Eclipse 2022-06 does not contain Mylyn anymore which is required by the Vaadin plugin.
As solution, in the preferences Install/Update > Available Software Sites, add the update site https://download.eclipse.org/mylyn/releases/latest before installing the Vaadin plugin.

AEM plugin is not available in eclipse marketplace

I am trying to add AEM plugin in eclipse but it is not available in eclipse marketplace
Current eclipse version - Version: 2022-12 (4.26.0). I want to install the AEM plugin in eclipse but I am not sure why it is not working in the current version. Is there anything else I need to add to make this work?
[UPDATE]
I get below error when manually trying to install using "Install New Software"
Cannot complete the install because one or more required items could not be found.
Software being installed: AEM Developer Tools 1.3.0 (com.adobe.granite.ide.feature.feature.group 1.3.0)

Yes, AEM Developer Tools is not listed in the Eclipse Marketplace. You might ask Adobe to do so.
But you can manually install AEM Developer Tools via the update site https://eclipse.adobe.com/, following the instructions here.
According to your update, the error when trying to install manually:
The required plugin/bundle org.eclipse.equinox.ds has been removed in the 2022-12 release. In the preferences Install/Update > Available Software Sites add the update site https://download.eclipse.org/releases/2022-09/ and try again. With this, installation of AEM Developer Tools 1.3 should work. If you run into problems running it, you might want to use Eclipse 2022-09 as a workaround until AEM Developer Tools has been adapted for Eclipse 2022-12.

Unable to install LDT to Eclipse 2019-12 (4.14.0)

I was setting up a new laptop and downloaded Eclipse: Version: 2019-12 (4.14.0) but when I tried to add the LDT plugins, it fails because it cannot satisfy dependency (see below.)
The prior version of eclipse I had on my last laptop was 2018-12 (4.10.)
Does anyone have a list of what or know which the last/latest version of Eclipse which works with the (1.4.2?) LDT plugin is?
[[EDIT]] => Verified that Lua Development Tools still installs if I reinstall 2018-12 Eclipse. So it is a compatability thing as I asked. Since no one yet has the answer, I will install one after another Eclipse version to determine last that works and update this entry. VERIFIED: 2019-09 is the latest that works with LDT plugin.
(pointed repo to "stable" (although tried even nightly after that)
Error message:

The key error here is
requires 'osgi.bundle; org.eclipse.dltk.core [5.5.0,6.0.0)'
which is saying that a version of the 'org.eclipse.dltk.core' plug-in (bundle in OSGi terminology) with a version of at least 5.5.0 and less than 6.0.0 is required.
The Eclipse 2019-12 release has version 6.0 of this plug-in so it does not match the criteria and the install fails.
I installed earlier versions of Eclipse IDE (Java) and it appears the version right before the one I was trying (2019-12) is the last that will accept installing the LDT plug-in successfully: Eclipse (Java) 2019-09
Hopefully it is a bug that gets fixed in either LDT or Eclipse 2019-12.
There is a workaround that I found here: https://www.eclipse.org/forums/index.php/t/1101907/
The solution is basically to provide the missing resource from a download since it doesn't seem to be available from repositories any more:
Download the runtime for DLTK 5.7.1 as a zip: http://www.eclipse.org/downloads/download.php?file=/technology/dltk/downloads/drops/R5.7/R-5.7.1-201703020501/dltk-core-R-5.7.1-201703020501.zip
In Eclipse, navigate to menu > Help > Install new software...
Click Manage... to go to Available Software Sites dialog
Click Add... use a good name like "LDTK zip", click the "Archive" button and browse to that zip, downloaded from before.
Then when I tried again the install happened correctly and my initial tests indicate that LDT is working as expected.

This basically says that plugins installed in your current Eclipse conflict with the plugins that JBoss OpenShift Tools (that you're apparently trying to install) is requiring:
"Only one of the following can be installed at once:"
Latest Eclipse Luna (but also the prior Kepler relase) tries to resolve such issues and offers you different alternatives like replacing the existing, conflicting plugins and remove all the ones that require these.
Like greg-449 pointed out, my current guess is that you're using an old Eclipse version (Kepler or even older). JBoss OpenShift Tools 2.6.0.Beta3 requires Eclipse Luna.
You installing latest development version of JBoss Openshif Tools form http://download.jboss.org/jbosstools/updates/development/luna/
I verified both 3.6.0 and 3.6.1 original clean installations and had no problems to install Openshift Tools.
Meantime I can see from error that your "m2e - Maven Integration for Eclipse 1.4.1.20140328-1905 (org.eclipse.m2e.feature.feature.group 1.4.1.20140328-1905)" doesn't match original version included in STS 3.6.0 which is "m2e - Maven Integration for Eclipse (includes Incubating components) 1.5.0.20140606-0033 org.eclipse.m2e.feature.feature.group".
I would suggest you to try to update to latest STS 3.6.1 and then install Openshift Tools again.
If you cannot update whole STS, I would try to update only m2e integration from luna repository before installing Openshif Tools.
I would also recommend to select "Contact all update sites during install to find required software" option during installation.

Getting Error while installing ClearCase plugin for Eclipse

I am installing IBM Clearcase plugin for Eclipse with following steps:
For Eclipse Juno >> Help > Install New Software...
click "Add...": http://www3.software.ibm.com/ibmdl/pub/software/rationalsdp/clearcase/60/update/windows/"
Click "OK"
Select the available packages and click "Finish".
I am getting below error while installation :

To: com.ibm.rational.clearcase.ccrefresh [7.6.0.v201105111445]
Where can I find the missing dependencies?
For a CCRC installation with a recent (3.4+) Eclipse, you should follow this technote.
The link you are using is to add ClearCase (as detailed in "Rational ClearCase SCM Adapter (For Eclipse), Version 7.6.0.0"), not CCRC, to Eclipse, and it won't work anyway, since you don't have ClearCase on your workstation.
Warning: See "System Requirements for the ClearCase Remote Client".
It only reference Eclipse3.x, no Eclipse 4.x.
An Eclipse Juno 4.2 might be too recent to support a CCRC plugin.

You need to install Subclipse.
If you are using Subversion for your version control system, you might be using either Subclipse or Subversive in Eclipse. Depending on which one you use, you should install the corresponding CloudBees toolkit adapter. You do not need the other one, and if you are using Git (or something else) you do not need either.
