Indeed, in recent releases we gave up distributing the third-party jars in the lib folder and instead, we are using the Apache Ivy plugin for Ant to automatically download them from public Maven repositories at source code build time or when running the samples.
So you need to download them on your own from public repositories. In the next release, there will be an Ant target to retrieve them all with a simple command.
Until then, copy this snippet in the build.xml file found in the root folder of your JR 6.2.2 source distro:
<target name="retrievelibs" description="Retrieve dependencies with Apache Ivy">
<ivy:retrieve conf="compile, javaflow, test" pattern="dist/lib/[artifact](-[classifier])-[revision].[ext]"/>
</target>
If you launch >ant retrievelibs
from command line, you'll have all libs required to compile JR Lib places in the /dist/lib folder of the project.
Note that depending on which are of functionality you use, you'll need additional JARs. Each sample in our project distro brings additional JARs needed at runtime. You can check which JARs are needed as they are listed in the ivy.xml file of that particular sample. You can use a similar target in the build.xml of the sample to have those JARs downloaded for you.
If you are using Maven, you could launch:
>mvn dependency:copy-dependencies
command and get all dependencies including the transient ones in the target/dependecy folder of the JR project.
