Bug ID: 1523102 Summary: google-guice 4.1-8 breaks Xtext Product: Fedora Version: 27 Component: google-guice Assignee: mizdebsk@redhat.com Reporter: ugilio@gmail.com QA Contact: extras-qa@fedoraproject.org CC: java-sig-commits@lists.fedoraproject.org, mizdebsk@redhat.com, msimacek@redhat.com, sochotni@redhat.com
Created attachment 1364112 --> https://bugzilla.redhat.com/attachment.cgi?id=1364112&action=edit The stack trace in the Eclipse console
Description of problem: After the update from 4.1-7 to 4.1-8, recent Xtext versions (tried with 2.12.0 and 2.13.0) don't work anymore (java.lang.NoClassDefFoundError: net/sf/cglib/core/CodeGenerationException). Tested on both fedora 26 and 27. (Sorry for not having reported it earlier, I thought the problem was on my side, I was in a hurry and I simply downgraded guice to 4.1-7...)
Version-Release number of selected component (if applicable): 4.1-8
How reproducible: Always
Steps to Reproduce: 1. Start eclipse 2. Install Xtext complete SDK from update site: http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/ 3. After restarting Eclipse, create a New Xtext Project and accept all defaults 4. In the newly-generated MyDsl.xtext right click and select "Generate Xtext Artifacts"
Actual results: No artifact is generated. In the console:
[main] ERROR mf.mwe2.launch.runtime.Mwe2Launcher - com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: net/sf/cglib/core/CodeGenerationException ...
Expected results: No error occurs, the artifacts are generated.
Additional info: - I'm using default java-1.8.0-openjdk-1.8.0.151-1.b12.fc27.x86_64 - google-guice 4.1-7 works fine

--- Comment #1 from Mikolaj Izdebski mizdebsk@redhat.com --- google-guice 4.1-8 started to import cglib, but with resolution:=optional eclipse-m2e-core seems to be the only packaged plugin using guice (based on: dnf repoquery -al | grep droplets | grep guice), but it doesn't link cglib Mat, what is your opinion on this?
Giulio, can you check if installing eclipse-recommenders fixes the issue?

--- Comment #2 from Mikolaj Izdebski mizdebsk@redhat.com --- Adding correct CC this time. Mat, what is your recommendation on the fix?
https://bugzilla.redhat.com/show_bug.cgi?id=1523102
--- Comment #3 from Mikolaj Izdebski mizdebsk@redhat.com --- If I understand this correctly: - our guice has cglib unbundled and replaced by optional import on cglib - m2e uses guice, but doesn't symlink gclib - deps of 3rd party plugins that use guice will be satisfied by our guice bundle - it works for them because they normally bundle cglib - but cglib is not available in our installation, resulting in NoClassDefFoundError
possible solutions: - change import to non-optional - add BR on cglib to m2e, so that symlink is generated by fp-p2

Giulio, can you check if installing eclipse-recommenders fixes the issue?
Actually I had eclipse-recommenders installed. Removing it though fixed the problem. I always thought google-guice was the problem, but actually when downgrading guice to 4.1-7 I also had to downgrade eclipse-recommenders to the previous version, but I never tried to remove it.

--- Comment #5 from Giulio Bernardi ugilio@gmail.com --- After updating to Oxygen.2 (eclipse-platform-4.7.2-0.2.fc27.x86_64) the problem is the same.
- If I install eclipse-recommenders-2.4.10-3.fc27.noarch, I got the error I originally mentioned - If I remove it, everything works
I test every time with a new eclipse configuration directory and workspace.

--- Comment #6 from Ben Cotton bcotton@redhat.com --- This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
