IntelliJ IDEA - Maven Can't Find JAVA_HOME After Java 11 Install

I'm running IntelliJ IDEA on Ubuntu 18.04. I've just installed Java 11 and have updated my .bashsrc file to set JAVA_HOME to the new JDK. In the terminal I can run mvn clean install and it will build my d fine. But in the IntelliJ terminal window, I get the following error when running a mvn clean install

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

In the IntelliJ terminal window this is the result of echo $JAVA_HOME

/usr/lib/jvm/java-11

Similarly, this is the result of echo $PATH

/home/myusername/.local/bin:/home/myusername/.local/bin:
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:
/usr/local/games:/snap/bin:/usr/lib/jvm/java-11/bin:
/usr/lib/jvm/java-11/db/bin:/usr/lib/jvm/java-11/bin:/usr/lib/jvm/java-11/db/bin

What do I need to do to have IntelliJ's version of maven recognize JAVA_HOME? I've already set my Project SDK to JDK11.

Go to the Preferences > Build Tools > Maven > Runner, and set the JAVA_HOME property manually.

you may need to update your "maven-javadoc-plugin" version.

  <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-javadoc-plugin</artifactId>
            </plugin>
        </plugins>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-javadoc-plugin</artifactId>
                    <version>3.3.0</version>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

I had almost the same issue, except my Java version was shown as 1.8 after typing mvn -v in IDEA, but JAVA_HOME value was empty while it displayed correctly in Linux terminal. I`ve typed the following command in IDEA terminal 

export JAVA_HOME=*path to Java 11*

This solved my problem. I think you could try the same without reinstall both Java and Maven.

I messed around with this for a couple of hours yesterday but was unable to resolve the issue. In the end, I completely uninstalled both Java and Maven and then reinstalled JDK8 and the latest Maven. This appeared to fix the problem in that IntelliJ's command line was able to locate JAVA_HOME.

Here are the two resources I used to uninstall all Java and then reinstall JDK8, for anyone who is interested.

How to completely uninstall Java

How to install JDK on Ubuntu

I've yet to reinstall JDK11.
