Neo4j Server Maven Plugin

It may get hard to update the existing neo4j-maven-plugin and make it use the latest versions of Neo4j, because it depends on deprecated classes, which are very likely to be moved to some internal packages in the future.

So I decided to write another small Maven plugin, that simply downloads the complete Neo4j server artifact, and runs it, as a user would do it, using ./neo4j start

Furthermore it provides an idiomatic way to configure the server using the plugin <configuration> section.

Building the project

mvn clean install

Usage

start

mvn neo4j-server:start

stop

mvn neo4j-server:stop

Integration Testing

The start/stop goals bind by default to lifecycle phases pre- and post-integration-test:

<plugin>
    <groupId>com.github.harti2006</groupId>
    <artifactId>neo4j-server-maven-plugin</artifactId>
    <version>1.0-SNAPSHOT</version>
    <configuration>
        <port>${neo4j-server.port}</port>
        <version>${neo4j-server.version}</version>
    </configuration>
    <executions>
        <execution>
            <id>start-neo4j-server</id>
            <goals>
                <goal>start</goal>
            </goals>
        </execution>
        <execution>
            <id>stop-neo4j-server</id>
            <goals>
                <goal>stop</goal>
            </goals>
        </execution>
    </executions>
</plugin>

For an example, run

cd integration-tests
mvn clean verify

Parameters

Have a look at the Neo4jServerMojoSupport class for details.

Code Formatting

File formatting is verified by EditorConfig during mvn verify step. Most errors can be fixed with mvn editorconfig:format task.

Releases

The release process is copied frome this blog post:

• Snapshot releases to Maven Central are performed automatically by Travis CI on every push to master.
• Final releases to Maven Central are performed automatically by Travis CI after creating and pushing a git tag.
