commit 6bbd22d877025f7567aae45df9b5a5e45be96f70 Author: Lukasz Lenart <[email protected]> AuthorDate: Sat Jan 10 14:12:11 2026 +0100 fix(facet): populate file sets when framework is detected - Add setupFacet() override to StrutsFrameworkDetector to automatically add detected struts.xml files to file sets when user clicks "Configure" - Fix key mismatch in StrutsFrameworkInitializer (was storing with project.getName() but retrieving with project.getLocationHash()) - Fix NPE in StrutsFrameworkInitializer fallback logic that called performInitialization with null facet - Refactor framework initialization to use modern ProjectActivity pattern - Update various files for IntelliJ Platform 2025.3 compatibility 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]> --- CLAUDE.md | 413 +++++-------------- docs/framework-initialization.md | 446 +++++++++++++++++++++ .../com/intellij/lang/ognl/OgnlTypedHandler.java | 4 +- .../ognl/psi/impl/OgnlReferenceExpressionBase.java | 4 +- .../intellij/struts2/facet/StrutsFacetType.java | 63 +-- .../struts2/facet/StrutsFrameworkDetector.java | 46 +++ .../struts2/facet/StrutsFrameworkInitializer.java | 266 ++++++++++++ .../facet/StrutsFrameworkSupportProvider.java | 135 +------ .../struts2/facet/ui/FileSetConfigurationTab.java | 7 +- .../contributor/StrutsCoreConstantContributor.java | 4 +- src/main/resources/META-INF/plugin.xml | 3 + 11 files changed, 911 insertions(+), 480 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index 7734a7f..5b0707d 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -5,351 +5,140 @@ This file provides guidance to Claude Code (claude.ai/code) when working with co ## Development Commands ### Build and Test -- `./gradlew build` -

Update this guide with any new findings or issues -3. Document any plugin-specific compatibility fixes - -### Common Issues & Solutions - -**Java Version Mismatch** -- Error: `sourceCompatibility='17' but IntelliJ Platform requires sourceCompatibility='21'` -- Solution: Update `jvmToolchain()` in `build.gradle.kts` and all GitHub Actions workflows - -**Qodana Version Warnings** -- Error: `You are running a Qodana linter without an exact version tag` -- Solution: Update `qodana.yml` with specific linter version matching platform - -**API Compatibility Issues** -- Error: `cannot find symbol` for removed methods -- Solution: Check API changes documentation and replace with compatible alternatives - -**DOM Test Path Resolution Issues** -- Error: `Cannot find source file: .../ideaIU-2024.2/.../testData/stubs/file.xml` -- Root Cause: IntelliJ Platform 2024.2 test framework changed path resolution behavior -- Solution: Update test classes extending `DomStubTest` to override both `getBasePath()` and `getTestDataPath()`: - ```java - @Override - protected String getBasePath() { - return "src/test/testData/stubs"; // Use project-relative path - } - - @Override - protected String getTestDataPath() { - return "src/test/testData/stubs"; // Ensure consistent resolution - } - ``` - -**Kotlin K2 Mode** -- Java-based plugins automatically support K2 mode (no migration needed) -- If using Kotlin APIs, may need migration to Analysis API - -**JSP Reference Provider Failures (IntelliJ 2024.2)** -- **Issue**: Tests fail with "no reference found" errors for JSP action links -- **Root Cause**: `javaee.web.customServletReferenceProvider` extension point API changed in IntelliJ 2024.2 -- **Affected Classes**: `ActionLinkReferenceProvider` extending `CustomServletReferenceAdapter` -- **Working**: Local inspections still work (e.g., `HardcodedActionUrlInspectionTest` passes) -- **Diagnosis**: Web/JSP facet setup works; issue is specifically with reference provider registration -- **Plugin Registration**: Extension point `<javaee.web.customServletReferenceProvider implementation="com.intellij.struts2.reference.jsp.ActionLinkReferenceProvider"/>` may need alternative approach -- **Status**: 94% tests pass, but JSP reference resolution needs API migration research -- **Future Work**: Research IntelliJ 2024.2 web reference provider APIs; consider migrating to standard `psi.referenceProvider` extension points - -**Error Message Format Changes (IntelliJ 2024.2)** -- **Issue**: Highlighting tests fail due to changed error message formats -- **Examples**: - - "Cannot resolve symbol" → "Cannot resolve file" - - Multiple error types for same element: `descr="Cannot resolve file '...'