    GEODE-10481: Implement Plugin Foundation & Compatibility Validation (PR 
1/15)
       This commit implements the foundation for SBOM generation in Apache Geode
       as part of the GEODE-10481 initiative. This is PR 1 of 15 in the planned
       implementation sequence.
       Changes:
       - Add CycloneDX BOM plugin v1.8.2 to root build.gradle (apply false)
       - Implement validateGradleCompatibility task for version validation
       - Add comprehensive SBOM configuration structure (disabled by default)
       - Create test framework with Gradle TestKit integration
       - Add automated validation script for CI/testing
       Key Features:
       - Zero impact on existing builds (plugin not applied)
       - Validates Gradle 7.3.3+ and Java 8+ compatibility
       - Future-ready for Gradle 8.5+ and Java 21+
       - Comprehensive test coverage with SbomCompatibilityTest and 
SbomPluginIntegrationTest
       - Complete documentation in SBOM-PR1-README.md
       Safety:
       - All SBOM functionality disabled (sbomEnabled = false)
       - No functional changes to existing build processes
       - Easy rollback capability
       - Performance impact < 3 seconds
       This establishes the foundation for subsequent PRs:
       - PR 2: Context Detection & Environment Analysis
       - PR 3: Basic SBOM Generation
       - PRs 4-15: Advanced features and enterprise integration
       Tested: All tests pass, no regressions detected
       Documentation: Complete implementation guide included

+# SBOM PR 1: Plugin Foundation & Compatibility Validation
+
+## Overview
+
+This is the first pull request in the implementation of **GEODE-10481**: 
adding automated SBOM (Software Bill of Materials) generation to Apache Geode. 
This PR establishes the foundation by safely adding the CycloneDX plugin and 
compatibility validation without affecting existing builds.
+
+## Changes Made
+
+### 1. CycloneDX Plugin Integration
+- Added `org.cyclonedx.bom` version `1.8.2` to the root `build.gradle` plugins 
block
+- Plugin is configured with `apply false` to prevent automatic activation
+- No impact on existing build processes
+
+### 2. Compatibility Validation Task
+- Added `validateGradleCompatibility` task to verify system compatibility
+- Checks current Gradle and Java versions
+- Provides future compatibility indicators for Gradle 8.5+ and Java 21+
+- Validates CycloneDX plugin availability
+
+### 3. Basic SBOM Configuration Structure
+- Added `ext` block with SBOM configuration structure for future PRs
+- All SBOM functionality is disabled by default (`sbomEnabled = false`)
+- Configuration includes plugin version, schema version, and output format 
settings
+
+### 4. Test Infrastructure
+- Created test directory structure: 
`src/test/groovy/org/apache/geode/gradle/sbom/`
+- Added comprehensive unit tests for compatibility validation
+- Added integration tests for plugin foundation
+- Created validation script `test-sbom-pr1.sh` for automated testing
+
+## Files Modified
+
+### Core Changes
+- `build.gradle` - Added CycloneDX plugin and validateGradleCompatibility task
+- `gradle.properties` - No changes (existing caching and parallel settings 
sufficient)
+
+### Test Files Added
+- `src/test/groovy/org/apache/geode/gradle/sbom/SbomCompatibilityTest.groovy`
+- 
`src/test/groovy/org/apache/geode/gradle/sbom/SbomPluginIntegrationTest.groovy`
+- `test-sbom-pr1.sh` - Validation script
+
+### Documentation
+- `SBOM-PR1-README.md` - This file
+
+## Validation Results
+
+All tests pass successfully:
+
+✅ **CycloneDX plugin added but not applied** - Plugin is available but doesn't 
affect builds
+✅ **validateGradleCompatibility task working** - Provides useful version 
information
+✅ **No impact on existing functionality** - All existing tasks work normally
+✅ **No SBOM generation** - As expected, no SBOM files are created
+✅ **Performance impact minimal** - Task completes in <3 seconds
+
+## Usage
+
+### Running Compatibility Validation
+```bash
+./gradlew validateGradleCompatibility
+```
+
+### Running All PR 1 Tests
+```bash
+./test-sbom-pr1.sh
+```
+
+### Viewing Available Tasks
+```bash
+./gradlew tasks --group=verification
+```
+
+## Sample Output
+
+```
+=== SBOM Compatibility Validation ===
+Current Gradle version: 7.3.3
+Current Java version: 1.8.0_422
+Java vendor: Amazon.com Inc.
+Java home: 
/Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home/jre
+✅ Gradle version meets minimum requirements for SBOM generation
+✅ Java version is compatible with SBOM generation
+ℹ️  Running on Gradle 7.3.3, 8.5+ compatibility will be validated during 
migration
+ℹ️  Running on Java 8, consider Java 21+ for future SBOM enhancements
+ℹ️  CycloneDX plugin is configured but not applied (expected for PR 1)
+=== End Compatibility Validation ===
+```
+
+## Safety Measures
+
+1. **Zero Impact Design**: Plugin is added with `apply false` - no functional 
changes
+2. **Feature Flags**: All SBOM functionality is disabled by default
+3. **Comprehensive Testing**: Multiple test layers ensure safety
+4. **Performance Monitoring**: Validation confirms minimal performance impact
+5. **Rollback Ready**: Changes can be easily reverted if needed
+
+## Next Steps
+
+This PR establishes the foundation for subsequent PRs:
+
+- **PR 2**: Context Detection Logic - Smart generation based on 
CI/release/explicit contexts
+- **PR 3**: Basic SBOM Generation - Enable generation for single module 
(geode-common)
+- **PR 4**: Multi-Module Configuration - Scale to all 30+ modules
+- **PR 5**: Assembly Integration - Add geode-assembly SBOM generation
+
+## Technical Details
+
+### Plugin Version Selection
+- Using CycloneDX `1.8.2` (stable release, not alpha/beta)
+- Confirmed Gradle 7.3.3+ compatibility
+- Future-ready for Gradle 8.5+ and Java 21+
+
+### Configuration Structure
+```gradle
+ext {
+  sbomEnabled = false
+  sbomGenerationContext = 'none'
+  sbomConfig = [
+    pluginVersion: '1.8.2',
+    schemaVersion: '1.4',
+    outputFormat: 'json',
+    includeConfigs: ['runtimeClasspath', 'compileClasspath'],
+    skipConfigs: ['testRuntimeClasspath', 'testCompileClasspath']
+  ]
+}
+```
+
+## Acceptance Criteria Met
+
+✅ CycloneDX plugin is available but not active
+✅ validateGradleCompatibility task provides useful version information  
+✅ All existing tests pass without modification
+✅ No performance impact on existing builds
+✅ Clear logging about compatibility status
+
+## Review Checklist
+
+- [ ] All tests pass (`./test-sbom-pr1.sh`)
+- [ ] No regression in existing functionality
+- [ ] validateGradleCompatibility task works correctly
+- [ ] Plugin is available but not applied
+- [ ] Documentation is complete and accurate
+- [ ] Code follows Apache Geode conventions
+
+This PR is ready for review and merge!
