I am not really sure what I should look into to fix it.

This looks like a mismatch between the API version that the plugin was built against, and the API version of the Gerrit server.
java.lang.NoClassDefFoundError: com/google/gerrit/extensions/events/GitReferenceUpdatedListener$Update
The GitReferenceUpdatedListener.Update class was removed from the API in Gerrit version 2.8.
To fix this you should first check which version of Gerrit your server is running, and then make sure you've built the plugin against the API with the corresponding version.

I followed the instruction and ended up compiling the plugin with both changes submitted in here: https://github.com/vadims/gerrit-owners/issues/6 (look for the 2 forked repo) and it did work.
It was painful but the plugin does an awesome job so worth the effort!

Unsupported major.minor version 52.0 - grails

I just downloaded a grails project from svn.
I saw that the unsupported major.minor version is a well known problem on S.O. caused by a mismatch version of JDK used during runtime and compile time.
But I am using the very same version as below:

Installed JRE:
Please what am I missing for still having the below error?

Compilation error: java.lang.UnsupportedClassVersionError: com/sun/tools/javac/Main : Unsupported major.minor version 52.0
I run it via rightclick on project -> run-as -> grailsCommand (run-app)

The project was compiled using a newer version of JDK but is being run at an older version. Clean all your code and rebuild the project.
Sometimes this is due to a plugin whose binary has been compiled with a higher version of Java.

I fixed it by using the appropriate groovy version for grails version I have.
You can find the link here.
For instance, grails 2.3.9 -> groovy 2.1.9
I also made sure to use the right Java version based on grails.project.target.level in BuildConfig.groovy. For me, it is 1.7 (java 7)

NoClassDefFoundError while setting up cucumber tests

I am getting the following error with my cucumber setup. I was following a youtube video (https://www.youtube.com/watch?v=pD4B839qfos&list=PL_noPv5wmuO_t6yYbPfjwhJFOOcio89tI) for this setup but I downloaded all the latest jars. Not sure what went wrong but now I can't figure out what needs to be done. Can anyone help me, please?

This means that Gherkin version you are using is not compatible with other Cucumber libraries. I tried using the latest gherkin3-3.0.0 but it did not work for me, so I degraded it to gherkin-2.12.2
I got below versions on Oct’17 for Cucumber
cobertura-2.1.1
cucumber-core-1.2.5
cucumber-java-1.2.5
cucumber-junit-1.2.5 cucumber-jvm-deps-1.0.5
cucumber-reporting-3.10.0 gherkin-2.12.2 junit-4.12
mockito-all-2.0.2-beta
The compatible version with your Cucumber-java can be found here under the Provided Dependencies section
If this does not resolve your issue make sure you remove jars from Project Build Path and add back again. Same if you are using maven then clearing local maven repository may also help.
You can also follow the steps mention in this tutorial

Never seen this before. What can I do to fix it? I already installed IntelliJ from scratch.

There was a file in /Library/Java/Extensions called netty.jar. I deleted it and the problem disappeared.

Qt for Android on OpenSuse 13.2

I've just upgraded from Opensuse 13.1 to 13.2 and can no longer get my Qt development for android to work correctly. My investigation leads me to believe that it's more of an android development issue (ant) than anything to do with Qt.
I'm getting the error below while trying to deploy the example projects. I've found that it might be tied to missing xml-apis package, possible the xml-commons packages should provide this functionality but they don't seem to.
I'm not at all familiar with Java and have been stuck on this for a while now. Any suggestions appreciated.

I solved the same problem by removing 'xml-commons', 'xml-commons-jaxp-1.3-apis' using opensuse 13.2 software manager and installing 'xerces-j2', 'xerces-j2-xml-apis', 'xerces-j2-xml-resolver' and my project reports BUILD SUCCESSFUL.
Complete steps for clarifying:
open "Software Management" from "Yast2" control centre.
search for "xml-commons".
Uncheck 'xml-commons', 'xml-commons-jaxp-1.X-apis' if are
checked(installed)[note: X stands for any version number], and
Accept for complete uninstalling that softwares.
Now search for 'xerces-j2'.
Check(install) 'xerces-j2', 'xerces-j2-xml-apis',
'xerces-j2-xml-resolver' from result list and Accept for installing
them or if they are currently checked dont tuch them!
that was all of my solution for this problem.
