I have 2 DSLs. When I launch the 2nd instance of Eclipse only 1 of them is active. [message #1853505]

Hi again,

I'm still trying to pick up where I left off about 4 years ago.

So, as the title indicates, my project has 2 different DSLs but only one of them is getting launched when I run Eclipse. I don't know where to look for this info.

index.php/fa/42266/0/

The language infrastructure builds without error in both cases.

index.php/fa/42269/0/

Here are the properties in the new Eclipse. Notice that "SpinCAD" is missing.

can you check the launch configuration if you select all dsls, if it shows errors for dsls?
can you check the plugin.xml_gen / plugin.xml files if there first is properly merged to second
in the runtime eclipse can you check the host osgi console (+ button in console view) and type "ss spin" there
if your spin plugins are not active can you then type start <id of non active plugin>

Thanks for the response. I'm not entirely sure what you meant by some of your questions but I'll show you what I think you are asking for.

index.php/fa/42272/0/

xml (one that's not working)

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

<plugin>

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.holycityaudio.com/spincad/SpinCAD" 
       class = "com.holycityaudio.spincad.spinCAD.SpinCADPackage"
       genModel = "model/generated/SpinCAD.genmodel" /> 
	
  </extension>



</plugin>

xml-gen

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

<plugin>

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.holycityaudio.com/spincad/SpinCAD" 
       class = "com.holycityaudio.spincad.spinCAD.SpinCADPackage"
       genModel = "model/generated/SpinCAD.genmodel" /> 
	
  </extension>



</plugin>

OK the other plugin xml (the one that works) is totally different.

index.php/fa/42274/0/

xml-gen

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

<plugin>

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.holycityaudio.com/spincadmenu/SpinCADMenu" 
       class = "com.holycityaudio.spincadmenu.spinCADMenu.SpinCADMenuPackage"
       genModel = "model/generated/SpinCADMenu.genmodel" /> 
	
  </extension>



</plugin>

Maybe this?

Makes no sense though.

yes you use java 18 there, for reason i dont know, but launch with java 6 for another reason i dont know

xtext supports java 8 and 11 officially and can run with java 17 as target

as i said:
lauch the runtime
check the host osgi console.

also check the plugin.xml and plugin.xml_gen
contents text wise and compare them.

Yeah, I don't know why I selected this that or the other thing either. I'm pretty sure I selected Java 18 because that's what is on my PC at the moment. There are many places to set this, I guess... too many?
I haven't used OSGI console before, looks like some effort is required to set that up... will be back later.

Thanks!

Great, thanks, I appear to be past that issue.

Default JRE in Eclipse Preferences is shown:

index.php/fa/42282/0/

After I added this, my second DSL appears to be active.

But why did you configure the project to use 18
(Manifest)
Maybe you wanted 1.8

As far as using Java 18, I'm just trying to stay current with what is out there.
I am not a full time or professional developer. This is just a hobby.
So at least half of what I am doing is just guessing and hoping for the best.
I thank you very much for your assistance!!!
