How to downgrade Kotlin in Intellij 15 - plugins

For a project of mine I need to use Kotlin 1.0.0-1038 (beta), but to install it I probably need to uninstall the newer version of kotlin, but it has no uninstall button where it should have.
How would I downgrade Kotlin? IntelliJ IDEA 15.0.4

IMPORTANT UPD: as #yole commented, this is a bad solution as it will break things. There is no proper way to downgrade a bundled plugin without breaking the installation. Instead, consider upgrading the project to the up-to-date Kotlin version.
You have the plugin bundled with IntelliJ IDEA. On your own risk, you can delete its folder manually from IntelliJ IDEA installation (plugins/kotlin subfolder). After that you will be able to install whatever compatible version of the plugin from zip distribution, but your IDEA installation will be broken (see the comment).

Eclipse on Mac doesn't allow to downgrade (E)Git

I have updated my Eclipse for Committers to version 2021-12 (For MacOS), and found out that the default Git-plugin version installed is 6.0. Since Git deprecated some features who are still crucial to me, i tried to downgrade Git version to 5.11 (the last version i know that has the requested features).
But apparently Eclipse doesn't allow to uninstall any of it's Git add-ons, which is the first step in the downgrading process.
I tried to uninstall from different menu paths, but they all lead to failure. I also tried that with "Eclipse for Java developers" (non-committers), and with older versions of Eclipse, without success.
Does anyone know what can i do?
Thanks.
Like it says in the dialog, the Git Integration is required by something else you have installed. There's little unique about the "Eclipse for Committers" download, meaning if you can't uninstall something you want to uninstall, you can still start from the bare basics and then install more into it. You should start with an SDK download from https://download.eclipse.org/eclipse/downloads/ and then add the versions of software you actually want to it.

how to use intellij-leiningen-plugin in intellij idea 14

I don't know how to use leiningen plugin in IntellJ Idea14.
I have tried 2 ways:
I have downloaded from http://github.com/derkork/intellij-leiningen-plugin
and now how to use it
I have installed in config/plugins/Browse Repositories
but when I create new project
I can't see any leiningen project?
How can I fix it?
This plugin has been unmaintained for a long time. It's officially been replaced by Cursive, whose lein support was initially based on the source code from this plugin. It was generously donated by the plugin authors.

"Plugin Scala is incompatible with this installation" error with IntelliJ 14

From Browse Repositories in IntelliJ 14, the newest Scala plugin is version 1.5.2.
From the Scala plugin homepage for IntelliJ, the latest version (as of Aug 10, 2015) is 1.7.4. https://plugins.jetbrains.com/plugin/?id=1347
However, when I tried to install it from "Intall plugin from disk ..." after downloading scala-intellij-bin-1.7.4, I got this error:
What might be wrong?
On the link that you've provided you can see that compatible Intellij Idea builds for 1.7.4 version are 142.3553 — 143. The latest 14 Idea build has version lower than 142 - so it's incompatible with this plugin version. There is already EAP Intellij Idea 15 which you can download and install new scala plugin version on it.
I faced the same issue with 2020.2.4 Intellij IDEA. I just uninstalled the plugin and installed it again. Fixed the problem.
Try this way:
Go in settings - ctrl + shift + s
Plugins
Updates at the top
Push the button Update all
Done!
The best option is to directly install the Scala plugin from the marketplace. However, if you can't do it for some reason (say, HTTP proxy related), you can download the plugin and install in the IntelliJ. Finding the correct plugin is little tricky, I provided a screenshot below:
The supported products are provided and we will need to look closely for that. This plugin will only work for those products.

Eclipse keeps finding wrong version of plugin dependency

I'm trying to add a plugin dependency to org.eclipse.emf.ecore, because I'm using Ecore to do some modeling for my plugin. The only problem is that when I try to add it, the only version that matches is 2.4 and I can't find that 2.4 jar anywhere on my system, so I have no idea why Eclipse can only find this version and where Eclipse finds it.
In Eclipse's own plugins directory, I have version 2.9, so why can't it find this version? I want to use v 2.9, but no clue how can get Eclipse to match that version.
Any help is welcome, this has me perplexed!
Eclipse resolves dependencies against the currently set target platform. Make sure you have the right taget platform set, that includes org.eclipse.emf.ecore v. 2.9.
If you have not worked with the target platform before, take a look at this tutorial from Lars Vogel.

Cannot install SBT plugin for IntelliJ 12.1.6 CE on Mac

I would like to install the SBT plugin in IntelliJ 12.1.6 Community Edition (Mac) found here: http://blog.jetbrains.com/scala/2013/07/17/sbt-plugin-nightly-builds/
But after adding the repo I tried to install sbt-intellij-bin-0.1.5.8 but the download fails.
What might be the source of the problem?
The latest nightly version of the SBT plugin is not compatible with IDEA 12 anymore, only IDEA 13. If you download it manually and try to install an error message stating that will pop up, but for some reason (probably a bug) it isn't really visible when installing from a repository.
