https://issues.apache.org/jira/browse/SOLR-18338 Adds opt-in JaCoCo test coverage to the Gradle build, modeled on the equivalent integration in Apache Lucene. ## What was done * New `gradle/testing/coverage.gradle`, applied from the root build. Coverage is **opt-in**: it activates when running the `coverage` task or passing `-Ptests.coverage=true`; regular builds are unaffected. * Per module: the built-in `jacoco` plugin instruments the test tasks and `jacocoTestReport` produces HTML + XML reports (XML is what CI tooling consumes). * Root: `jacoco-report-aggregation` provides an aggregated report across all modules with tests via `gradlew coverage`. * Console summaries via the `org.barfuin.gradle.jacocolog` plugin (same as Lucene) — per-module and aggregated coverage percentages are printed at the end of the build. * Test security policy: granted the jacoco agent write access to its data file, so coverage also works when tests run with the security manager enabled. * The `tests.coverage` option shows up in `gradlew testOpts`; usage documented in `dev-docs/gradle-help/tests.txt`. ## Usage ``` gradlew -p solr/core coverage # single module open solr/core/build/reports/jacoco/test/html/index.html gradlew -p solr/core test --tests TestDemo coverage # with test filtering gradlew coverage # all tests + aggregated report open build/reports/jacoco/testCodeCoverageReport/html/index.html ``` Follow-up (separate effort): publish nightly coverage from the Jenkins job and add PR-level diff-coverage feedback. -- This is an automated message from the Apache Git Service.
