Hmm, not sure what happened, replaced with 1.47.2 or 1.46.1 same problem. It was working fine

What's your version of "Debugger for Java" extension? Could you try to downgrade it to 0.26.0 to see whether it still happens?

Mike-the-one commented 4 years ago

@testforstephen Thanks!!! it works in 0.26.0... did not realize that debugger for java was recently updated, otherwise I would have downgraded it first :-) wasted me a couple hours downgrading VSCode, clean install etc :)

@Mike-the-one Would you mind sharing a sample project and some steps to reproduce the issue? A minimum project that can reproduce the issue would be helpful to find the root cause?

Palidino commented 4 years ago

I'm also having this issue, but I don't have a sample project for reproduction of the bug. All I know is that since the update, it doesn't work for either project I work on. It just says there are no changes. Like OP, with Java 8 and 11.

testforstephen commented 4 years ago

i reproduced it. Actually HCR succeeds, just report a wrong status about no changes found. Will push a hotfix for it.

testforstephen commented 4 years ago

The latest 0.27.1 already has the fix.

Mike-the-one commented 4 years ago

@testforstephen Thanks for fixing this!

Palidino commented 4 years ago

I'm on 0.27.1 and still get told: "cannot find any changed classes for hot replace!"
