(feat) Add embedded external policies for third-party dependency support#67
Conversation
…upport Modules can now ship policies for their runtime dependencies (e.g., Netty, Reactor) by placing them in src/main/jguard/. These policies are compiled to META-INF/jguard/external/*.bin in the JAR and automatically discovered by the agent alongside embedded policies. This enables applications to define capabilities for third-party libraries without requiring manual -Djguard.policy.override configuration at runtime. Same signing requirements apply as embedded policies. Changes: - Agent: Add external policy discovery from META-INF/jguard/external/*.bin in both JARs and directories (for development) - JarSignatureVerifier: Add findExternalPolicyEntries(), isEntrySigned(), and make hasSignatures() public - Gradle plugin: Default externalPoliciesSourceDir to src/main/jguard/ (mirrors src/test/jguard/ for test policies) - Gradle plugin: Output external policies to build/jguard-policy/META-INF/ jguard/external/ so they're packaged in JARs - Gradle plugin: Add compileTestJava dependency on compileExternalPolicies to fix Gradle task dependency validation error - Add comprehensive tests for external policy discovery Signed-off-by: Nicholas Walter Knize <nknize@apache.org>
