Builders page disappeared from Eclipse project properties - eclipse

I do not know what happened to my Eclipse (Helios) with latest Android SDK and latest Sequoyah plugins. Suddenly, I do not see my the "Builders" page in Project properties - not for a single project in my workspace.
How can I restore this page?

Check which perspective you are in at the moment (upper right corner). A perspective can suppress UI contributions (such as property pages). It is possible that one of the plugins you've installed comes with its own perspective that does that. Try switching to Resource or Java perspective.

Eclipse feature and plugin not visible after installing from updatesite

I made several new E4-based plugins, each defined in a fragment.e4xmi file. The simplest one should just show a test menu in the main menu and a test popup menu.
When running an Eclipse instance from the development IDE, everything works as expected. However, when publishing those plugins and features via a test update site, an end user can install the new plugins using the update site, but the UI is not visible in the Eclipse IDE. In the Help / About Eclipse IDE / Installation Details, the "Installed Software" shows my new plugins, but the features list does not. The Plug-Ins list does show some utility plugins, but none of those contributing to the UI.
Older plugins (not using e4) are visible as expected.
Which settings do I have to check?
How can I debug the installation?
Thanks in advance.

PyDev cause duplicated show of project in Eclipse J2EE perspecitve

I just installed the latest PyDev 4.4.0 plugin to my Eclipse Mars.1. I created a new Java project in a new workspace. And I add the project to a workingset. In the Eclipse JavaEE perspective, the project has duplicated show in the Project Explorer view when I show workingset as the top level element:
I uninstalled PyDev, now the project show is OK.
Anyone knows the root cause? Or a workaround?
Ref:
A possibly related link: Projects appearing twice in working sets - eclipse
A related Eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=373031
A related J2EE tooling bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=351764
Well, given that the original report on J2EE is still open: https://bugs.eclipse.org/bugs/show_bug.cgi?id=351764 I don't think this can be fixed at the PyDev side (although it makes the problem appear, it should be fixed on the J2EE side).
As a note, if anyone wants to take a look, on the PyDev side, this happens at: https://github.com/fabioz/Pydev/blob/development/plugins/org.python.pydev/src_navigator/org/python/pydev/navigator/PythonModelProvider.java, but it's done with the proper APIs (using IPipelinedTreeContentProvider), and I'm currently convinced the issue doesn't lie on the PyDev side (although if I'm proved wrong, I'd be happy to fix it).
A workaround would be disabling PyDev or J2EE (depending on which kind of content you use more) just at the explorer level (i.e.: in the explorer do Ctrl+F10, Customize View, Content, disable the PyDev Navigator Content or the Content related to J2EE).

Eclipse 4.4 Luna pinning editor tabs

I've found this question: Eclipse - How to pin editor tabs? and I've installed "Extended VS Presentation plugin for Eclipse", but it's not working.
How it should look (from http://andrei.gmxhome.de/skins/index.html):
How it actually looks on my Eclipse 4.4 (on Ubuntu):
As you can see, "Current presentation" setting is missing.
When I've installed this plugin (via eclipse), it was in "Eclipse 3.6 - 3.8 plugins", so maybe it's incompatible with 4.4 Luna? However, it was possible to install it, so it should work, right?
Also, if you know any plugin that would allow pinning tabs in eclipse, feel free to post your answer and describe it.
Support eclipse versions for this plugins:
Eclipse Versions:
Juno (4.2, 3.8), Previous to Juno (<=4.1)
This plugin NOT works(See this) in eclipse 3.x on Linux.(But here author says it support Linux platform. Contact author for more details)
This plugin NOT works in eclipse 4.x on any platform.
Please note, that the skin, tab actions and lists are available for Eclipse 3.x only! Eclipse 4.x is not supported.
That first Appearance dialog is how it looks in Eclipse 3.x. The appearance code was completely rewritten for Eclipse 4.x.
The fact the plugin installs may just mean the install is not careful enough about specifying the versions of Eclipse it supports.
You should try and contact the plugin author to see if it supports Eclipse Luna.
In my point of view, everything is fine.
As you can see in the images below, (Check bottom (console) ).
The above page is updated on 06-25-2014
But the screenshot in that page is taken on 06-02-2008 , (Check bottom (console) ).
The screenshot given in that page is a screenshot of very very old version. The plugin is updated, but the screenshot in the page is not yet updated.
The new plugin will work as shown in the image in the question
Alternative
In Eclipse 4.4.0 there You'll find a pin symbol in the default toolbar of Eclipse on the right side. After clicking it, the Java Editor Tab symbol gets changed indicating this editor is pinned now. Unfortunatelly I could not find a corresponding entry in the popup menu. But it is easy to assign e.g. the keys Ctrl-P to "Pin Editor" in the key bindings of Eclipse. (Don't forget to unbind Ctr-P = Print).
In Eclipse Neon 4.6.0 Pin is not functioning.

How to show short cut to android sdk and adt manager on eclipse

I have updated eclipse. But I have to always go to android sdk folder on my file system and navigate to tools located in that folder. In ealry versions, there were short cuts to adt and sdk tools on eclipse. They were shown under the menu bar of eclipse. Is there way to get them back again on to eclipse?
First, these should show up automatically under the "Java" perspective in Eclipse. You can show it using Window->Open Perspective->Java (or if Java does not appear there, use Other and select Java from the list).
If you want to add it to other perspectives (like the Java EE perspective)
Choose Window->Customize Perspective
Click on the Command Groups Availability tab
Check Android SDK and AVD Manager
Press Ok
You may also want to check Android Wizards to get the buttons for creating an Android XML file.

In Indigo with CCRC 7.1, The clearcase menu buttons on the Java EE perspective are disabled. How can I enable them?

In my eclipse Indigo installation, I have the clearcase remote client (CCRC) perspective working - it's connecting the server just fine and the functionality is there. However, in the Java EE perspective most of the buttons are disabled.
When I edited a file in the Java EE perspective, it used to ask (with a previous version of CCRC and eclipse ganymede) if I wanted to check it out. However, now it merely asks if I want to make the file writable (default eclipse behaviour).
Basically most of the CCRC functionality in the Java EE perspective is disabled. I can see the buttons in the toolbar, but they are disabled (greyed out). Clearcase is also not showing up in the right-click context menu under Team.
Thoughts?
All recent CCRC (7.1.x) settings I managed are build on the same premiss:
That the .project and .classpath are part of the snapshot 'web' view which is a CCRC view.
That is what indicates eclipse that this eclipse project is managed under source control.
CCRC has considerably changed its way of running since 7.1 (2009 as this release notes history illustrates)
Since those eclipse definition files should be under source control anyway, this shouldn't be an inconvenient.
VonC - great comment. That was the issue - we're creating our projects outside the clearcase view and importing the code into that project. However, the correct way to make the buttons functional is to create the project within the folder where the view is. That will enable the checkin/checkout functionality.
Whether or not that is a bug in CCRC is left up to the reader - the way we used to do it with previous CCRC versions worked fine, but that is not the same way it's working now.
