uima-as build broken due to missing uimaj 2.4.0 artifacts in maven central

The UIMA SDK release generates an assembly binary distribution zip file. The release should have pushed this to maven central - allowing the uima-as build to download this artifact and unzip it, to enable binary uima-as builds to include base UIMA.

However, the last UIMA release failed to upload these to Maven Central. Ask on infrastructure for help in uploading these missing artifacts.
