"zip file is empty" when installing RTC Eclipse plugin

Question

I'm trying to install the RTC-Client-p2Repo-4.0.5.zip (290.9 MB) eclipse plugin in Eclipse Luna version 32 bit on Linux. After selection the jar file and hitting finish, I get the error at the bottom. The jar file size is 290.9 MiB (305,030,442 bytes) and I am able to extract it.

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust, operand=, action=).
Error reading signed content.
zip file is empty

Answer 1

An RTC 4.x+ is meant to be installed in an Eclipse 3.6+ (as in "Install RTC Eclipse Client 4.0 into an existing Eclipse 3.6.2 using Installation Manager")

The support for a latest Eclipse 4.4 Luna is not guaranteed.

Answer 2

I re-installed eclipse and that fixed the issue. The ".eclipse" folder may need to be removed too, although I didn't see one in my Linux VM.

Answer 3

My solution was to go through Help-->Eclipse Marketplace, search for the plugin and install it from there.

Answer 4

Issue Identified & Solved This issue arises when u try to retrieve the codBase from RTC repository to your local Workspace. Usually u might be facing following issue :

1. Jar files in your project gets corrupted due to inevitable pushing of code in RTC repository as you would have been getting the following error where in my case Platform.jar was corrupted.

   WARNING: Failed to process JAR [jar:file:/D:/Workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ProjectName/WEB-INF/lib/platform.jar!/] for TLD files
   

Solution :

1. Try Replacing the corrupted jar files in your workspace at the respective location.
2. Try to push fresh/updated code in RTC repository,so the jar files wont get corrupted
