Retreive Metabase version from .jar

Hello,

I am wondering if it is possible to retrieve the Metabase version from the .jar file. I would like to develop a utility to automatically update Metabase.

a JAR file is a compressed file, open it with a compression tool and you'll find a version file in there

Please post what's your current approach so we can help you

Thanks for the tip! I came up with this PHP function:

function extractMetabaseVersion($path){
	if (file_exists($path)) {
		$zip = new ZipArchive();
		if ($zip->open($path) === true) {
			for ($i = 0; $i < $zip->numFiles; $i++) {
				$fileName = $zip->getNameIndex($i);
				if($fileName == 'version.properties'){
					$fileContents = $zip->getFromIndex($i);
					$keyValues = explode("\n", $fileContents);
					$parts = explode("=", $keyValues[0]);
					$result = preg_replace("/[^0-9.]/", "", $parts[1]);
					return $result ;
				}
			}
			$zip->close();
		} else {
			echo "Failed to open the JAR file as a zip archive.";
		}
	} else {
		echo "The JAR file does not exist.";
	}
}

Why don’t you simply hit the properties endpoint where the version is located?
