SAP Commerce Cloud 1811 and Eclipse project

[d_j_boyd]

I work on multiple projects 1811, 1905, and 2005. Each requiring different versions of java.

I have the latest version of Eclipse: 2020-09. It requires java 11. So changing the -vm argument in the ini file to anything but java 11 causes issues with eclipse, from not opening, to project explorer failing to load etc.

So my question is:

1811 is compatible with java 1.7 and 1.8. When I select in eclipse: Project -> build all, I can see in my console that things fail wit the following message:

**** WRONG JAVA VERSION ****
 Environment check failed: You are using a not supported version of Java. 
 Please make sure you are using Java version 1.7 or later.
 Your current Java version is: 11.0.1

 TIP: If you are using eclipse you can configure a different JVM under
 Preferences->Java->Installed JREs.
Total time: 692 milliseconds

I followed the TIP, but it did not make a difference.

I can run build.xml using the ant view - setting it up with the correct ant_home as well as the 1.8 JRE.

This issue is stopping me from being able to do debugging of the project as needed.

Any suggestions on how to resolve this issue>
