Can't connect to any repository - egit

I am using egit with Eclipse Java EE IDE for Web Developers. Version: Neon.3 Release (4.6.3) Build id: 20170314-1500. I am using the default connection settings. I have pushed multiple times but today my team and I faced the below error while pushing.
Can't connect to any repository:

I have changed the project name in the above. I am able to connect to the remote repository in the browser.

java ee app deploy to openshift gives 404 error

I have a Java EE app developed in eclipse and converted to maven. I've setup the rhc tools on my pc and pushed to git (including the webapps folder in my project with the project's war file). But when I try to access the site it says 404 - resource not available. How long does it take for openshift to update the git push commands from my pc? My Welcome file lists Startup.jsp as my start page. Should I rename this to index.jsp? What factors are there to consider?

Setting up Eclipse and Maven to build a simple Jersey Webapp

I had this working previously but had to reinstall everything because my hard drive died. I'm trying to build a simple jersey application via the archetype jersey-quickstart-webapp. The code is unchanged from the archetype so it's unlikely an issue with that as I had it working before the PC issue.
I'm fairly certain it's an install issue with Eclipse or Java or something else. My timeline of events goes as follows. I created the archetype project and got this error:
Plugin org.apache.maven.plugins:maven-war-plugin:2.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-war-plugin:jar:2.2: Could not transfer artifact org.apache.maven.plugins:maven-war-plugin:pom:2.2 from/to central (http://repo.maven.apache.org/maven2): connect timed out -> [Help 1]
From this I searched for solutions which included deleting the repository folder and everything in .m2, forcing the project to update dependencies etc.
While doing this I noted that the option to Run As-> Run On Server was not available as an option.
I went to manually add Project Facets > Dynamic Web Module, it said this requires Java 1.6 or newer. So I tried to lower the version all the way down to 2.2 which needs Java 1.3, none allowed me to check the box. I have Java 1.7 JDK installed.
This is where I stand. Can anyone please help!!?

How to connect from Mylyn to Redmine?

How to connect from Mylyn to Redmine?
Are there any connectors?
This site pretends to have one https://github.com/danmunn/redmine_mylyn_connector
but contains only instruction to install something on server side. How eclipse can know there is some server?
UPDATE
Plugin from here Mylyn & Redmine Integration is not working, saying "error 404".

Eclipse plugin to SonarQube 4.0 not finding provisioned project or creating new project

I am running the SonarQube plugin with m2e integration inside Eclipse Keplar. I am trying to run with a SonarQube 4.0 standalone server, running from the command-line on a win7 64 box.
When installing and reloading Eclipse the sonar plugin detected m2e and turned on the Sonar "nature" for me, including a project tag. The install also configured the SonarQube Eclipse properties to point to the localhost:9000 server. I can log in to the running server with chrome, and the Eclipse properties has a "test connection" option which passes. I am using empty user and password.
Problem 1: When I try and run SonarQube->Analyze on my project it completes and populates my project with issues. Great, except that this information is not pushed to the server and the start of the console log states:
Retrieve remote issues of project XXXXX...
Project not found on remote SonarQube server [com.company.xxxx:XXXX]
Start SonarQube analysis on XXXX...
INFO: SonarQube Server 4.0
I have tried to provision a project for com.company.xxxx:XXXX, and I have turned the security for provisioning off to act like SonarQube 3, but the project analysis does not get added to the server.
So the plugin can clearly contact the server. I have tried to add the admin credentials to the plugin to get past any permission issues. I have overridden the default maven-generated tag name to something else, and also added provisioning for the new name. I keep getting "Project not found" messages.
Am I missing something? The tutorial on the SonarQube tutorial makes it seem like this is correctly configured, but web searches are not coming up with similar experiences.
This appears to be a result of the Maven integration. Updates are only pushed to the server when running directly against the Maven repository. When running locally the analysis data is compared to the server data to find deltas, but the server data itself is not updated. This actually makes a lot of sense in a team environment, but was a surprise when the SonarQube tutorial calls out Maven integration but not this caveat.
After performing an analysis from the SonarQube server directly against the Maven repo (without Eclipse in the picture at all) the project was created and populated with the data. This data was then available in Eclipse and local analysis would delta against that data (although it would not update it, which also makes sense).

Deployment fails with 'An internal error occurred during: "Start Worklight Server"'

I have Worklight Developer 5.0.6 installed on Eclipse 4.2.2 (Juno).
Trying to deploy a plain-vanilla Worklight project (hybrid WL application created w/ Wizard), I get a pop-up window entitled Problem Occurred. The Details view shows this error message:
An internal error occurred during: "Start Worklight Server".
org/apache/tools/ant/types/selectors/FileSelector
The Worklight Console in Eclipse shows this:
[2013-05-28 09:51:58] Worklight Server started successfully on localhost:8080
[2013-05-28 09:51:58] Activating Worklight project: DemoAppProject...
[2013-05-28 09:51:58] Customization not found for project DemoAppProject.
Building explicitly.
Checking the Worklight Console on http://localhost:8080/console I see that the server is running, but there's no active project.
What am I missing?
#bluez,
Based on your comments to my questions below,
I've installed Eclipse Classic 4.2.2 (Juno, on my Mac OS X 10.8.3) and Worklight Studio plug-in from the IBM website you've linked to.Created a new Worklight project and application. Build all and Deploy - deployment passed successfully.
Make sure that:
The "check for updates" checkbox is ticked before starting the plug-in installation.
You have Java JDK version 6 or later installed
Is this Eclipse Java EE 4.2.2 (Juno SR2), or another variant?
Does the project's .war file exist under the project's bin\ folder?
Is this a clean installation of Eclipse and Worklight plug-in, or an upgrade?
Try suggestions (from both the questions and anwers) from this question: Worklight fails to install customization jar
