What it is

Easy Rules is a lightweight Java rules engine that lets you define business logic as discrete rule objects with conditions and actions, then execute them against a set of facts. It supports two programming models—annotation-based declarative rules (via @Rule, @Condition, @Action) and a fluent builder API—and can evaluate rules using expression languages like MVEL, SpEL, and JEXL. The core insight is that you don't need a heavy BRMS; just compose POJOs with condition/action pairs and iterate through them. Multi-module Maven monorepo: easy-rules-core/ contains the engine (API in org/jeasy/rules/api/, implementations in org/jeasy/rules/core/), and easy-rules-archetype/ provides a…

Start here

Open these first:

• easy-rules-core/src/main/java/org/jeasy/rules/api/RulesEngine.java — Core interface defining the rules engine contract; every contributor must understand the primary execution abstraction.
• easy-rules-core/src/main/java/org/jeasy/rules/core/DefaultRulesEngine.java — Default implementation of the rules engine; contains the main rule evaluation loop and execution logic.
• easy-rules-core/src/main/java/org/jeasy/rules/api/Rule.java — Core Rule interface defining condition/action pattern; fundamental abstraction for all rule definitions.
• easy-rules-core/src/main/java/org/jeasy/rules/core/RuleProxy.java — Reflection-based proxy for annotated rules; bridges annotation-based and interface-based rule definitions.
• easy-rules-core/src/main/java/org/jeasy/rules/annotation/Rule.java — Core annotation for declarative rule definition; primary entry point for users writing rules declaratively.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and build with Maven: git clone https://github.com/j-easy/easy-rules.git && cd easy-rules && mvn clean install. Then explore examples in easy-rules-archetype/src/main/resources/archetype-resources/ or create a…

Daily commands:

This is a library, not a runnable application. Build it: mvn clean install. To use it in your own project, add dependency: `<dependency><groupId>org.jeasy</groupId><artifactId>easy-rules-core</artifactId><version>4.1.…

Key cautions & unknowns

• Stale — last commit 2y ago
• Single-maintainer risk — top contributor 92% of recent commits
• No environment variables or external services required—Easy Rules is standalone. However, annotation processing depends on reflection at runtime, so rules must be on the classpath and discoverable by RuleProxy.…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
