+# Fix `java:S1874`: Remove this use of "getBaseDir"; it is deprecated.
+
+## Description
+
+SonarQube for IDE detected a code quality issue.
+
+- **Rule:** `java:S1874`
+- **File:** `src/test/java/com/devoxx/genie/service/agent/tool/BuiltInToolProviderTest.java`
+- **Line:** 51
+- **Severity:** Low impact on Maintainability
+- **Issue:** Remove this use of "getBaseDir"; it is deprecated.
+
+## Task
+
+Fix the SonarQube issue `java:S1874` at line 51 in `src/test/java/com/devoxx/genie/service/agent/tool/BuiltInToolProviderTest.java`.
+
+## Acceptance Criteria
+
+- [x] Issue `java:S1874` at `BuiltInToolProviderTest.java:51` is resolved
+- [x] No new SonarQube issues introduced by the fix
+- [x] All existing tests continue to pass
+
+## Implementation Notes
+
+Removed the deprecated `project.getBaseDir()` call from `setUp()` at line 51. Investigation showed that:
+- `BuiltInToolProvider` never calls `getBaseDir()` — it only passes the `Project` to tool executors
+- All tool executors use `ProjectUtil.guessProjectDir(project)` or `project.getBasePath()` instead
+- The `projectBase` mock field and `VirtualFile` import were also unused and removed
+
+**Files modified:** `src/test/java/com/devoxx/genie/service/agent/tool/BuiltInToolProviderTest.java`
+
+**Changes:**
+1. Removed `import com.intellij.openapi.vfs.VirtualFile` (unused after fix)
+2. Removed `@Mock private VirtualFile projectBase` field (only used in deprecated call)
+3. Removed `when(project.getBaseDir()).thenReturn(projectBase)` line (the deprecated API call)
+
+All 13 tests in `BuiltInToolProviderTest` pass after the change.
