Need reliable way to download uima binary artifact from standard Apache spot
----------------------------------------------------------------------------
Key: UIMA-2369
URL: https://issues.apache.org/jira/browse/UIMA-2369
Project: UIMA
Issue Type: Bug
Components: Build, Packaging and Test
Reporter: Marshall Schor
Assignee: Marshall Schor
The uima-as build is somewhat broken. A fix was made to download the base
uimaj sdk binary build (upon which the uima-as build depends) by adding a new
goal to the uima-build-helper-maven-plugin. That goal has a small bug - it
doesn't create the intermediate directories needed when creating the output
file for the download.
However, it has a bigger problem - the download runs a small loop, reading from
the URL open stream, and writing to the local file. The loop ends when the
read method returns -1 for the number of bytes read. Java is supposed to only
return this when the end-of-file is reached, but (randomly) it is getting
returned early. This results in a corrupt download, with only the first part
of the file being downloaded.
Investigate and fix.
