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 It's officially been replaced by Cursive, whose lein support was initially based on the source code from this plugin.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.

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).
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.
I recently installed the Scala IDE Eclipse Kepler, and I have trouble with scala.html template files and sbt files.
The other references online say that I can use "Template Editor" to edit the scala template. However, such template is not found in the IDE.
I also don't see any mentioning of the editor for .sbt files.
IntelliJ Idea has them all, but requires a fee.
Is there anything that I should install to edit all files related to scala and play framework?
The Play plugin for 2.11 (it seems you are using 2.11) is only available together with the 4.0 milestone 3 release, available here:
http://scala-ide.org/download/milestone.html
Unfortunately, the changes we needed to make in order to adapt to 2.11 made it too difficult to re-release it on 3.0.4. I hope the milestone release is good for you. We should have the next major release soon, though.
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.
I installed scala plugin for IntelliJ Idea 12, but it can't find sbt plugin for it for some reason. Has something changed?
The plugin is not in the default repository, but only in nightlies. Have you followed this (from the blog you link to):
Add the following URL to the list of custom plugin repositories in Settings | Plugins | Browse Repositories | Manage Repositories:
http://download.jetbrains.com/scala/sbt-nightly-leda.xml
It worked for me, after I added this repository I found the plugin.
I wasn't aware of this plugin, and just installed it myself... and it works. What tripped me up while installing is that there are a few third party SBT plugins floating around out there as well. The one you want is called "sbt-intellij-bin-0.1.49" (or some later version). Not SBT Executor, et al. Make sure you add the repository referred to on that webpage.
Install, restart IntelliJ. You should see an 'SBT Console' button along the bottom of the interface. Nice.. now I don't have to have a terminal window open to SBT taking up screen real estate...
