Sweet Home 3D JS Online

[Puybaret]

Finally, the error under Windows can be fixed easily: in build.xml Ant file, just replace colons (:) in the two following lines

Code: Select all

<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 [font=courier new]${path.separator}[/font] (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.

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
/Users/sweethome3d-code-r7868-trunk/SweetHome3DJS/build.xml:88: The following error occurred while executing this line:

As you didn't report the error, it's difficult to help you.
Did you read the discussion with emirhanbskc which might help you?

[chukwu]

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:

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]

[chukwu]

yes please, my mac uses jdk 8. Do I have to put the sweethome3d.jar in any specific folder to aid the building?

[Puybaret]

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 [font=courier new]JAVA_HOME[/font] 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.

[chukwu]

Thanks alot, I eventually used my windows compartment to build it. It works!

Can you help me ?

[Puybaret]

It's strange because even if [font=courier new]try (resource) { }[/font] syntax is allowed only from Java 7, your server seems to use a JDK 8. Maybe try to run the server with JDK 11.
