Description Ayah ElMaghraby

2016-02-24 06:33:00 EST

Trying to install Xtext on indigo always fails with same error on mwe packages.
This is the error:

An error occurred while collecting items to be installed
session context was:(profile=epp.package.rcp, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Multiple problems occurred while downloading.

It seems to be related to this bug  https://bugs.eclipse.org/bugs/show_bug.cgi?id=378155.
Although Xtext 2.8.1 seems to be working fine, this isn't the case anymore for 2.9.x.

I tried installing older versions of mwe/mwe2 (1.3.5 & 2.7.1) while installing Xtext 2.9.0 at the same time & un-checking contact all update sites but it doesn't work either because this time org.eclipse.emf.mwe2.launch.ui 2.7.0 cannot be read due to its signature.

Hi Ayah,,
I've checked the signing configuration for mwe builds and looks like they were signed using java8 signer.

I will fix that as soon as our build server is running again.

2.7.x was signed with java6 service. Java8 signing was introduced later in eclipse infrastructure. Unfortunately I can't check the signature because I have no java 6 installed on my mac.

Could you please verify, that the org.eclipse.emf.mwe2.launch.ui 2.7.0 fails to verify?

jarsigner -verify /path/to/the/org.eclipse.emf.mwe2.launch.ui_2.7.0_jar

A new 2.8.3 nightly build is under:

http://download.eclipse.org/modeling/emft/mwe/updates/nightly/maintenance

Please try it out.

Comment 4 Ayah ElMaghraby

2016-03-01 04:39:11 EST

I tried the maintenance build & i was able to install mwe. 
Will this fix be available for the new release of 2.11 ?

Comment 5 Dennis Huebner

2016-03-01 05:05:45 EST

It will be definitely fixed in current head stream mwe 2.9.0 (Neon M6 Milestone-build 22.03.2016)

For the maintenance stream, we will try to get a 2.8.4 Service release for MWE.
Stay tuned.

2016-03-01 05:26:41 EST

Thanks,
Please notify me when its available in the head stream.

As an additional info. Cause seems to be java.security.NoSuchAlgorithmException.

Unfortunately we can not use the SHA1 property for Neon [1] [2]

There is nothing I can do on our side.

Problem can still be reproduced. What I have done:
- Download Eclipse Classic Indigo 3.7.2
- Add update site Orbit Neon. Required to satisfy dependency on org.junit.internal 4.10
  http://download.eclipse.org/tools/orbit/downloads/drops/R20160520211859/repository/
- Configure Xtext Release Update Site
  http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/
- Install Xtext SDK, MWE 2 language SDK, MWE SDK

What I have also tried without success:
- use Xtext Nightly Update Site
- delete artifacts.xml, see http://stackoverflow.com/a/25095673/512227
- use JVM 1.7.0_79 instead of 1.8.0_92

I do not see a chance that we will be working on this. Xtext has Luna as last supported target and we can't support back to Indigo.
