Aion4j maven plugin provides build and deployment support for AVM based smart contracts.

Following maven goals has been implemented in this plugin :

  1. aion4j:clean - Default phase for this goal is "clean". To clean storage folder in case of embedded AVM deployment.
  2. aion4j:deploy - Deploy the contract / dapp jar to an embedded AVM. This goal needs to invoked explicitely from the command line.
  3. aion4j:call - Call contract method
  4. aion4j:contract-txn
  5. aion4j:init - Default phase for this goal is "initialize". It initializes the project with required AVM dependencies. Currently it copies all required avm jars to a lib folder under project's folder. You can also manually create this lib folder or point to an existing avm lib folder through the plugin's configuration parameter.
  6. aion4j:prepack - Default phase "prepare-package". Copy org-aion-avm-userlib.jar's classes to target folder for packaging with dapp's jar.
  7. aion4j:class-verifier - To verify JCL whiltelist classes in the contract
  8. aion4j:deploy - Extend the deploy goal for remote deployment.
  9. aion4j:postpack - Post process the jar after build. Example: Abi Compile to process @Callable annotation. Default phase "package"
  10. aion4j:get-receipt - Get the receipt for a transaction hash
  11. aion4j:get-logs - Get logs
  12. aion4j:transfer - Transfer aion coins from one account to another.
  13. aion4j:get-balance - Get balance of an account. 14: aion4j:account - Create and manage account, topup account with test Aion tokens.
  14. aion4j:create-invokable - Create invokable transaction (meta-transaction)
  15. aion4j:generate-js-client - Generate javascript client code to invoke the smart contract.
  16. aion4j:generate-test-support - Generate helper classes for unit test.

"mode" can be local or remote.

  1. Add avm compile and test time dependencies to "<dependencies>" section.
    <dependency>
       <groupId>org.aion</groupId>
       <artifactId>avm-api</artifactId>
       <version>0.0.0</version>
       <scope>system</scope>
       <systemPath>${avm.lib.dir}/org-aion-avm-api.jar</systemPath>
     </dependency>
     <dependency>
        <groupId>org.aion</groupId>
        <artifactId>avm-userlib</artifactId>
        <version>0.0.0</version>
        <scope>system</scope>
        <systemPath>${avm.lib.dir}/org-aion-avm-userlib.jar</systemPath>
     </dependency>
     <dependency>
         <groupId>org.aion</groupId>
         <artifactId>avm-tooling</artifactId>
         <version>0.0.0</version>
         <scope>system</scope>
         <systemPath>${avm.lib.dir}/org-aion-avm-tooling.jar</systemPath>
      </dependency>

      <!-- Test dependencies -->
      <dependency>
         <groupId>junit</groupId>
         <artifactId>junit</artifactId>
         <version>4.11</version>
         <scope>test</scope>
      </dependency>
      <!-- Don't change the following dependency. This is required to compile & run test cases. The avm.jar for the project will be
        installed into the local maven repository during mvn initialize phase. -->
      <dependency>
          <groupId>${groupId}</groupId>
          <artifactId>${artifactId}-avm</artifactId>
          <version>${version}</version>
          <scope>test</scope>
      </dependency>

Note: The above jars will be copies to "avm.lib.dir" using maven initialize (or through aion4j:init goal) if not there.

How to use in a Smart Contract maven project (Embedded Avm or local mode)

  1. Copy required avm dependencies.
$>mvn initialize
  1. Build the project
$>mvn clean package
  1. To deploy to an embedded AVM
$>mvn aion4j:deploy

For Remote deployment (Remote mode or Aion Kernel)

For deployment and testing on Aion Kernel, add a new profile for remote mode under profiles section in pom.xml.

<profiles>
       ...
        <profile>
            <id>remote</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.aion4j</groupId>
                        <artifactId>aion4j-maven-plugin</artifactId>
                        <version>${aion4j.plugin.version}</version>
                        <configuration>
                            <mode>remote</mode>
                            <avmLibDir>${avm.lib.dir}</avmLibDir>
                            <web3rpcUrl></web3rpcUrl>
                        </configuration>
                        <executions>
                            <execution>
                                <goals>
                                    <goal>clean</goal>
                                    <goal>init</goal>
                                    <goal>prepack</goal>
                                    <goal>class-verifier</goal>
                                    <goal>postpack</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>
