exception in thread "main" java.lang.securityException: invlid signature file digest for manifest main attributes
This error occurs when the JAR file being executed has an invalid signature in its manifest file. This can happen if the JAR file has been modified or tampered with after it was signed.
To fix this error, you can try the following steps:
1. Check if the JAR file has been modified or tampered with. If so, obtain a new, unmodified version of the JAR file.
2. If you have signed the JAR file yourself, make sure you have followed the correct steps for signing a JAR file.
3. If the JAR file was signed by a third-party, contact the vendor or developer to obtain a new, valid version of the JAR file.
4. If none of the above steps work, you may need to remove the invalid signature from the JAR file. This can be done using tools like "jarsigner" or "zip" command-line tools. However, this may not be a recommended solution as it can compromise the security of the application.
