Summary

Hi all,
I would like to install a new (SAP) ABAP Plugin in Eclipse (Ex. ABAP Favorites) by "local" mode . But Unfortunatelly I can't because a blocking error !
(I do it by local mode ; otherwise i have proxy error on my customer office)

Steps to reproduce

•   (menu) Help / Install new software
  

• (popup "install") button "ADD"
• (popup "add repository") button "Archive"
• select the zip downloaded in github
• @ location = jar:file:/C:/Users/XXXXX/Downloads/ABAPFavorites-master.zip!/
• clic on "Add"
• @@@ direct error message : could not find jar:file:/C:/Users/XXXXX/Downloads/ABAPFavorites-master.zip!/
• if I try on : location = jar:file://C:/Users/XXXXX/Downloads/ABAPFavorites-master.zip!/
• clic on "Add"
• @@@ error : Unable to read repository at jar:file://C:/Users/XXXXX/Downloads/ABAPFavorites-master.zip!/content.xml.

Any idea on how to solve my problem please ?
Thks,
