commit 26462b1e7aa512da9612212eab5c1154f519ed52 Author: Roy Teeuwen <[email protected]> AuthorDate: Wed Jun 3 21:04:16 2026 +0200 SLING-13233: aggregate features from goal-time paths with optional OSGi BSN collision detection Add two parameters to `<aggregate>` in `slingfeature-maven-plugin:aggregate-features`: * `<additionalFeatureFiles>` — a list of feature JSON files read at goal time and merged into the selection. Unlike `<filesInclude>`, these paths bypass the session-start Preprocessor scan, so they can reference outputs produced earlier in the same build (e.g. cpconverter JSON under `target/`). * `<osgiBsnCollisionDetection>` — when `true`, the aggregator calls `BuilderContext.setOsgiBsnCollisionDetection(true)` (requires `org.apache.sling.feature` 2.0.6+) so the build fails when two bundles share the same OSGi `Bundle-SymbolicName`+`Bundle-Version` across different Maven coordinates unless an existing `<artifactsOverrides>` rule resolves them. This is an alternative aggregation flow to the launcher-plugin parameters added in https://github.com/apache/sling-feature-launcher-maven-plugin/pull/32; both produce the same on-disk aggregated feature, but the slingfeature-maven-plugin flow exposes the result to downstream goals in the same build. Bumps `org.apache.sling.feature` 2.0.0 → 2.0.6 for the new BuilderContext API. Tests: 3 new tests covering merge, missing-file, and collision-flag propagation. 20/20 existing unit tests still pass; 16/16 integration tests still pass. --- pom.xml | 2 +- .../sling/feature/maven/mojos/Aggregate.java | 27 +++++++++- .../feature/maven/mojos/AggregateFeaturesMojo.java | 37 ++++++++++++++ .../maven/mojos/AggregateFeaturesMojoTest.java | 58 ++++++++++++++++++++++ 4 files changed, 121 insertions(+), 3 deletions(-) diff --git a/pom.xml b/pom.xml index b351f6e..aa55da9 100644 --- a/pom.xml +++ b/pom.xml @@ -48,7 +48,7 @@ <maven.scm.version>1.11.2</maven.scm.version> <maven.site.path>${project.artifactId}-archives/${project.artifactId}-LATEST</maven.site.path> <project.build.outputTimestamp>1771315797</project.build.outputTimestamp> - <sling.feature.version>2.0.0</sling.feature.version> + <sling.feature.version>2.0.6</sling.feature.version> </properties> <dependencies> diff --git a/src/main/java/org/apache/sling/feature/maven/mojos/Aggregate.java b/src/main/java/org/apache/sling/feature/maven/mojos/Aggregate.java index 1610b99..8ab55b2 100644 --- a/src/main/java/org/apache/sling/feature/maven/mojos/Aggregate.java +++ b/src/main/java/org/apache/sling/feature/maven/mojos/Aggregate.java @@ -18,6 +18,7 @@ */ package org.apache.sling.feature.maven.mojos; +import java.io.File; import java.util.Collections; import java.util.LinkedHashMap; import java.util.List; @@ -74,6 +75,23 @@ public class Aggregate extends FeatureSelectionConfig { public Map<String, String> frameworkPropertiesOverrides; + /** + * Additional feature files to include in the aggregation, resolved at goal time + * rather than through the session-start Preprocessor scan.
