Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
----

Gradle uses the JDK it finds in your path, the JDK used by your IDE, or the JDK specified by your project.
In this example, the $PATH points to JDK17:

----
❯ echo $PATH
/opt/homebrew/opt/openjdk@17/bin
----

You can also set the `JAVA_HOME` environment variable to point to a specific JDK installation directory.
This is especially useful when multiple JDKs are installed:

                </plugins>
            </build>
        </profile>
        <profile>
            <id>restrict-doclint</id>
            <!-- doclint is only supported by JDK 8 -->
            <activation>
                <jdk>[1.8,)</jdk>
            </activation>
            <build>
                <plugins>
                    <plugin>
                        <artifactId>maven-compiler-plugin</artifactId>

        }
    }
