Maven: invalid target release: 12, but JAVA_HOME is set to 12

Arthur :

invalid target release: 12

mvn -version Apache Maven 3.6.1

Here is my JAVA

# which java
/usr/bin/java
# java -version
openjdk version "12.0.2" 2019-07-16

And pom.xml code

<properties>
    <maven.compiler.source>12</maven.compiler.source>
    <maven.compiler.target>12</maven.compiler.target>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>                    <useIncrementalCompilation>true</useIncrementalCompilation>
                <compilerArgs>
                    <arg>-parameters</arg>
                    <arg>-Xlint:unchecked</arg>
                    <arg>--enable-preview</arg>
                </compilerArgs>
            </configuration>
        </plugin>

How ot achieve normal build?

Phash :

You need to reference the Version in the plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>12</release> 
    </configuration>
</plugin>
