如何用Maven构建Corda应用并实现Cordform插件节点部署？

Hey there, I totally get where you're coming from—Corda's official docs and examples lean heavily on Gradle, so tracking down Maven equivalents for node deployment can feel like searching for a needle in a haystack. Let's fix that by replicating your Gradle deployNodes task using Maven and the Cordform Common plugin.

Step 1: Add the Cordform Common Plugin to Your pom.xml #

This plugin handles node deployment in Maven, just like the Gradle Cordform task. Here's the full configuration that maps directly to your Gradle code:

<build>
    <plugins>
        <!-- Cordform Common Plugin for node deployment -->
        <plugin>
            <groupId>net.corda.plugins</groupId>
            <artifactId>cordform-common</artifactId>
            <version>${corda.plugin.version}</version> <!-- Match your Corda release version -->
            <executions>
                <execution>
                    <id>deploy-nodes</id>
                    <phase>package</phase> <!-- Runs automatically after building your JAR -->
                    <goals>
                        <goal>deploy</goal>
                    </goals>
                    <configuration>
                        <!-- Equivalent to Gradle's `directory "./build/nodes"` -->
                        <outputDirectory>${project.build.directory}/nodes</outputDirectory>
                        <!-- Network Map node reference, matches Gradle's `networkMap` -->
                        <networkMapName>O=Controller,L=London,C=GB</networkMapName>
                        <!-- Node configuration block, mirroring Gradle's `node {}` -->
                        <nodes>
                            <node>
                                <name>O=Controller,L=London,C=GB</name>
                                <!-- Advertised notary service, same as Gradle's `advertisedServices` -->
                                <advertisedServices>
                                    <service>corda.notary.validating</service>
                                </advertisedServices>
                                <!-- P2P and RPC ports -->
                                <p2pPort>10002</p2pPort>
                                <rpcPort>10003</rpcPort>
                                <!-- Cordapps to include, matching Gradle's `cordapps` list -->
                                <cordapps>
                                    <cordapp>${project.group}:cordapp-contracts-states:${project.version}</cordapp>
                                    <cordapp>${project.group}:cordapp:${project.version}</cordapp>
                                    <cordapp>net.corda:corda-finance:${corda.release.version}</cordapp>
                                </cordapps>
                            </node>
                        </nodes>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Step 2: Configure Corda's Repository #

Make sure you've added Corda's official repository to your pom.xml so Maven can resolve the cordform-common plugin and Corda dependencies.

Key Notes to Match Your Gradle Setup #

• Execution Phase: The plugin runs in the package phase, which is Maven's way of ensuring it runs after building your JAR—just like Gradle's dependsOn: ['jar'].
• Output Directory: ${project.build.directory} defaults to target in Maven, so this will create nodes in target/nodes (you can adjust this path if needed, just like you did with ./build/nodes in Gradle).
• Version Placeholders: Replace ${corda.plugin.version} and ${corda.release.version} with your actual Corda version (e.g., 4.10 for recent stable releases).

Run the Deployment #

To deploy your nodes, simply run:

mvn package

This will trigger the plugin's deploy goal, generating all node files in the specified output directory—exactly what your Gradle deployNodes task does.
