After installing the extension on vscode, if the path to digized.umple-{version} has a whitespace somewhere in the middle (usually caused by the user's root folder having a whitespace, e.g. My User), the jar xf command will take the path as two different arguments, and thus causes the extension not being able to find umple.jar.

Specifically, this produces the following error:

Activating extension 'digized.umple' failed: Command failed: cd c:\Users\My User\.vscode\extensions\digized.umple-1.2.1 && jar xf c:\Users\My User\.vscode\extensions\digized.umple-1.2.1\umple.jar en.error
java.util.zip.ZipException: zip END header not found
	at java.base/java.util.zip.ZipFile$Source.findEND(ZipFile.java:1618)
...
	at jdk.jartool/sun.tools.jar.Main.main(Main.java:1700)

Which cause the extension to have no callable actions:

And force-calling the actions with Ctrl + Shift + P will result in a command not found error:
