The update script in this repository collects a list of currently available JRE/JDK distributions and their metadata to store it as JSON files in the metadata/ directory in this repository.

Additionally the script stores MD5, SHA-1, SHA-256, and SHA-512 checksums of the artifacts which are compatible with md5sum, sha1sum, sha256sum, and sha512sum in the checksums/ directory in this repository.

Supported OpenJDK distributions:

• AdoptOpenJDK
• Corretto
• Dragonwell
• Eclipse Temurin
• GraalVM Community Edition
• IBM Semeru
• Java SE Reference Implementations
• Liberica
• Mandrel
• Microsoft OpenJDK
• OpenJDK
• Oracle JDK
• Oracle GraalVM
• SapMachine
• Tencent Kona
• Trava OpenJDK
• Zulu Community

You can fetch the latest metadata for all releases at the following URL:

https://joschi.github.io/java-metadata/metadata/all.json 

Example with cURL (requesting a compressed version which significantly reduces the transfer size):

curl --compressed -O https://joschi.github.io/java-metadata/metadata/all.json 

If you want to fetch the checksum manifests for a JRE or JDK artifact, you can download it with the following URL template:

https://joschi.github.io/java-metadata/checksums/{vendor}/{artifact_filename}.{hash_function} 

• vendor: The vendor of the artifact, for example zulu
• artifact_filename: The original filename of the artifact, for example zulu11.37.17-ca-jre11.0.6-linux_x64.tar.gz
• hash_algorithm: The hash function you want to use; valid values are md5, sha1, sha256, and sha512

Example with cURL and SHA-256 checksum:

# Download Zulu Community™ JRE 11.37.17 for Linux (x64) curl -O https://static.azul.com/zulu/bin/zulu11.37.17-ca-jre11.0.6-linux_x64.tar.gz # Download SHA-256 checksum manifest for Zulu Community™ JRE 11.37.17 for Linux (x64) curl -O https://joschi.github.io/java-metadata/checksums/zulu/zulu11.37.17-ca-jre11.0.6-linux_x64.tar.gz.sha256 # Verify checksum sha256sum -c zulu11.37.17-ca-jre11.0.6-linux_x64.tar.gz.sha256
