Eclipse Warning "Build path specifies execution environment JavaSE-17."-CodePudding

I am taking a udemy course "Selenium Webdriver with Java for Beginners" and have done all of the setup from the course, but I cannot for the life of me get rid of this warning in eclipse. I verified I have java18.0.1.1 installed on my mac, edited the build path in eclipse to point to the 18.0.1.1 jdk. The issue is, the JRE system library keeps reverting to JavaSE-17, which afaik isnt installed on my machine. It happens every time I click update maven project.

In my pom.xml file, I have the below maven plugin, specifying java18...

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.10.1</version>
        <configuration>
          <source>18</source>
          <target>18</target>
        </configuration>
</plugin>

Build path specifies execution environment JavaSE-17. There are no JREs installed in the workspace that are strictly compatible with this environment.

Try to check this block in your pom.xml.

  <properties>
    ...
    <maven.compiler.source>18</maven.compiler.source>
    <maven.compiler.target>18</maven.compiler.target>
  </properties>

If it doesn't work check the official manual about Maven's POM.xml here

Make sure that you also have a correct Maven path at your Mac.

Use of Java 18 requires both Eclipse 2022-03 and this patch from the Marketplace. 2022-03 came out a week before Java 18 (March 16th vs. March 22nd), so it can not officially claim to support it. The patch should be uninstalled before updating to 2022-06 later this month.
