Kotlin plugin is not maintained so don't bother installing it
Submitted by Nathan Niesen on Wed, 2022-07-20 19:56
The Kotlin Plugin for Eclipse (GitHub JetBrains/kotlin-eclipse project) is a dead/unsupported plugin that hasn't worked for a couple of years. Don't bother installing it because it will just break the JDT Package Explorer and other features. At least they finally stopped incrementing the "Eclipse Versions:"

You can get past the install issue by also installing Mylyn from the Marketplace. Unfortunately it won't do any good to install it because it's unmaintained and will just break Eclipse.

Re: StackoverflowError with Eclipse 2021-09
Submitted by Daniel Schaarschmidt on Mon, 2021-11-22 03:59
I guess it's not completely abandoned (yet). The just released new version 1.5.31 fixes the StackOverflowError.
But editing Kotlin Scripts is still impossible because the Jetbrains Youtrack-Issue KE-360 still exists leading to the error: "Cannot access script base class 'org.jetbrains.kotlin.core.script.template.ProjectScriptTemplate'
This happens with Gradle Build Scripts in Kotlin as well as with a new Kotlin Project and new Kotlin Script in it.
Broken with eclipse 4.20
Submitted by Giorgis Gamatos on Mon, 2021-08-23 16:53
Can you please update this plugin? Why is it even abandoned? If we want to use Kotlin we have to go with IntelliJ? This sucks guys.. please update your stuff.

I agree with this on the highest level. Honestly i really dont understand why Kotlin is being used more now over Groovy. Its makes things so much more complicated

Does not configure Gradle projects correctly
Submitted by Nathan Niesen on Tue, 2020-08-04 16:55
Gradle projects with Kotlin plugin do not get configured properly after Import or Refresh:
* Project Nature is not set correctly on Import
* Project and Classpath files are left in an invalid state after Refresh (Need to Remove and Re-Add Kotlin Nature).
Some other things that don't function as expected:
* Launchers for SpringBoot Applications throw errors about not finding the type
* Open Declaration (F3) doesn't work for mixed Kotlin/Java
* Changing the Kotlin Compiler JVM target version from the default 1.6 breaks the preference page if you don't fill in the JDK Home. Need to uninstall and reinstall to reset it.
Poor Plugin
Submitted by Faeem Ali on Thu, 2020-07-09 07:51
I've spent the last few hours fighting with this plugin. The problem I am having was reported 3 years ago and people are still using unofficial hacks from forum posts to get code deployed to tomcat. The recommended solution is "Buy and use IntelliJ".
Maven works, and the kotlin and java code compile and work correctly when using maven only. I have confirmed this by deploying to a tomcat installation outside eclipse.
So it seems the Kotlin dev team do not care about this plugin (integration was nowhere near as seamless as it is with IntelliJ), and It seems like Kotlin is treated as a second class citizen on everything but IntellliJ/Android Studio, in an attempt to get more sales.
I will be reverting to Java

Painful
Submitted by Ryan Dunn on Wed, 2019-10-30 16:27
Kotlin plugin for Eclipse is currently painful to use. If you try to use it in a mixed Java, Xtend, Kotlin project setup, it barely works and constantly throws 'Analysis Error'. Further, unit testing is completely busted as tests are not compiled for Eclipse and you get constant ClassNotFoundExceptions.

I have the same issue and I can't downgrade Eclipse for other reasons. I've filed https://youtrack.jetbrains.com/issue/KE-353 to track this, hope to have some feedback quickly. I suggest you comment there, as it's more visible to the Kotlin team!

The published version of this plugin is not yet compatible with the lastest version of Eclipse, ence it's filtered out from searches in the marketplace.
To solve the problem, try using the previous version of Eclipse.

Plugin version 0.8.11 doesn't work on Eclipse 2018-12
Submitted by Giuseppe Miscione on Wed, 2019-01-09 05:35
On a clean install of Eclipse 2018-12, in a brand new workspace, I installed the Kotlin plugin and then I created a Kotlin project. When I open a .kt file, the editor fails to startup with the following error:
org.eclipse.core.runtime.CoreException: Plug-in org.jetbrains.kotlin.ui was unable to load class org.jetbrains.kotlin.ui.editors.KotlinFileEditor.
I tried this on a kotin project created from the "New" wizard and also on new maven project to which I added the kotlin nature.

'False compile' error displayed in eclipse
Submitted by Arnaud MERGEY on Fri, 2018-05-18 05:23
Hello, a kotlin file is displaying an error marker with message
'when' expression must be exhaustive, add necessary 'BOOLEAN', 'DATE', 'NUMBER', 'STRING', 'TIMESTAMP' branches or 'else' branch instead
but this wrong as I have a case for each branches. The only way to have the error gone is to add an else branch, but this is wrong because if I add an enum value, I will not have error (because of the else) and I could miss to write proper branch for the new value.
By the way do you have some bug tracking system, where we could raised issues on the plugin ?

How to create a Multi-platform Project (MPP)
Is it possible to create a multi-platform project (MPP) with Eclipse Oxygen (latest release)? I cannot achieve to create a multi-platform-project as described in the Kotlin Language reference. It is possible to do that in IntelliJ IDEA 2017.3 EAP.
Will MPP support be available in the future?
