+# LSN-0039: Jenkins + JaCoCo Integration with Multi-Module Gradle
+
+- **Problem:** O Jenkinsfile estava desatualizado, tentando rodar uma task de cobertura inexistente (`testCodeCoverageReport`) em um subprojeto específico, ignorando a cobertura global e causando falhas no pipeline.
+- **Decision:** Alinhar o `Jenkinsfile` com a task de agregação customizada no root project (`jacocoTestReport`), removendo a dependência de subprojetos específicos para métricas globais.
+- **Implementation:**
+    - Atualizado o comando de execução no Jenkins: `./gradlew clean test jacocoTestReport`.
+    - Ajustado o `recordCoverage` para ler o XML consolidado em `build/reports/jacoco/jacocoTestReport/jacocoTestReport.xml`.
+    - Ajustado o `publishHTML` para exibir o relatório consolidado em `build/reports/jacoco/jacocoTestReport/html`.
+- **Example:**
+    - Antes: `SRS_APP/build/reports/...` (específico por app).
+    - Depois: `build/reports/...` (global do projeto).
+- **Pitfalls:**
+    - Ao usar relatórios consolidados no root, deve-se garantir que o Gradle rode a task de agregação *após* os testes de todos os subprojetos.
+    - O Jenkins precisa de acesso ao workspace root para encontrar esses arquivos; caminhos relativos no `Jenkinsfile` geralmente partem do root do checkout.
+- **References:**
+    - `DSC-0024`, `DEC-0025`, `PLN-0048`.
