are there other possible ways to use groovy in Eclipse except plugin - windows

I am using eclipse Mars 4.5.0 IDE and I would like to do some Groovy project.Adding groovy as a plugin is not working, because I am not able to connect to http://dist.springsource.org/snapshot/GRECLIPSE/e4.5/p2.index. In fact even simple update are not working. There is always some connection time out like connection to http://download.eclipse.org/eclipse/update/4.5/content.xml.
However I do have groovy installed on my system. Is there anyway I could tell the IDE to use the system groovy? Or is it possible to download the plugin and manually add it to the IDE? I am using windows 7

The groovy compiler delivered by the plugin is patched and therefore I don't think it is possible to use an external groovy compiler.
If you're behind a proxy, try to configure eclipse with manual proxy settings.
At least the 4.6 and 4.7 snapshot update site works well for me ATM, but when i had access problems, I downloaded the last working build from the ci server mentioned in the wiki:
e.g. E45 build and publish -> #393 -> Artifacts -> Zipped Update Site
and used it as an update site (add.. -> archive).

OSGI plugin development with Domino Designer 10

Up to date I was using IBM Domino Designer V9.0.1 FP8 to develop an OSGI plugin. With this version everything was working as intended. I've created a plugin project, a feature project and an update site project. Selecting "Build all" in the update site project created all the the corresponding jar files.
Today I've installed IBM (HCL) Domino Desinger V10 FP2 (fresh install i.e. I've deinstalled V9.0.1 and deleted the old "workspace" directory in NotesData, but I kept the NotesData itself).
Now if I open my plugin projects, I can edit the plugin, save the Java classes without any errors. Up to this point everything is working as usual. But now, if I use "Build all" in the update site project I see a screen with "generating ant script" and then the build process is finished, but no jar files are generated.
Any ideas why this is happening? Am I missing some files? Am I missing some configurations?
BTW: if I use standard eclipse to build the plugin all jar files are generated.
Domino Designer is a customised version of Eclipse. 9.0.1 FP9 and lower is a very old version of Eclipse, 9.0.1 FP10+ is a much newer version, so not comparable to what was happening before. It's possible there are differences in the customisation of Eclipse that are affecting it. But every Domino OSGi plugin developer I'm aware of uses standard Eclipse.
Follow the steps for setting up your environment here https://github.com/OpenNTF/XPagesExtensionLibrary/wiki/Development-Environment. In the documentation there I've tried to document why steps are done and what they achieve, as well as just the steps themselves. The intention is to pass on understanding to a broader set of developers, for future proofing.

jenkins enable maven command line

I want to setup jenkins using the command-line only. I am successfully able to install plugins and configure jobs. So i've installed the maven-plugin using jenkins-cli but want to be able to configure it to say "Automatically install maven latest version" so that when the user triggers a build it will automatically go download maven and then use it just like it does using the GUI.
Any advice on how i can do this piece of configuration on the command-line (or scripted ideally) please?
This option is not and should never be available for the reason that it destroys the concept of reproducible builds.
Changing the maven version deliberately may break the build at some future time for no apparent reason and will definitely startle your users then.
Please avoid this situation.
Why not use maven wrapper instead, this way each project configures specifically which version of maven it needs and automatically downloads it.

How can I debug a GWT project in Netbeans

I am developing a GWT project with Netbeans. When I debug it I always get the screen saying "Development Mode requires the GWT Developer Plugin". The problem is that my version of firefox is too recent to run that plugin. So what can I do?
Update to GWT 2.7, DevMode no longer requires a browser plugin (uses so-called "super dev mode" instead; where you debug in the browser rather than the IDE)
There's documentation for using the GWT Hosted Mode debugging in Netbeans, but you should be better able to use the newer GWT Super Dev Mode. To be able to set breakpoints in Netbeans though, you'd need to properly configure the source map support in Netbeans to map between the compiled JavaScript and the source Java files. I wasn't able to find an obvious reference for doing that with Netbeans.
The fun thing was that gwtproject.org made the sourcemaps part of the released site, and there was a tutorial to using them against their site to step you through how to setup your IDE... But again I didn't find that for Netbeans... Here's an example java source that's linked from gwtproject.org's JavaScript sourcemaps:

Is there a reason to install Gradle instead of using gradlew?

The recommended way to use Gradle is through the Gradle Wrapper, (gradlew), which is checked into version control of the project.
My question is: is there any reason to install Gradle myself from http://www.gradle.org/downloads instead of using the wrapper everywhere? (and copying the wrapper to new projects from an older project)
If You work with gradle occasionally (not with one particular project (or a set of projects)) it's very useful to have gradle installed on command line. Then You can easily create a script and check if it works fine. With gradle installed on CL it's very easy and fast (no need to download the whole distribution every time). Beside this one particular use case nothing else comes to my head.
P.S. There's a great tool for gradle (and other tools) version management: GVM.

Jenkins RequireJs Build / CI

I've just started a project that uses RequireJs, Backbone etc. Everything is running well client-side and I wan't to set up my build environment.
I was planning on using Jenkins but have found zero information on how to go about this. I've managed to set up Gradle and use that to do things like minify the js etc, but I think I need to run R.js and have no idea where to get started or if this is even what I should be doing.
I've googled a bunch and found nothing. Sorry for my ignorance.
Jenkins has a Gradle plugin: Gradle Jenkins Plugin
Installation
The plugin is very easy to install and use. To install it, just use the Jenkins web interface.
Manage Jenkins -> Manage Plugins -> Available Plugins -> Install
Search for Gradle, check the box and click install.
Create a job
Click new job. Select free style job and add a Gradle build step.
