this is the version of Java that I have on my machine
index.php/fa/34295/0/

and this is the version of maven on my machine
index.php/fa/34296/0/

I think that on my installation is missing something, but honestly for the moment I don't know what.
Suggestion are welcome

Thanks in advance for any help

Marco

Hey man,

maybe this link might be help you to find a solution. Either your installed JDK or the Maven Compiliation might be the thing.

Hi there

I think The Maddes is correct: It sounds like you compiled the application on a newer Java version and run it on an older version.
Unless you specify that you want to target an older version, the compiler will target the version you compile it on -- which can't be read by older versions.


  • Version 54 (the version you compiled it with) corresponds to Java 10
  • Version 52 (the version you run it with) corresponds to Java 8


Please note: Eclipse Scout may not run out-of-the-box with a JDK version greater than Java 8.
You may need to set your Eclipse to run with the JDK 8 as described in the Beginners Guide Appendix (towards the end of section B.3).

Hi,
my Eclipse Photon is set to use JDK 1.8
index.php/fa/34297/0/

This is enough or not?

What is in your project pom.xml?
For me its: 
<properties>
    <jdk.source.version>1.8</jdk.source.version>
    <org.eclipse.scout.rt.version>8.0.0.021_Simrel_2018_09</org.eclipse.scout.rt.version>
  </properties>


Maybe thats a point to step into?
