Re: Sweet Home 3D JS Online
Finally, the error under Windows can be fixed easily: in build.xml Ant file, just replace colons (:) in the two following lines
<arg value="../SweetHome3D/src:tools/JSweet/src" />
<arg value="def:com/eteks/sweethome3d/model:com/eteks/sweethome3d/tools:com/eteks/sweethome3d/viewcontroller:com/eteks/sweethome3d/io" />
by ${path.separator} (see fix here).

By the way, if you want to generate SweetHome3DJS.war file, don't forget to run Ant default target in SweetHome3D project too. SweetHome3D.jar is required to generate the war file.

Re: Sweet Home 3D JS Online
Hello, AMAZING STUFF Puybaret.

I have been having issues building the war file for SweetHome3DJS.

the .jar for SweetHome3D builds successfully, but all the ant commands fail for SweetHome3DJS

BUILD FAILED

Re: Sweet Home 3D JS Online
As you didn't report the error, it's difficult to help you.
Did you read the discussion with emirhanbskc which might help you?

Re: Sweet Home 3D JS Online
Hello, yes, I read the discussion, i have done everything in the readme, everything else builds, am I meant to put the sweethome3d.jar in any particular folder after building it?

How do i report the error, can i put a log here?

this is where the error starts:

Re: Sweet Home 3D JS Online
Building Sweet Home 3D JS project requires JDK 8, and not a further version. Is it your case?
[Note that building recent versions requires JDK 11, not JDK 8]

Re: Sweet Home 3D JS Online
yes please, my mac uses jdk 8. Do I have to put the sweethome3d.jar in any specific folder to aid the building?

Re: Sweet Home 3D JS Online
I'm pretty sure you're not using JDK 8 to build the project. I just tried with JDK 15 and got the same error. If you use Terminal, set JAVA_HOME environment variable to ensure Ant uses the right JDK.
Do I have to put the sweethome3d.jar in any specific folder to aid the building?
No, just leave it in its default place, but SweetHome3D and SweetHom3DJS projects must be in the same folder.

Re: Sweet Home 3D JS Online
It's strange because even if try (resource) { } syntax is allowed only from Java 7, your server seems to use a JDK 8. Maybe try to run the server with JDK 11.
