit 4.13.2 and junit-vintage-engine entirely step 4 - upgrade to JUnit 6 + Eclipse 4.39 atomically Credit: Kris Limbo's dsldevkit#1320 / dsldevkit#1321 (Plan A / Plan B) proved the JUnit 5 migration direction; both encountered the same LinkageError during diagnosis that this fix sidesteps via version alignment.

…IfNecessary call XtextBuildTrigger.scheduleFullBuild() invokes buildScheduler.scheduleBuildIfNecessary(projects) - single arg, no IBuildFlag varargs - but the test verified the call with two matchers: eq(projects) and ArgumentMatchers.<IBuildFlag[]>any(). Mockito 5.x treats the second matcher as expecting a second explicit argument, not "varargs may be empty", so verify reports an argument-count mismatch: Wanted: scheduleBuildIfNecessary([], <any>); Actual: scheduleBuildIfNecessary([]); The test passed under Mockito 4.x where vararg `any()` matched zero or more vararg invocations. This isn't introduced by step 1's 5.21->5.19 patch bump; both are strict. Master has had Mockito 5.x in scope since orbit-aggregation 4.39 (PR dsldevkit#1292), but tests being silent-zero (Tycho-Surefire reporting `Tests run: 0` as success) hid the failure. Step 1 restores test discovery, which surfaces this latent mismatch and makes the test fail deterministically (verified locally: 307 tests, 1 failure on this exact assertion). Drop the second matcher on both verify sites (the never() check and the positive verify); they now match the production single-arg call. The IBuildFlag import is no longer needed. Bundled in PR dsldevkit#1323 so its "restored 307 tests" claim lands green; splitting would ship the orbit-pin PR with a known-failing test.

Tycho-Surefire reports `Tests run: 0` as exit code 0, so a broken test discovery yields a green build with no tests run. PR dsldevkit#1292 went undetected for ~30 days for this reason: orbit-aggregation 4.39.0 introduced JUnit 5.x and 6.x simultaneously, breaking JUnit Platform discovery, and CI happily reported pass. Tycho-Surefire writes no TEST-*.xml when discovery yields zero, so a file-existence check on `**/target/surefire-reports/TEST-*.xml` suffices to catch the silent-zero failure mode. The step runs with `if: always()` so it fires even after build failures. Verified empirically: master (orbit-4.39.0, silent-zero) produces 0 TEST-*.xml; the check correctly fails. Working state (orbit-4.37.0, 357 tests) produces 81 TEST-*.xml; check passes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
1. Select the plugin versions in the target file. 2. Re-pin orbit aggregation back to 4.39.0. Removed reference to org.junit 4.13.2. 3. Upgrade Eclipse release to 2026-03. 4. Removed references to junit-vintage-engine. 5. Migrate remaining JUnit4 Assert Calls as per PR1325.

This is on top of your junit-silent-zero-pin-step-1, Joao.
I believe this is the minimum set of changes to make the tests run on JUnit 5.
