Is the maven-release plugin compatible with Java 9?

I just tried to release my Java compatible project with maven-release-plugin. However maven-compiler-pluginfailed to execute

Failed to fulfill target org.apache.maven.plugins: Maven-compiler-plugin: 3.7.0: compile (default compilation) in project email: Fatal error compiling: invalid target version: 9

It's funny that it maven-compiler-pluginworks great if I run it autonomously. My setup:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <source>9</source>
                <target>9</target>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <version>2.5.3</version>
            <configuration>
                <autoVersionSubmodules>true</autoVersionSubmodules>
                <tagNameFormat>v@{project.version}</tagNameFormat>
            </configuration>
        </plugin>

Maven version 3.5.0.

mvn clean install works fine;

mvn release:prepare release:perform -DignoreSnapshots=true not performed with exceeded exception.

Debug output:
