Looks like the manifest or signature file digest is an issue:

% jarsigner -verify swtmac_aarch64-4.31.jar
jarsigner: java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

% jarsigner -verify swtmac_aarch64-4.30.jar
jar is unsigned.

This issue occurs for v4.31 Windows and Linux jars too.

I am having the same problem when attempting to use SWT 4.31's swt.jar from JRuby on Mac (Intel).

SecurityError: Invalid signature file digest for Manifest main attributes
       java_import at org/jruby/javasupport/ext/Module.java:91

I am using macOS Ventura 13.4.1 on Intel Core i7 (x86_64 aka x64), JDK22, JRuby 9.4.6.0, and SWT 4.31 for Mac x64 (aka x86_64).

I am wondering 2 things:

- This annoying error which we have no fix for is there even in the SWT release 4.32. It seems they keep releasing unusable releases. Why did this bug make it into 2 releases in a row, and why has this bug not been fixed in the many months that have passed?
- Why did nobody else reply in this thread? Is the community so small that no one else cares? Nobody else is using SWT 4.31 or 4.32? Just the three of us? Does this mean Eclipse/SWT is hopelessly abandoned at this point? I should switch to something else?

Thanks for reading.

I have the same problem using Raspberry/Linux.
I am an extensive User of swt Technology since many years. I would like to migrate my swt Applications from Eclipse 2022-06 to Eclipse 2024-06

A workaround for the issue is to remove the following files from jar:
META-INF/ECLIPSE_.SF, META-INF/ECLIPSE_.DSA, META-INF/ECLIPSE_.RSA.

This can be done using "zip -d" or similar command.
