"The plugin archive file cannot be extracted" without obvious error

IntelliJ Platform Plugin Verifier
1

The plugin verifier now complains about “The plugin archive file cannot be extracted.” and I don’t understand why.
This used to work before, but this is on a new major version of the plugin.
I can install the ZIP into IntelliJ IDEA without problems.
zipinfo is not showing any error.

I also tried to run the command manually on the command line, same results.

Is there a way to find out or fix why the verifier is unable to verify?

I’m seeing this issue as well in my plugin, but as far as I can tell, my zip file doesn’t contain any “special characters.”

Can be reproduced by checking out that repo and running ./gradlew :verifyPlugin.

This looks like an issue with IntelliJ Platform Gradle Plugin, even the most recent one.

However, please upgrade to the most recent version of the IntelliJ Platform Gradle Plugin, as your version is quite old now.