|Cannot resolve symbol '...'"` -- **Affected**: StrutsResultResolvingTest, various highlighting tests -- **Solution**: Update test data files with new error message formats using pipe separator for multiple errors -- **Character Position Precision**: IntelliJ 2024.2 requires exact character position matching for error annotations - -**StrutsResultResolvingTest Improvements (IntelliJ 2024.2)** -- **Status**: Improved from 62% to 75% success rate (5/8 → 6/8 tests passing) -- **Fixed**: `testActionPath` - Updated `struts-actionpath.xml` with correct error annotation formats -- **Remaining Issues**: `testPathDispatcher` and `testActionPathFQ` require complex character positioning fixes -- **Updated Files**: - - `src/test/java/com/intellij/struts2/dom/struts/StrutsResultResolvingTest.java` - Added IntelliJ 2024.2 compatibility documentation - - `src/test/testData/strutsXml/result/struts-actionpath.xml` - Fixed combined error annotations -- **Key Learning**: IntelliJ 2024.2 generates separate error annotations instead of combined pipe-separated formats -- **Documentation**: Added comprehensive JavaDoc explaining new error message requirements for future maintenance - -**OGNL Lexer Test Failures (IntelliJ 2024.2) - FIXED** ✅ -- **Issue**: 4 OgnlLexerTest failures related to test data path resolution -- **Affected Tests**: `testTwoRightCurly`, `testNestedModuloAndCurly`, `testNestedBracesWithoutExpression`, `testNestedBraces` -- **Root Cause**: IntelliJ Platform 2024.2 changed `LexerTestCase` path resolution behavior -- **Framework Behavior**: Test framework looked in `/Users/.../ideaIU-2024.2-aarch64/testData/lexer/` instead of `src/test/testData/lexer/` -- **Fix Applied**: Updated `OgnlLexerTest.getDirPath()` method to return `"src/test/testData/lexer"` directly instead of using `OgnlTestUtils.OGNL_TEST_DATA + "/lexer"` -- **Status**: ✅ All 4 tests now pass (verified in test run) -- **Files Modified**: `src/test/java/com/intellij/lang/ognl/lexer/OgnlLexerTest.java:59` - -**JSP OGNL Injection Test Failure (IntelliJ 2024.2) - FIXED** ✅ -- **Issue**: `Struts2OgnlJspTest.testStruts2TaglibOgnlInjection` failed with unexpected URL highlighting in license header -- **Root Cause**: IntelliJ Platform 2024.2 enhanced URL detection, now highlighting `http://www.apache.org/licenses/LICENSE-2.0` in ASF license header with "Open in browser" functionality -- **Solution**: Updated test to disable info-level highlighting checks by changing `myFixture.testHighlighting(true, true, false, ...)` to `myFixture.testHighlighting(true, false, false, ...)` -- **Rationale**: Test should focus on OGNL injection functionality, not general IDE URL detection in license headers -- **Status**: ✅ Fixed and verified passing -- **Files Modified**: `src/test/java/com/intellij/struts2/jsp/ognl/Struts2OgnlJspTest.java:55` - -### Migration Resources -- [IntelliJ Platform Migration Guide](https://plugins.jetbrains.com/docs/intellij/tools-intellij-platform-gradle-plugin-migration.html) -- [API Changes List](https://plugins.jetbrains.com/docs/intellij/api-changes-list-2024.html) -- [Platform Gradle Plugin 2.0](https://blog.jetbrains.com/platform/2024/07/intellij-platform-gradle-plugin-2-0/) -- [Build Number Ranges](https://plugins.jetbrains.com/docs/intellij/build-number-ranges.html) -``` +**JSP Reference Providers**: The `javaee.web.customServletReferenceProvider` extension point behavior changed in 2024.2.
