Is maven-release-plugin compatible with Java 9?

I just tried to release my Java 9 compatible project with maven-release-plugin. However, it failed in maven-compiler-plugin with

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project email: Fatal error compiling: invalid target release: 9

Funny thing is that maven-compiler-plugin works fine in case I run it standalone. 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 fails with above exception.

Debug output:

========== If you use heroku ===========

Go to system.properties and set:

java.runtime.version=9

Also add the following to the pom.xml for maven:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.2</version>
    <configuration>
        <source>9</source>
        <target>9</target>
    </configuration>
</plugin>

Check this out.

According to the Java+9+-+Jigsaw which was updated very recently there is no change required or desired in the maven-release-plugin to be compatible with JDK9.

Additionally from the logs shared in the question the output in your case seems to be because of a misconfigured Maven with Java version less than 9.

While I was facing a similar issue, I had noticed that the java version used by Maven when executed using sudo and normally on command prompt were different.

To stick to consistent version of java used by maven make sure you have a mavenrc configured. You can do that in a similar way to this:

vi ~/.mavenrc

and then save it with content as follows:

export PATH
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
export PATH=${PATH}:$JAVA_HOME/bin

Execute 

mvn -version

and make sure its output is consistent via both command prompt and intelliJ terminal.
