appengine-maven-plugin configuration options like jvm flags

Question

Since version 1.7.4. of Google App Engine the official appengine-maven-plugin is released by Google. It has a task appengine:devserver to start the local development server.

This plugin seems not to have any Maven configuration options.

I wonder how I can a) provider jvm flags b) to disable new version check (when working offline)

Note that until now I was using the unofficial net.kindleit maven-gae-plugin like:

<plugin>
    <groupId>net.kindleit</groupId>
    <artifactId>maven-gae-plugin</artifactId>
    <version>0.9.4</version>
    <configuration>
        <disableUpdateCheck>true</disableUpdateCheck>
        <javaAgent>${env.REBEL_HOME}/jrebel.jar</javaAgent>
        <jvmFlags>
            <jvmFlag>-noverify</jvmFlag>
            <jvmFlag>-Ddatastore.backing_store=${project.basedir}/local_db.bin</jvmFlag>
            <jvmFlag>-Ddatastore.default_high_rep_job_policy_unapplied_job_pct=20</jvmFlag>
            <jvmFlag>-Drebel.spring_data_plugin=true</jvmFlag>
        </jvmFlags>
        <wait>true</wait>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>com.google.appengine</groupId>
            <artifactId>appengine-tools-sdk</artifactId>
            <version>${com.google.appengine.version}</version>
        </dependency>
        <dependency>
            <groupId>com.google.appengine</groupId>
            <artifactId>appengine-api-1.0-sdk</artifactId>
            <version>${com.google.appengine.version}</version>
        </dependency>
    </dependencies>
</plugin>

I wrote the plugin, so I guess this is my fault. The configuration is well supported for appcfg operations (like update/rollback/etc.), but I need to fix a few things obviously for the development server. I'll get onto that and there should be an update soon.

UPDATE : I've pushed a snapshot build that supports configuration for the devserver target. It's in 1.7.5-SNAPSHOT.
