When using the Ext JS "binaries" in Jangaroo's build process, it should be available as a Maven artifact like everything else. There are several branches in this repository for the different Ext JS versions. Unfortunately, we may only publish the GPL version of Ext JS to Maven Central, so the branch ext-js-6.2-gpl is probably the most interesting one.
For commercial versions, please contact your OEM vendor (most likely CoreMedia) or use the POM from the corresponding branch in this repository to build and privately deploy the desired Ext JS version's Maven artifact.
For examples of how to use the published GPL Ext JS Maven artifact, see Jangaroo Ext AS Examples.
