java.io.IOException: Invalid Keystore format
You may corrupt the file during copy/transfer.
Are you using maven? If you are copying keystore file with "filter=true", you may corrupt the file.
Please check the file size.
Maybe maven encoding you KeyStore, you can set filtering=false to fix this problem.
