Hello all,
I'm testing eclipse (oxygen 1a RC2 linux 64) and java 9 (oracle linux 64 release) and I'm encountering this issue. I have a maven project targeting java 8 with a simple pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>io.datarouter</groupId>
	<artifactId>j9mvn</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<properties>
		<maven.compiler.source>1.8</maven.compiler.source>
		<maven.compiler.target>1.8</maven.compiler.target>
	</properties>
</project>
with a simple class at src/main/java/j9mvn/Main.java
package j9mvn;
public class Main{
	public static void main(String[] args){
		System.out.println("Hello world");
	}
}
I imported the project in eclipse (File->Import...->Existing Maven Projects). When trying to run the main in eclipse I get:
Error: Could not find or load main class j9mvn.Main
Caused by: java.lang.ClassNotFoundException: j9mvn.Main
 
Eclipse project configuration looks ok: build path contains src/main/java as source folder and java 8 as library.
I see the class correctly generated at target/classes/j9mvn/Main.class
Any idea how to solve this issue?
