M1 can't open jar file (jar is damaged)

[cobapple]

Hi guys, I've many jar files (java applications) that can't be run on Macbook Air M1. Everytime I open it, it says the file is damaged an can't be opened (see screenshot below).

How do I solve this?

Thanks in advance

I guess it is being quarantined by macOS gatekeeper. In terminal try to run xattr -d com.apple.quarantine file.jar

Try right-click open to see, whether it lets you override. Needless to say, Java must be installed.

Look at the message, it’s trying to extract it (since a JAR is essentially a zip file) not run it.

Have you installed a JDK to actually run it? JDK doesn’t come with it by default.

I thought OpenJDK for M1 is still in beta? I know it is based on the Windows ARM64 OpenJDK, which merged into mainline last year.

No, most of the JDKs of 8 and up are available. They don't say beta anyway. I have a couple installed via brew and a few downloaded from Azul.

Are you sure we are talking about native ARM64 versions? Of course i guess you can just run the x64 version under emulation just fine.

Yes. These are are all native Aarch64. Some of the brew versions aren’t though. You have to check.

Azul is native, indeed. Download here.
Use Firefox, Safari has trouble with Azul's version selector routine checking platform specs.

If it can't open the jar, call the husband to help
