The default filetransfer provider may be changed from httpclient45 to the older httpclient4 provider by setting the following system property upon eclipse (or other app) startup:

org.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45

For example, to set this property when starting Eclipse:

eclipse -vmargs -Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45

This will disable the Apache HttpClient45 provider, and force using the apache httpclient 4 provider.

To disable both the httpclient45 and httpclient4 provider and used the JRE URLConnection provider:

org.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45,org.eclipse.ecf.provider.filetransfer.httpclient4


In some proxy environments this will allow the downloads to succeed by using the URLConnection provider rather than the HttpClient4 provider.
