Re: [m2e-users] java.lang.ClassNotFoundException with java9 and maven
Cool, that's a good news.

Thanks for the quick answer.

This is a bug in JDT[1]. You need to wait for a new build, in a day or 2.

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?
