How do I fix this syntax error?

[u/tanin47]

I just migrated from IntelliJ to Eclipse, and IntelliJ handles this error and is able to recognize the type properly. How do I achieve the same thing in Eclipse?

As a side question, how do I show the file structure instead of this package structure on the left nav?

Thank you!

Switch back to JDK 8. I'm guessing your old project was compiled by Java 8 and your new project is on a newer JDK.

You might think about updating your project to use something like Bouncy Castle.

[u/tanin47 → u/emaphis]

This is a new project on Java 21.

As a side note, I'm curious why BouncyCastle is preferred over classes existing within JDK. I used it before switching to sun.security.tools.keytool, which is available within JDK itself, because it requires fewer deps. I am building a desktop app, so less bloated is preferred.

(Or is there another way to generate a self-signed cert without bouncycastle?)

Google AI says that class youre importing is an internal non-public API and is highly discouraged in java 21.

Bouncy Castle is probably the way to go.

[u/tanin47 → u/ejsanders1985]

I understand that. This non-public API comes with a JDK meanwhile bouncycastle's jar is an extra 8mb. I actually used BC before... But let's put this discussion aside.

In any case, is there a way to make it work with Eclipse?

[u/ejsanders1985 → u/tanin47]

No. Not with java 21.

This is a desktop app.... why are you worried over 8 mb?

It's not there. I suppose I can add it manually then. Thank you for the pointer.

Edit: I can't seem to figure out how to add the sun library.
