Agree something is weird, as Java is normally supported out of the box

We even have a Java snipped in ur website:
https://docusaurus.io/docs/next/markdown-features/code-blocks#multi-language-support-code-blocks

Is this a new bug after upgrading to alpha 75? Was it working before?

[stockiNail]

@slorber I was using alpha-68 and it worked!

We even have a Java snipped in ur website:
https://docusaurus.io/docs/next/markdown-features/code-blocks#multi-language-support-code-blocks

yes, sounds working on the official doc, but not in code sandbox (and in my project).. :(

[slorber]

Can you try alpha 74? Alpha 75 is a big upgrade (Webpack 5) so it is more likely to have a few issues

[stockiNail]

npm i @docusaurus/[email protected] @docusaurus/[email protected]

Nothing is changed. Furthercode, in sandbox, the Docusaurus version is alpha.73

[stockiNail]

I have created new sample project, by npx @docusaurus/[email protected] init my-website classic and added the java code.

Same error, JAVA code is not highlighted.

There's the same issue here #4535

According to the docusaurus doc,

By default, Docusaurus comes with this subset of commonly used languages.

Which doesn't include Java, PHP, or Ruby. You have to manually include them in the config.

@Josh-Cena GREAT!!! Thank you! I don't know why I was convinced to see the code highlighting in version alpha.68...

[Josh-Cena]

Yeah, don't know when they stopped supporting Java—probably when they started using Prism? I also remember using Java back in ~alpha.68

[slorber]

This is still weird for me: the Docusaurus site itself does not add any additional config and is able to highlight that Java code block here:

https://docusaurus.io/docs/next/markdown-features/code-blocks#multi-language-support-code-blocks

But nevermind, indeed Java should be added to the list of additional languages as it's not in the default enabled languages of react-prism-renderer

[stockiNail]

I agree, it's very weird...
