Quickstart: running Linea Besu with plugins

• compile linea-plugins gradlew installDist
• copy jar file to besu runtime plugins/ directory (where you will run Besu from, not where you're building Besu)
• add LINEA to besu config to enable the plugin RPC methods
  • rpc-http-api=["ADMIN","ETH","NET","WEB3","LINEA"]
• start besu (command line or from IDE) and you should see plugins registered at startup
• call the RPC endpoint eg:

  curl --location --request POST 'http://localhost:8545' --data-raw '{
    "jsonrpc": "2.0",
    "method": "linea_estimateGas",
    "params": [
      "from": "0x73b2e0E54510239E22cC936F0b4a6dE1acf0AbdE",
      "to": "0xBb977B2EE8a111D788B3477D242078d0B837E72b",
      "value": "0x123"
    ],
    "id": 1
  }'

./gradlew clean test

# Run only acceptance tests
./gradlew clean acceptanceTests

IntelliJ IDEA Setup

Enable Annotation Processing

• Go to Settings | Build, Execution, Deployment | Compiler | Annotation Processors and tick the following checkbox:

  

---

NOTE

This setting is required to avoid IDE compilation errors because of the Lombok library used for code generation of boilerplate Java code such as:

• Getters/Setters (via @Getter/@Setter)
• Class log instances (via @Slf4j)
• Builder classes (via @Builder)
• Constructors ( via @NoArgsConstructor/@RequiredArgsConstructor/@AllArgsConstructor)
• etc.

Install Optional Plugins

• Install Spotless Gradle plugin to re-format through the IDE according to spotless configuration.
