What could possibly go wrong?

In JNLP: <j2se version="1.7"/> User: Java 1.8

What could possibly go wrong?

● Different Java versions installed on client machines● Sometimes javaws wants download and install latest JRE

version● Different behavior depending on Operating System and

installed JRE version● From some point of time apps needs to signed (Self-signed

are blocked)● Application started in sandbox (javaws or jp2launcher)

Profits

● We know a target JVM version● Application start outside a sandbox (java instead of

javaws)● We sign only IceBoar jar● Users don’t need admin rights to install JRE

Continuous Delivery

Release artifact to Maven Central is not so easy

● Hard to sign in / create account (need to find link and create an issue)● Manual verification of uploaded artifact

Release artifact to Maven Central is not so easy

Complicated Requirements:● Supply Javadoc and Sources● Sign Files with GPG/PGP● Sufficient Metadata (pom file)● Correct Coordinates (groupId, artifactId, version)● Project Name, Description and URL● License Information● Developer Information● SCM Information

Release artifact to bintray

● Sign in with GitHub● Add new package to maven repository, configure it● Deploy to bintray (from Travis-CI)● You don’t need to sign your artifact

Bintray general repository settings

Bintray deploy to Maven Central

● You can’t store user token password :-( ● This will be manual step :-(
