These are sample files for a project. - lightpack/ is one modpack - monsterpack/ is another modpack - upload/ is what you'd upload to your website In upload: - "latest.json" was written by hand - "packages.php" automatically generates the package listing, but your web server needs PHP installed to use it - "packages.json" is what packages.php would have generated, but you can write it by hand instead - "news.html" is your news page Commands ======== The following commands were run to generate the modpack files in upload/ java -jar ../launcher-builder/build/libs/launcher-builder-4.2.3-SNAPSHOT-all.jar --version 20100223 --input lightpack --output upload --manifest-dest "upload\lightpack.json" --pretty-print java -jar ../launcher-builder/build/libs/launcher-builder-4.2.3-SNAPSHOT-all.jar --version 20100223 --input monsterpack --output upload --manifest-dest "upload\monsterpack.json" --pretty-print launcher.properties =================== If you had uploaded the contents of upload/ to http://example.com/launcher/, you would make launcher.properties look like this: newsUrl=http://example.com/launcher/news.html?version=%s packageListUrl=http://example.com/launcher/packages.php?key=%s selfUpdateUrl=http://example.com/launcher/latest.json (note: it uses the .php version here)
