On macOS Catalina 10.15.4, I have jdk-10.0.1 installed.
When I go to the Terminal and type in:
echo $JAVA_HOME
stdout:

Calculator class:
package com.sample;
public class Calculator {
public static int add(int a, int b) {
return a + b;
}
}
JUnit 5 test:
package com.sample;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;
public class CalculatorTest {
@Test
public void add() {
assertEquals(5, Calculator.add(2, 2));
}
}
When I run it via Terminal or IntelliJ IDEA Ultimate Edition 2019.3 (as a Maven run config mvn test), I get the following error:

CrazyCoder :
Java source/target version specified as 10.0.1 is not supported. You should use the major version only like 10 instead:
<java.version>10</java.version>
<maven.compiler.source>10</maven.compiler.source>
<maven.compiler.target>10</maven.compiler.target>
<configuration>
<release>10</release>
</configuration>
In IntelliJ IDEA open pom.xml file, press Ctrl+R (Alt/Option+R on macOS) for Replace action, type 10.0.1 in the search field, Tab, type 10 in the replace field, Alt+A for Replace All.
