Detect Java in any GitHub repo

Java is one of the language technologies Stack Fingerprint recognises automatically when it scans a public repository.

How Java is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags Java when it finds any of these:

  • Files or folders: /^build\.gradle(\.kts)?$/, /\.java$/, pom.xml
  • File extensions: .java

Java README badge

A static badge you can paste anywhere in Markdown:

Java badge

Markdown
![Java](https://img.shields.io/badge/Java-ED8B00?style=for-the-badge&logo=openjdk&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so Java (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
